November, Mysteries of the Universe

Sun and Storms

As there really have been terrifying storms during November, I thought I would look at both subjects of Sun and Storms. November has been full of amazing and horrifying news.

Back in August 2013 scientists had been preparing us for the 11 year cycle of the sun ‘flipping’ polar magnetism occurring around now, the last weeks November. It obviously became my main research topic for the month.

3rd November 2013

A rare solar eclipse was seen across Africa, Europe and the US. For past and future details of these see Of this eclipse the website states:

“The final event of 2013 is the most interesting eclipse of the year. It is one of the rare hybrid or annular/total eclipses in which some sections of the path are annular while other parts are total. The duality comes about when the vertex of the Moon’s umbral shadow pierces Earth’s surface at some locations, but falls short of the planet along other sections of the path. The unusual geometry is due to the curvature of Earth’s surface that brings some geographic locations into the umbral while other positions are more distant and enter the antumbral rather than umbral shadow. In most cases, the central path begins annular, changes to total for the middle portion of the track, and reverts back to annular towards the end of the path. However, November 3 eclipse is even more unique because the central path begins annular and ends total. Because hybrid eclipses occur near the vertex of the Moon’s umbral/antumbral shadows, the central path is typically quite narrow.”

7th November 2013

An article in the Guardian
followed up on the Chelyabinsk meteor which hit in February of this year:

An international team of researchers, led by Olga Popova at the Russian Academy of Sciences, visited Chelyabinsk and 50 nearby villages in the weeks after the event to map the extent of the destruction. The shockwave left a trail of damage 55 miles on either side of the rock’s trajectory, according to a report in the journal, Science.

“Our goal was to understand all circumstances that resulted in the damaging shockwave that sent over 1,200 people to hospitals in the Chelyabinsk blast area that day,” said Peter Jenniskens at Nasa’s Ames Research Centre in California.

The unforeseen arrival of the meteor and the violence of its impact were a wake-up call, according to Qing-Zhu Yin, an author on the study at the University of California, Davis. “If humanity does not want to go the way of the dinosaurs, we need to study an event like this in detail,” he said.

Further details of the Chelyabinsk strike appear in two reports in the journal Nature. The first, led by Jirí Borovicka at the Academy of Sciences of the Czech Republic, traces the orbit of the meteor back to another object, known as asteroid 86039. This asteroid has also orbited close to Earth and was probably once part of the same rock as the Chelyabinsk meteor.

The second Nature study, led by Peter Brown at the University of Western Ontario, calculated the energy of the Chelyabinsk airbust at 400 to 600 kilotonnes of TNT, but found that scientists’ models for estimating damage from airbursts were off the mark. The glitch in the models means that the number of space rocks with sizes of the order of tens of metres, which pose a threat, may be ten times greater than previously thought.

This was a report at the time:

The Chelyabinsk meteor was a Near-Earth asteroid that entered Earth’s atmosphere over Russia on 15 February 2013 at about 09:20 YEKT (03:20 UTC), with an estimated speed of 18.6 km/s (over 41,000 mph or 66,960 km/h), almost 60 times the speed of sound.[1] It quickly became a brilliant superbolide meteor over the southern Ural region. The light from the meteor was brighter than the sun. It was observed over a wide area of the region and in neighbouring republics. Eyewitnesses also felt intense heat from the fireball. (added from

(The last time a six-mile-wide rock hit the planet was sixty-five million years ago, when it thundered into what is now the Yucatan Peninsula, creating a hundred-mile-wide crater. The climatological fallout contributed to the mass extinction of not just the dinosaurs but also some seventy-five per cent of all animal and plant life. If the smaller Chelyabinsk meteor had come in above a city like New York, it would have injured many more than the twelve hundred it did in Russia. Despite astronomers’ herculean efforts to detect and map all the potential threats—a catalogue of so-called Near Earth Objects now stands at just over ten thousand—astronomers are still unsure about the number of Chelyabinsk-sized bodies and how often they hit us.)

early November – 30th November 2013

Comet ISON stayed in our thoughts as it grazed the sun and then seemed to evaporate on 28th November, Thanksgiving in the USA. By 29th November speculation arose that something was still glowing after all, something seemed to survive the journey of the Comet. A video made by observing campaign member John Maclean shows the comet slicing toward the sun and then something — apparently ISON — emerging from the other side. Maclean is a fellow of the Royal Astronomical Society at Norman Lockyer Observatory Sidmouth in Devon, England.

The discovery stunned many in the comet-watching community and led some to nickname ISON the zombie comet.

Detected just over a year ago, by astronomers Vitali Nevski and Artyom Novichonok using a telescope near Kislovodsk, Russia. ISON is officially named C/2012 S1. The comet has passed through the inner solar system for the first time from outside it, the first time this has happened with so much technology monitoring its every move. Still fresh, this comet is thought to bear the pristine matter of the beginning of our solar system, a fossil relic of the solar system’s formation 4.5 billion years ago. It is believed to be straight from a haze of comets known as the Oort cloud on the fringes of the solar system, comets made from frozen balls of dust and gas in orbit around the sun. For whatever reason, ISON was propelled out of this cloud and drawn toward the heart of the solar system by the sun’s intense gravitational pull, taking 5.5 million-years to arrive at the sun. ISON swept about 730,000 miles over the sun’s surface Thursday about 2 p.m. ET.

Among NASA’s space telescopes taking a look: Swift, Hubble, Spitzer, Mars Reconnaissance Orbiter, Solar and Heliospheric Observatory or SOHO, Chandra, Mercury-orbiting Messenger, and the Stereo twin spacecraft. Thanks to the generous sharing of these images over the Internet, millions watched the approach to the sun. Witnessing something which had taken an inconceivable number of years to get to this point, it was an incredible honour to sit in my armchair and watch with others around the world.

