Meteorologists blame freak Arctic weather phenomenon for US snowstorms

Meteorologists say a freak weather phenomenon over the Arctic is responsible for the storms which have dumped record amounts of snow on the United States East Coast this winter.

The phenomenon, known as the North Atlantic Oscillation, is pushing frigid winds from the North Pole across the Atlantic, where they are colliding with the warm, moisture-laden air over the southern US. Jet streams, a belt of winds aloft at about 18,000 feet, are then carrying the cold air north-west, where the moisture is falling as snow.

In normal winters, the air mass above the Arctic is surrounded by a circular vortex of wind currents - a kind of fence that keeps in the frigid polar air. This condition, which meteorologists call the North Atlantic Oscillation's Positive Phase, ensures both sides of the Atlantic have relatively mild winters.

A seasonal canine illness seems to be affecting dogs in certain parts of England.

The disease which was first noted in the autumn of 2009, has affected 19 dogs in Warwickshire, Nottinghamshire and Lincolnshire in the past two years, and 12 died. More fell ill in 2010, which prompted the Animal Health Trust to carry out its research into this illness, the most common symptoms being sickness, diarrhoea and lethargy.

Britons going cold on global warming: Number of climate change sceptics doubles in four years

© Press AssociationChilly outlook: The ice cold winters of recent years has seen the number of climate change sceptics more than double
The number of climate change sceptics has almost doubled in four years, official research showed yesterday.

A quarter of Britons are unconvinced that the world is warming following successive freezing winters and a series of scandals over the credibility of climate science.

The figures suggest that a growing proportion of the public do not share the belief of all three major political parties and Whitehall - that climate change is a major and urgent challenge requiring radical and expensive policies.

The survey, carried out by the Office for National Statistics, has plotted levels of acceptance of the theory of man-made global warming since 2006.

In that year it found that 87 per cent of people were at least 'fairly convinced' that climate change was happening.

Comment: The statement "There is also an increasing reluctance to take personal steps to tackle climate change" seems to indicate that we can turn the ship around when in fact there is little we can do or could have done. From all appearances we are experiencing a cyclic global cooling period.

Bloom in the Ross Sea

Every southern spring and summer, after the Sun has risen into its 24-hour circuit around the skies of Antarctica, the Ross Sea bursts with life. Floating, microscopic plants, known as phytoplankton, soak up the sunlight and the nutrients stirring in the Southern Ocean and grow into prodigious blooms. Those blooms become a great banquet for krill, fish, penguins, whales, and other marine species who carve out a living in the cool waters of the far south.

This true-color image captures such a bloom in the Ross Sea on January 22, 2011, as viewed by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite. Bright greens of plant-life have replaced the deep blues of open ocean water.

The Ross Sea is a relatively shallow bay in the Antarctic coastline and due south from New Zealand. As the spring weather thaws the sea ice around Antarctica, areas of open water surrounded by ice - polynyas - open up on the continental shelf. In this open water, sunlight provides the fuel and various current systems provide nutrients from deeper waters to form blooms that can stretch 100 to 200 kilometers (60 to 120 miles). These blooms are among the largest in extent and abundance in the world.

The Long Winter of 2010-2011

Image
For New Yorkers and those in my part of New Jersey across the river, snow has fallen eight times since December 14, an average of once every five days, 56.1 inches in Central Park as of Jan 27th, and people are, shall we say, taking notice?

Along with the snow come power outages, disrupted bus schedules, air travel delays, commuting by car becomes an auto body repair business bonanza, schools shut their doors, and some people die from weather-related accidents or just from trying to shovel the snow from the driveway.

Having battled the "global warming" hoax since it was first perpetrated in the late 1980s, I have had the good fortune to make friends with many of the world's top meteorologists and climatologists who joined in the long effort to educate people to the fact that there never was a rapid rise in the planet's overall temperatures.

Even so, some mainstream media news outlets have continued to file stories incredulously blaming the winter snow storms on "global warming." The hoax for too many media folk has long since become a religion in which blind faith replaces the objective fact obvious to everyone. It is cold. There is snow. Lots of it.

Indeed, the Earth has been in a cooling cycle since around 1998 as verified by meteorological satellite and other data. Piers Corbyn, an astrophysicist and leading forecaster, said "We're now headed for a Maunder minimum of very low solar activity. The globe will be much cooler until about 2035, so there will be a lot more of these cold winters in Europe and the USA."

Winter Storm: East Coast Battles Another Record Breaking Snowstorm

The East Coast is gradually digging out from the record-breaking snowstorm that battered the East Coast Wednesday night, causing power outages and leaving travelers and commuters stranded.

It was the sixth snowstorm to slam into the region in the last 30 days.

Overnight, thundersnow -- the rare phenomenon in which thunder and lightning strike even in the dead of winter -- shocked residents in Sellersville, Pennsylvania, and as far away as central New Jersey. Philadelphia was hit with 17 inches of snow, totals in the Washington D.C. area ranged from 3 to 7 inches and, according to the National Weather Service, parts of New Jersey had to dig out from 19 inches.

A Day of Night-Shining Clouds

Mesospheric Clouds

Scientists have a good reason to track noctilucent or polar mesospheric clouds: they are a pretty good gauge of even the tiniest changes in the atmosphere. These "night-shining clouds," as they are sometimes called, are thin, wavy ice clouds that form at very high altitudes and reflect sunlight long after the Sun has dropped below the horizon.

To look for changes in the atmosphere, scientist Matthew DeLand (of Science Systems and Applications Inc. and NASA's Goddard Space Flight Center) has been monitoring polar mesospheric clouds with instruments that were actually designed to study ozone, including the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite. OMI provides more detailed and frequent observations than previous instruments, giving DeLand a way to refine his previous measurements of a long-term trend towards more and brighter noctilucent clouds linked to rising greenhouse gases.

These images show OMI measurements of polar mesospheric clouds on July 10, 2007. The clouds, detectable because they are the only things that reflect light in this part of the atmosphere, are shown in white and pink. The Aura satellite travels in a polar orbit, circling from south to north as the Earth turns beneath it. As a result, the satellite gets several opportunities to image the poles every day. This series of images shows the clouds over six consecutive orbits between 7:16 and 15:52 Universal Time. Throughout the day, a wide area of polar mesospheric clouds developed over northern Greenland and Canada, peaking around 10:30 UTC (the third orbit).

V-Topped Light Pillars

Light pillars are a common sight around cities in winter. Urban lights bounce off ice crystals in the air, producing tall luminous columns sometimes mistaken for auroras. But the light pillars Mike Hollingshead saw last night near a corn mill in Nebraska were decidely uncommon. "They had V-shaped tops," he explains, "