Worth noting:

21st November 2013: Anniversary

Fifteen years ago the first module of the ISS (International Space Station) was launched on board a Russian rocket. Thanks to this innovation, the mysteries of space have been opened up to the world. During the past decade 15 countries have come together to design, assemble, occupy and conduct research inside and outside of the ISS, which is the largest and longest inhabited object to ever orbit the Earth.

It was on the 25th November when the Comet brightened suddenly, everyone became very excited.

Starting at 7 p.m. EST (0000 UTC) on Nov. 14, the comet’s outburst began, and its brightness quickly jumped to magnitude 5.9. By the following day, it had soared to magnitude 5.1 — a more than 13-fold increase in brightness in less than three-days. Nov. 20), ISON was positioned roughly between the bright star Spica and the planet Mercury. The comet was harder to see as it sped into the rising sun, and after Nov. 22 the comet was hidden by low altitude and the bright dawn twilight. 26th November,

Karl Battams, a comet scientist with the U.S. Naval Research Laboratory in Washington, D.C. who blogs on NASA’s Comet ISON Observing Campaign website put it this way on Monday, “Comet ISON is a dynamically new sungrazing comet, fresh in from the Oort Cloud, and the last time we saw an object like this was never! Furthermore, a sungrazing comet just three days from perihelion [closest approach to the sun] has never been studied in this kind of detail—we’re breaking new ground here! When we factor in your standard ‘comets are unpredictable’ disclaimer, what we have is a huge recipe for the unknown.”

Battams said. “Nonetheless, this has been one of the most extraordinary comets we have ever encountered, and just goes to reiterate how beautiful, dynamic and exciting our universe is.”

In January, it was travelling at about 64,000 kilometres per hour. and by November 21st it had accelerated to 240,000 km/h and on 28th November, when ISON comes in range of the sun, calculations are it is moving at an amazing1.3 million km/h.

As the 28th November arrived, all equipment that could be focused on the Comet was switched on beaming pictures and collecting vast amount of data. Although the Comet seemed to disappear as it grazed the sun, it has supplied an amazing amount of data since it has presented a unique event for researchers to analyse the data to further understand our universe.

The Sun has had two south poles for a year now. This amazing life source is forever absorbing human interest, and NASA leads the world with monitoring technology, leading scientists and massive data collection which it shares around the world.

I had to gain some basic understanding first before I read more about what the Sun is doing this month.

In the Forum I gained a further understanding of how the Earth and Sun relate:

“The Sun is a magnetic variable star at the center of our solar system that drives the space environment of the planets, including the Earth. The distance of the Sun from the Earth is approximately 93 million miles. At this distance, light travels from the Sun to Earth in about 8 minutes and 19 seconds. The Sun has a diameter of about 865,000 miles, about 109 times that of Earth. Its mass, about 330,000 times that of Earth, accounts for about 99.86% of the total mass of the Solar System. About three quarters of the Sun’s mass consists of hydrogen, while the rest is mostly helium. Less than 2% consists of heavier elements, including oxygen, carbon, neon, iron, and others. The Sun is neither a solid nor a gas but is actually plasma. This plasma is tenuous and gaseous near the surface, but gets denser down towards the Sun’s fusion core…………..

,,,,,,,,,,,,,,Stars like our Sun shine for nine to ten billion years. The Sun is about 4.5 billion years old, judging by the age of moon rocks. Based on this information, current astrophysical theory predicts that the Sun will become a red giant in about five billion (5,000,000,000) years.”

on reading the Solar and Stellar Activity Research Ream’s interesting report at, I understand from them “The driving force of the solar activity is the magnetic dynamo, whose signatures can be observed on magnetically active stars as well. The working of the solar dynamo shows cyclicities on several time scales, as the long-term monitoring of stars suggest similar behaviour.”

The Sun and its 11 year and 22 year Cycles

We are at the midpoint of Solar Cycle 24, which is the 11 year point when the Sun changes polarisation.

From NASA at some further explanations:

“The sun’s magnetic field changes polarity approximately every 11 years. It happens at the peak of each solar cycle as the sun’s inner magnetic dynamo re-organizes itself. The coming reversal will mark the midpoint of Solar Cycle 24. Half of ‘Solar Max’ will be behind us, with half yet to come.

Stanford’s Wilcox Solar Observatory, one of the few observatories in the world that monitor the sun’s polar magnetic fields. have been tracking the sun’s polar magnetism since 1976, using Magnetograms. They are currently monitoring their fourth reversal of the sun’s magnetic field which occur every 11 years.”

However, this particular flip has puzzled some scientists because one magnetic pole of the Sun appeared to flip “too early” last year. For a year now the sun has had two south poles.

Back in 2000, during Cycle 23, the sun had two north poles!

“The south pole never really vanished,” notes Riley. It migrated north and, for a while, became a band of south magnetic flux smeared around the Sun’s equator. By May 2000 the south pole had returned to its usual spot near the Sun’s southern spin axis–but not for long. In 2001 the solar magnetic field completely flipped; the south and north poles swapped positions, which is how they remain now.

The page providing this information said:

A supercomputer on Earth. A spacecraft hundreds of millions of kilometers away. Working together they’re getting us ready for the next time the Sun sprouts an extra north pole … or something stranger yet.

Now they have two south poles to ponder.

A further helpful piece from

“Unlike the earth, the sun is not a solid. The sun is a giant ball of bubbling, shifting, swirling gases. As a result, different parts of the sun can rotate at different speeds. In fact, parts of the sun near the equator rotate much faster than parts of the sun near the poles. Because rotation is what causes the magnetic field, the different rotation speeds cause the magnetic field to twist and knot. For the purpose of illustration, think of a magnetic field as a collection of magnetic field lines that act much likes ropes attached to the North and South poles. As the parts of the sun near the equator rotate faster and get ahead of the rest of the sun, they drag the magnetic field lines ahead, causing them to twist and knot.

Magnetic field lines tend to guide charged particles. The hydrogen ions of the sun are charged, so they are forced to travel somewhat along the magnetic field lines. A knot in the magnetic field lines on the surface of the sun therefore leads to a pocket of hot gas getting trapped on the surface which is unable to boil into space in the usual way. We see this region of trapped gas as a dark spot on the sun’s surface and call it a “sunspot”. Eventually, the knot in the magnetic field either relaxes and the sunspot disappears, or the knot becomes so twisted that the magnetic field lines snap. When the field lines snap, they can no longer keep the hot gas trapped. At this point, the hot gas has been building up pressure, so the snapped field lines causes a violent release of the hot gas. The glowing gas erupts into space, sending a strong fireball of light and matter out into the solar system. This fireball is known as a “solar flare”.

Sunspots and solar flares are therefore caused by a knot in the sun’s magnetic field. The more knots there are, the more sunspots and solar flares there are. Now, remember that the knotting is caused by the equator spinning too fast. As time progresses, the equator gets more and more ahead, the magnetic field lines get more and more knotted, and there are therefore more sun spots and solar flares. This process can not go on forever (the magnetic field cannot become infinitely knotted). Every eleven years the sun’s magnetic field gets so knotted that it all snaps at once. This snap is different than a single break that takes place on a sun spot. The magnetic field lines break all over the place. This colossal snapping every eleven years causes the magnetic field of the sun to flip so that the North Pole switches places with the South pole. This colossal snapping also causes the magnetic field lines to reset back to an unknotted state, leading to few sun spots and solar flares. The sun has been charging ahead on this 11-year cycle of being unknotted, somewhat knotted, very knotted, snapped, unknotted, somewhat knotted, etc. for millions of years. The number of sunspots per month, the number of solar flares, the amount of knotting, and even the brightness of the sun all follow this 11 year cycle.

This article reassures us all that :Solar flares have little direct effect on life on earth’s surface, thanks to the protective cover of earth’s atmosphere and magnetic field. The sun’s magnetic field has been flipping every eleven years for millions of years without any harm to life on earth. ……………..

At they explain:

“When solar physicists talk about solar field reversals, their conversation often centers on the “current sheet.” The current sheet is a sprawling surface jutting outward from the sun’s equator where the sun’s slowly-rotating magnetic field induces an electrical current. The current itself is small, only one ten-billionth of an amp per square meter (0.0000000001 amps/m2), but there’s a lot of it: the amperage flows through a region 10,000 km thick and billions of kilometers wide. Electrically speaking, the entire heliosphere is organized around this enormous sheet.

During field reversals, the current sheet becomes very wavy. Scherrer likens the undulations to the seams on a baseball. As Earth orbits the sun, we dip in and out of the current sheet. Transitions from one side to another can stir up stormy space weather around our planet.

Cosmic rays are also affected. These are high-energy particles accelerated to nearly light speed by supernova explosions and other violent events in the galaxy. Cosmic rays are a danger to astronauts and space probes, and some researchers say they might affect the cloudiness and climate of Earth. The current sheet acts as a barrier to cosmic rays, deflecting them as they attempt to penetrate the inner solar system. A wavy, crinkly sheet acts as a better shield against these energetic particles from deep space.”

According to NASA, the intensity of geomagnetic storms during Solar Cycle 24 may be elevated in some areas where the Earth’s magnetic field is weaker than expected. This fact was discovered by the THEMIS spacecraft in 2008. A 20-fold increase in particle counts that penetrate the Earth’s magnetic field may be expected. Solar Cycle 24 is being studied for its potential effects on Earth. ”

Solar Cycles and Geomagnetic Storms

Geogmagnetic storms

These are temporary disturbances of the Earth’s magnetosphere caused by solar wind shock wave and/or cloud of magnetic field which strikes the Earth;s magnetic field 24 to 36 hours after the event. When Earth-directed, CMEs can cause a space weather phenomenon called a geomagnetic storm, which occurs when they successfully connect up with the outside of Earth’s magnetic envelope.

Alerts are provided at, so on

19th November 2013 this was issued:

Potential Impacts: Area of impact centered on sub-solar point on the sunlit side of Earth. Extent of blackout of HF (high frequency) radio communication dependent upon current X-ray Flux intensity. For real-time information on affected area and expected duration

Those working with space projects know only too well of the dangers, for example the international space station must be ‘re-boosted’ every three months to prevent it from burning up in the atmosphere.

The Skylab station on July 11, 1979 reentered prematurely because of a solar storm event.

Solar Cycle 23 was studied and found many worrying impacts, see

But an episode in the history of geomagnetic storms : August 28 – September 2, 1859 warned us of what was to come as we increased our technology and communication abilities.

American theoretical physicist, Michio Kaku, has been warning governments to protect their infrastructures from a possible solar storm which might be as extreme as that witnessed in 1859.

From it makes fascinating reading:

The Storm of 1859 was the first event recorded by humans from a truly global perspective, not to be repeated until the eruption of Krakatoa in 1883 turned the sunsets red and crimson the world-over. Newspapers such as the New York Times were active in running extensive stories about the 1859 solar storm, and collecting reports from other countries. The great geomagnetic storm of 1859 is really composed of two closely spaced massive worldwide auroral events. The first event began on August 28th and the second began on September 2nd. It is the storm on September 2nd that results from the Carrington-Hodgson white light flare that occurred on the sun September 1st.

Engineers are working on solutions: see

Stuart Nathan says, engineers are beginning to understand how space weather could affect today’s technology. Referring to the 1859 event, he says:

“The Northern Lights are normally confined to the highest latitudes within the Arctic Circle, but one day in 1859 the shimmering curtains of light descended far down the globe. Miners in the Rockies thought the bright light behind the mountains was the breaking dawn, clocks being harder to come by than alcohol. The display reached as far south as the Caribbean.”

…………..for telegraph workers in Europe and North America the night was terrifying. The systems went haywire. Operators recoiled from electric shocks. Pylons emitted showers of sparks. Telegraph paper spontaneously caught fire. Some telegraph systems seemed to send and receive messages even though they had been disconnected from their power supplies.

In London, an amateur astronomer called Robert Carrington saw the news of these occurrences and began to think. The previous day, while observing the sun, he had seen a bright flash seeming to erupt from the edge of the solar disc. Could this be connected with the aurora and the strange electrical disturbances?…………….

Carrington was the first to make the connection between the activity of the sun and geomagnetic storms, and the 1859 event, now known as the Carrington Superstorm, is the most powerful solar storm ever recorded.

There are gripping articles available to read from around the world, describing the amazing northern lights at

February 2013 and the launch of SDO

Earlier this year NASA’s Solar Dynamics Observatory satellite was launched. 3 days later, on Valentine’s Day, a solar storm was intense enough to momentarily overwhelm the detectors on NASA’s Solar Dynamics Observatory satellite.

but now the website informs us of the mission of this amazing satellite. We can read that space weather is not just creating pretty auroras.

“Particles and ionizing radiation from these solar storm events propagate to Earth and enter at Earth’s poles. In some instances, aurora result. The increased particles and radiation produce space weather effects such as changing the ionizing radiation doses for passengers…….
I suggest you look at…….and electronics on polar aircraft flights, disabling satellites, causing power grid failures, and disrupting signals for the global positioning system, television, and telecommunications ………..see details of the impact back in 2002 see……………..Understanding the science of space weather can lead to a capability to predict space weather.”

Thanks to this satellite, the most amazing images of the sun can be seen at as the poles battle through their process of switching. Truly astonishing pictures. What a great time to have a career related to these studies of our galaxy. Great time for physicists. but, for amateurs like me, how lucky these images and explanations are sitting on the internet for me to educate myself from the comfort of my armchair. It is wondrous and yet unnerving to think solar storms are on the increase and our electronic world is so vulnerable to this phenomenon.

Is Climate Change also being impacted by the 11 year cycle?

As the Sun is a variable star, this means its magnetic activity and total irradiance vary on a timescale of approximately 11 years.

It is this total solar irradiance which NASA monitors to estimate any possible influence on climate change, Could this energy vary enough to change Earth’s climate?

NASA educates us with:

“Energy from sunlight is not spread evenly over Earth. One hemisphere is always dark, receiving no solar radiation at all. On the daylight side, only the point directly under the Sun receives full-intensity solar radiation. From the equator to the poles, the Sun’ rays meet Earth at smaller and smaller angles, and the light gets spread over larger and larger surface areas ”

The Sun’s magnetic field dominates the solar atmosphere, structures it, drives much of the atmospheric dynamics and produces all the observed energetic phenomena, like flares, jets, coronal mass ejections, etc. Magnetic field and associated solar activity reach all the way into the heliosphere, whose physical parameters, e.g. magnetic field strength and gas pressure follow the variability of solar magnetic activity.”…… and

“Averaged over the entire planet, the amount of sunlight arriving at the top of Earth’s atmosphere is only one-fourth of the total solar irradiance, or approximately 340 watts per square meter.

When the flow of incoming solar energy is balanced by an equal flow of heat to space, Earth is in radiative equilibrium, and global temperature is relatively stable. Anything that increases or decreases the amount of incoming or outgoing energy disturbs Earth’s radiative equilibrium; global temperatures must rise or fall in response.”

Whilst waiting to hear more about confirmation of the ‘flip’, around the world various disastrous weather systems impacted during early to mid November. With advances in technology there are emerging reports of developing tools to predict weather, such as:

Using historical data to understand weather patterns

“Bin Guan, an earth sciences researcher at the University of California, Los Angeles and NASA’s Jet Propulsion Laboratory. at NASA say they have identified a rare weather pattern that will help forecasters predict when California will experience periods of intense and potentially prolonged wet weather.

Guan’s study – a collaboration among scientists at UCLA and the National Oceanic and Atmospheric Administration – found a conclusive link between the alignment of two weather patterns in the Northern Hemisphere and the formation of an “atmospheric river” headed for California.

The results were gleaned in part from data provided by NASA’s 11-year-old Aqua weather satellite – one of more than 40 weather-related satellites that circle the globe.

Atmospheric rivers are narrow bands of wind, often a mile high, that can pack the punch of a hurricane. As they move over the ocean, they become laden with water vapor – and can carry with them as much water as the Mississippi River dumps into the Gulf of Mexico in an average week.

To arrive at his findings, Guan looked at 50 years of data, including information from the California Department of Water Resources for the winter of 2010-11, when 20 atmospheric river storms made landfall.

The two weather systems studied were the Arctic Oscillation* and Pacific/North American teleconnection*. These weather patterns rarely align in a certain way, but when they do the result is intense weather for California. Most troubling is that the weather events have the possibility of playing out over an extended period of time – such as the winter storms in 2010-11, said Guan.

The findings will allow scientists to identify the frequency of the wet weather events, said Duane Waliser, chief scientist in Earth Science and Technology at JPL.”

*Arctic Oscillation (AO)

(Also called the Northern Annular Mode, or NAM). In its positive phase, sea-level pressure is relatively low in the Arctic and high in the midlatitude region to the south. This is associated with a stronger and more northerly vortex encircling the pole and fewer intrusions of cold Arctic air into midlatitudes. The negative phase, with higher-than-usual pressure in the Arctic and lower-than-usual pressure in midlatitudes, features a weaker, more variable vortex and a greater risk of Arctic outbreaks of cold air into eastern North America and Europe. The AO is closely associated with the North Atlantic Oscillation.

The AO trended toward positive values from the 1960s until the early to mid-1990s, with more variability after that point. The winters of 2009–10 and 2010–11 experienced extreme negative values. Large ups and downs on shorter timescales may be in store, but the story looks different in the long run. Based on computer-model results and physical reasoning, scientists have expected the global increase in greenhouse gases to foster a slightly positive AO trend over the coming century. However, research continues on how factors such as melting sea ice might influence the AO’s future, and natural variations will remain important.

Pacific/North American Pattern (PNA)

A prominent teleconnection pattern of climate variability affecting North America, especially in winter. The PNA is shaped by the location of the polar jet stream as it flows from eastern Asia across the Pacific to North America. During the PNA’s positive phase, the jet stream flows more directly across the Pacific, increasing the odds of above-average temperatures across the U.S. West Coast and western Canada. This positive PNA pattern is more likely to occur when an El Niño* event is in progress, while a negative PNA pattern is more likely during La Niña* (see ENSO).

El Niño

The most dominant pattern responsible for interannual, or year-to-year, climate variability across the globe. During an El Niño event, warmer-than-normal sea-surface temperatures occur in the central and eastern equatorial Pacific, while cooler-than-normal temperatures are observed in the western part of the tropical Pacific. In addition, convection over the equatorial Pacific tends to be farther east than the climatological average, bringing more rain to the U.S. Pacific coast and drought to Australia, among other teleconnections. El Niño is the warm (or positive) phase of the El Niño–Southern Oscillation, or ENSO; its structural opposite is La Niña, the cool (negative) phase. Trade winds are weaker than usual during El Niño and stronger than usual during La Niña.

El Niño (Spanish for “The Baby Boy” of the Christmas story) was named more than 100 years ago by Peruvian fishers who noticed the warming water off their shores around Christmas time. El Niño events recur at intervals ranging from about two to seven years and typically last from one to three years. Researchers believe El Niño behavior could change with global warming, although the exact nature of this change remains uncertain.

La Niña

The cool phase of the El Niño–Southern Oscillation, or ENSO. During a La Niña event, cooler-than-normal sea-surface temperatures (SSTs) occur in the central and eastern equatorial Pacific and warmer-than-normal SSTS are measured in the western part of the tropical Pacific. During La Niña, convection over the western Pacific tends to be farther west than the climatological average, bringing heavier-than-usual and more persistent rains to Indonesia and northern Australia, among other teleconnections. Researchers named La Niña (“The Baby Girl” in Spanish) to indicate the opposite phase of El Niño (“The Baby Boy” of the Christmas story); an alternate name is El Viejo (“The Old Man.”). Like its brother, La Niña recurs at intervals ranging from about two to seven years, with events typically lasting from one to three years. Researchers believe La Niña behavior could change with global warming, although the exact nature of this change remains uncertain.

2013 Weather Events

The jet stream seems to be behaving unexpectedly in a series of weather events it has contributed to which have been most alarming. At they are considering ice melt might be part of the process which impacts on the jet stream behaviour.

“A new study published in the journal Environmental Research Letters suggests that a loss of Arctic sea ice caused the jet stream to shift further south, thus contributing to an extraordinary run of wet summers experienced by Britain and northwest Europe between 2007 and 2012…………

Typically the jet stream lies between Iceland and Scotland during the summer and weather systems pass north of Britain, but a southerly shift can bring unseasonably wet weather to Britain, which can be unwanted by local farmers and summer tourists in Britain……………

The research team reported that the average extent of Arctic sea ice is declining by about half a million square kilometers per decade, an area equivalent to almost twice the size of the UK.”

Here in the UK we had hurricane-force winds (apparently not a ‘hurricane’ which cannot happen unless the Atlantic sea becomes heated to around 26 degrees, which is thought unlikely in the vicinity of the UK).

The first 6 months of 2013 are nicely documented on

We need more of this kind of work. We should work on

Then there are volcanoes. These also affect our weather:

26 – 27 August 1883

One only has to read about the eruption of Krakatoa to understand the impact worldwide.

The eruption of the volcano at Krakatoa, Indonesia in the Pacific Ocean and was a major disaster. The entire island of Krakatoa was simply blown apart, and the resulting tsunami killed tens of thousands of people on other islands in the vicinity.

The volcanic dust thrown into the atmosphere affected the weather around the world, and people as far away as Britain and the United States saw bizarre red sunsets caused by particles in the atmosphere. (see Turner paintings)

Krakatoa showed fresh eruptions in September 2012. This month we have Sinabung (Sumatra, Indonesia): Ash emissions and explosions continue.

Weather implications:

The main effect on weather right near a volcano is that there is often a lot of rain, lightning, and thunder during an eruption. This is because all the ash particles that are thrown up into the atmosphere are good at attracting/collecting water droplets. We don’t quite know exactly how the lightning is caused but it probably involves the particles moving through the air and separating positively and negatively charged particles.

World-wide affects of volcanic eruptions only happens when there are large explosive eruptions that throw material into the stratosphere. If it only gets into the troposphere it gets flushed out by rain

Volcanism produces about 3% of the total CO2 with the other 97% coming from anthropogenic sources.

Some weather events of 2013 around the world to end of November

January 2013

Monsoonal rains inundated parts of northeastern Peninsular Malaysia in late December 2012 and early January 2013. As much as 300 millimeters (12 inches) of precipitation fell over a two-week period.

Heavy monsoon rains impact more than 10 million residents in Jakarta, Indonesia. More than 40 people die, while more than 100,000 are left without homes. The heavy rainfall causes infrastructure problems, like a collapsed dike, that lead to a flooded central business district and train cancellations.

January becomes the hottest month ever experienced in Australia, breaking a record (for both mean and maximum temperatures) in the 103-year record-keeping period.

States throught the Northeast United States experience massive snowfall and blizzard conditions. The largest snowfall from a single storm is recorded in Portland, Maine (31.9 inches), while the sixth-largest snowstorm hits Boston. Hamden, Connecticut witnesses 40 inches of snowfall from the same storm system.

February 2013

Tropical storm Haruna starts in the Mozambique channel and makes its way to Madagascar by late February, leading to at least 26 deaths. Agriculture is heavily affected, exacerbating food security concerns. Emergency relief efforts are slow due to the weather.

Heavy winter storms hit the central United States, affecting the Texas pandhandle, western Oklahoma, and other areas. Wichita, Kansas sees record snowfall, receiving 21.2 inches of snow in February (the previous record was 20.5 inches). Amarillo, Texas is covered in snow drifts, some greater than 10 feet in height.

March 2013

Heavy rains across several parts of Africa result in flash floods and destroyed crops. More than 1,300 residents in the Mbale district of Uganda are displaced, while more than 220 homes suffer damages.

Extreme drought hits New Zealand – deemed the worst drought in 30 years – leading to an estimated loss in export revenue of $820 million USD. Outdoor water use bans and fire bands are implemented, while cattle and sheep are slaughtered due to lack of water and food.

March 2013 is China’s second-warmest March – after 2008 – since record keeping started more than half a century ago.

April 2013

Spain experiences its wettest March on record, with precipitation levels more than three times the 1971-2000 average.

Year-to-date rainfall is the driest on record, at 3.59 inches in California (9.49 inches below average).

In Vienna, Austria, the time period between the last ice day and the first day of summer (25 days) is the shortest since record-keeping began in 1872.

The Central United States experiences extensive flooding, causing rivers to reach record high levels in Illinois, Iowa and Michigan.

April 2013 ranks as Australia’s fifth-warmest average maximum temperature since recordkeeping began at the turn of the 20th century. Temperatures are 1.64°C (2.95°F) above the 1961–1990 average.

May 2013

2013 brings China the wettest May in the the last four decades. Rainfall is 23 percent above average.

In Eurasia, May snow cover extent is the lowest on record for the month. Record-keeping began roughly 45 years ago.

Tropical Cyclone Mahasan hits Bangladesh, affecting almost 1.3 million people. 1.1 million people evacuate to cyclone shelters, almost 50,000 homes are destroyed, and another 45,000 homes are badly damaged. More than a dozen people die.

In Moore, Oklahoma, a severe tornado destroys thousands of houses and businesses, leading to more than 20 deaths. Just 11 days later near El Reno, Oklahoma, another severe tornado hits. Its path is 2.6 miles wide, the widest tornado ever observed in the United States.

The third-warmest May (tied with 1998 and 2005) on record across global land and ocean surfaces occurs, with temperatures at 0.66°C (1.19°F) above the 20th century average.

June 2013

Snow cover in the Northern Hemisphere is the fourth-lowest since 1967, following the three years with the lowest recorded snow cover in 2012, 2010, and 2011, respectively.

Flash floods and landslides in northern India kill more than 1,000 people and leave thousands missing.

One of the most severe heat waves comes to North America. The hottest June temperature on Earth is recorded in Death Valley, California (129.2°F (54.0°C)).

19 firefighters lose their lives battling wildfires in Prescott, Arizona – the single deadliest incident for firefighters in the United States since 9/11.”

(July to Oct data located by me from the Internet)

Oct 28 2013

“A savage coastal storm powered by hurricane-force gusts slashed its way through Britain and western Europe on Monday, felling trees, flooding lowlands and snarling traffic in the air, at sea and on land. At least 13 people were reported killed.

It was one of the worst storms to hit the region in years. The deadly tempest had no formal name — and wasn’t officially classified as a hurricane due to a meteorological standard — but it was dubbed the St. Jude storm (after the patron saint of lost causes) and “stormageddon” on social networks.

Gusts of 99 miles per hour were reported on the Isle of Wight in southern England, while gusts up to 80 mph hit the British mainland. Later in the day, parts of Denmark saw record gusts up of to 120 mph and an autobahn in central Germany was shut down by gusts up to 62 mph.

“This was not just a British storm,” said meteorologist Nick Wiltgen. “The core of powerful winds marched relentlessly east, raking northern France and the Low Countries before slamming into northern Germany, Denmark, and southern Sweden. That latter phase in particular was exceptionally intense, with a 105-mph gust in extreme northern Germany and many many places gusting over 85 mph in the surrounding area.”

Wiltgen warned the high winds would sweep across the southern Baltic Sea and into the countries of Estonia, Latvia, and Lithuania Monday night.”

30th Oct 2013 (see Halloween storm of 1991), a mighty storm hit the the Mid-West and up into Canada on Halloween.

It was not as horrific as in 1991, but was bad – see

Dangerous storms marched east on Halloween night and into Friday morning, creating numerous reports of flooding and wind damage, some of which was caused by reported tornadoes.

“An area of low pressure intensified rapidly as it moved from the Midwest into eastern Canada Thursday into early Friday,” said meteorologist Chris Dolce. “This resulted in numerous reports of high winds, wind damage and a few tornadoes from the lower and middle Mississippi Valleys into the Ohio Valley and central Appalachians.”

According to The Weather Channel senior meteorologist Stu Ostro, the Halloween windstorm could be considered a “meteorological bomb”, which occurs when the central pressure within a mid-latitude cyclone — such as the one present during the Halloween severe weather — falls on average at least one millibar per hour for 24 hours………..Severe weather expert Dr. Greg Forbes states that at least 29 confirmed tornadoes in seven states from Texas to Ohio touched down on Thursday into the early morning hours of Friday. According to Dr. Forbes, this is a new record for the most confirmed tornadoes on any Halloween on record in the U.S. Most of these were rated EF0 and EF1, though an EF2 tornado touched down near Baker, Mo.

Drought in the US

A long lasting drought has been ongoing since April 2013 in about 34% of the US – see

“U.S. Drought Monitor Update for November 5, 2013
Submitted by susan.osborne on Thu, 11/07/2013 – 12:04pm
November 5, 2013 U.S. Drought Monitor Map

According to the November 5, 2013 U.S. Drought Monitor, moderate to exceptional drought covers 32.2% of the contiguous United States, a decrease from last week’s 34.7%. However, the worst drought categories (extreme to exceptional drought) increased slightly from 2.8% last week to 2.9%. A frontal low pressure system dumped heavy rain across parts of the Southern Plains and Midwest, with cool dry air following behind it. The rain improved drought conditions in the Plains and Midwest, while coastal rain and mountain snow showers trimmed some drought areas in the West, but drought expanded in Hawaii.”

most of us are aware of the horrific Typhoon which hit the Philippines:

NOV. 9, 2013: Super Typhoon Haiyan – Yolanda, as the storm is known in the Philippines – on Thursday, November 7, became the strongest typhoon or hurricane of 2013 and one of the strongest storms ever recorded. The storm plowed across the Philippine islands after making landfall on Samar, in the region of Eastern Visayas, with maximum sustained winds at 195 mph. That’s well above the Category 5 classification used for Atlantic and East Pacific hurricanes and just 6 mph shy of an EF-5 tornado.

This storm made Katrina look like a squall.

Then the Mid West of America:

17 Nov 2013 meteorologists for the National Weather Service have determined that at least 16 tornadoes struck Illinois and northwest Indiana

Midwest US Cleans up 2013’s Biggest Severe Weather Outbreak

Damage surveys continue in the Midwest U.S. after a stunning and violent late-season severe weather outbreak swept through on Sunday, killing at least eight people and leaving widespread significant damage.

Two violent EF-4 tornadoes and one strong EF-3 tornado hit Illinois, killing six, making Sunday Illinois’ deadliest November day for tornadoes in its history. The most widespread damage from Sunday’s outbreak occurred in the town of Washington (population 16,000), about 140 miles southwest of Chicago, where a violent EF-4 tornado destroyed or heavily damaged 250 – 500 homes and an apartment complex.

NOAA’s Storm Prediction Center logged 85 preliminary tornado reports from Sunday, along with 455 reports of high wind gusts and 32 reports of hail. Seventeen of the wind gusts were in excess of 74 mph (hurricane strength.) The grand total of 572 severe weather reports (filtered to remove duplicates) for the day were the most of any day of 2013, surpassing the 538 total reports from June 13. The 85 preliminary tornado reports is also the highest for any day of 2013, surpassing the 62 reports from January 29.

Sunday’s November tornado outbreak: how rare?

Sunday’s outbreak will probably rank as the second to fourth most prolific November tornado outbreak since 1950. But what was really remarkable about the outbreak was how far north it extended. With three confirmed tornadoes on Sunday, Michigan has increased its total number November tornadoes observed since 1950 by 50%, from six to nine. Prior to Sunday, Indiana had recorded 57 November tornadoes. That total increased by 26 on Sunday, which was the 3rd busiest day for tornadoes in Indiana history (the record: 37 tornadoes on June 2, 1990.) Seven confirmed tornadoes occurred in the 23-county region of Northeast Illinois and Northwest Indiana serviced by the Chicago NWS. Prior to Sunday’s tornado outbreak, there had been just twelve November tornadoes in this region since accurate tornado records began in 1950. The 101 tornado warnings issued in Illinois on Sunday represented 52% of all November tornado warnings issued in the state since 1986. The two EF-4 tornadoes that struck Illinois were the 2nd and 4th most northerly EF-4s ever recorded in the U.S. during the month of November, according to data from the Tornado History Project. Prior to Sunday, only twenty EF-4s had occurred in the U.S. in November dating back to 1950. Also notable is the fact that the intensity and areal extent of this severe weather outbreak resulted in widespread damage over a huge area, making it possible that this will be the first November severe weather outbreak in history to exceed $1 billion in damages. November severe weather outbreaks are rare enough and our database poor enough that we cannot make any definitive statements on how climate change may be affecting them, but one would expect to see cold-season severe weather events become increasingly common farther to the north in a warming climate.

November 19, 2013

Sardinia: Cyclone* Cleopatra was the worst storm in decades, rivers burst their banks, cars were swept away and bridges collapsed in the towns of Olbia and near Nuoro. Cleopatra dropped 450mm of rain in an hour and a half overnight.. People were vulnerable, many living in poor quality buildings, particularly in coastal areas. Cleopatra also given the name Ruven by the Free University of Berlin, was an extratropical cyclone in the western Mediterranean Basin in November 2013.The low pressure system developed slow-moving embedded thunderstorm complexes, as cold air flowing from the north entered the Mediterranean and interacted with warm moist air to the east.


In meteorology, a cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth. This is usually characterized by inward spiraling winds that rotate anti-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth.

Most large-scale cyclonic circulations are centered on areas of low atmospheric pressure. The largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic scale.

According to National Hurricane Centre glossary,( warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within synoptic scale.Mesocyclones, tornadoes and dust devils lie within the smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the Tropical Upper Tropospheric Trough during the summer months in the Northern Hemisphere.

Cyclones have also been seen on extraterrestrial planets, such as Mars and Neptune.Cyclogenesis describes the process of cyclone formation and intensification.Extratropical cyclones form as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones. These zones contract to form weather fronts as the cyclonic circulation closes and intensifies. Later in their life cycle, cyclones occlude as cold core systems. A cyclone’s track is guided over the course of its 2 to 6 day life cycle by the steering flow of the cancer or subtropical jet stream.

22 November 2013

Cyclone Helen has made landfall across the eastern coastline of India bringing along strong winds and heavy rain. 13 hectares of crops were destroyed by flooding.

24th November 2013

JAKARTA: Indonesia ordered the evacuation of 15,000 residents near an active volcano in the west of the vast archipelago on Sunday as authorities raised the alert for the emergency to the highest level.

Mount Sinabung on the island of Sumatra has become increasingly active in recent months, spewing columns of ash several km into the air.

Snapshot of Volcanic activity in the world

Volcanic activity worldwide 26 Nov 2013: Merapi, Santa María / Santiaguito, Pacaya, Fuego, Popocat
Tuesday Nov 26, 2013 18:57 PM |

Etna (Sicily, Italy): No changes in activity have occurred since yesterday. Very occasionally, glow from the summit vent at the NSEC and from a vent at its southern base is visible, suggesting ongoing sporadic deep-seated explosions inside the cone. Tremor is low at the moment.

Ulawun (New Britain, Papua New Guinea): Activity continues. Darwin VAAC reported a small gas and perhaps ash plume at 12,000 ft (3.6 km) altitude this morning.

Sinabung (Sumatra, Indonesia): Ash emissions and explosions continue. So far, about 18,000 people have been evacuated from the most endangered zones in a radius of 5 km around the volcano.

Merapi (Central Java): Particular vigilance should be maintained to monitor the volcano. A large crack, about 230 m long and 50 m wide, has appeared in the lava dome that had been emplaced in the summit crater at the end of the 2010 eruption. It increases the current risk of sudden collapse of the dome, resulting in rock avalanches and dangerous pyroclastic flows. Even a smaller phreatic explosion than the one from 18 Nov could trigger this.

Popocatépetl (Central Mexico): No significant changes in activity have occurred. Only 8 weak emissions / explosions were recorded by CENAPRED during the latest 24 hr observation interval.

Santa María / Santiaguito (Guatemala): The INSIVUMEH observatory reports weak to moderate explosions with ash plumes up to 700 m height and constant block avalanches from the rims of the Caliente lava dome, sign that effusive activity has increased somewhat.

Pacaya (Guatemala): Strombolian activity continues, but has been weak over the past days.

Fuego (Guatemala): The lava flow on the upper southern slope was no longer active this morning (while it was still 100 m long yesterday). The volcano is back to its typical mild explosive activity from the summit crater with strombolian bursts generating ash plumes up to about 600 m high, sometimes accompanied by loud shock waves.

Jebel Zubair (Red Sea): Satellite images show signs of ongoing activity (steam plume, discolored water) at the new island at least until 20 November. A satellite image from 24 November shows no such signs any more, suggesting that the activity has stopped or paused.

Nov 27, 2013

Suwanose-jima volcano (Japan): new eruptions reported

Explosive activity has resumed at the remote volcano in the Tokara Island chain. VAAC Tokyo reported explosions yesterday and this morning, with ash plumes rising to 4,000-6,000 ft (1.2-1.8 km) altitude.

“There was a modest fireball over southern Quebec just after 0047 (Universal Time = 7:47 p.m. EST),” writes Peter Brown, director of the Centre for Planetary Science and Exploration at the University of Western Ontario.

28th November 2013

Mount Etna

A new paroxysm has started at the New SE crater. Following weak strombolian activity during the past days, this afternoon, started to rise steeply this afternoon. At the time of this update, there are increasingly strong strombolian explosions or pulsating lava fountains at the New SE crater and an ash plume has started to rise. Bad weather inhibits good observations, but occasional views can be obtained especially from the NE side.

As November 30th arrives, I used for events which happened relevant to this blog.

1954 – 1st meteorite known to strike a woman (Liz Hodges-Sylacauga Ala)

1988 – Cyclone lashes Bangladesh, Eastern India; 317 killed

And as November ends, we now have a new island south of Tokyo. A small island that was formed by a volcanic eruption last month. The eruption was the first reported in the area since the mid-1970s. Most volcanic activity there goes undetected, because it goes on deep below the surface on the seabed along the Izu-Ogasawara-Marianas Trench. About 660 feet in diameter, the new island is just off the coast of Nishinoshima in the Ogasawara chain, which is also known as the Bonin Islands. Maybe this volcanic activity killed the oarfish which were washed up on the California coast so dramatically on 18th and 22 October. One of the carcasses measured 4.3m (14ft) and the other 18ft. They can grow to 50ft long. They are the largest bony fish in the world. These were rare sightings since they live at the bottom of the oceans and when seen Japanese folklore believes them to be predictors of earthquakes. tells us the neat news that:

Hurricane season in the Atlantic begins June 1st and ends November 30th. The Eastern Pacific hurricane season begins May 15th and also ends November 30th. So it’s a wrap. No more hurricanes for the Eastern Pacific for a while.

There are also no imminent Cyclone alerts.

Volcanoes continue to be monitored as above, but no sign of threats to the climate as with Krakatoa.

The jet stream continues to be a major factor as it sweeps south of where it should be,bringing wind and rain, but nothing too extreme.

And today, 30th November, a welcome headline on a topic run on earlier blogs:

“Gloucestershire badger cull to end as targets missed” Sanity prevails at long last after 708 badgers were killed in the county, 942 fewer than the target of 1,650. The idea went against scientific advice and the killers could not carry out what they promised. 708 badgers died needlessly and the problem of TB in cattle has likely been worsened.


About borderslynn

Retired, living in the Scottish Borders after living most of my life in cities in England. I can now indulge my interest in all aspects of living close to nature in a wild landscape. I live on what was once the Iapetus Ocean which took millions of years to travel from the Southern Hemisphere to here in the Northern Hemisphere. That set me thinking and questioning and seeking answers.
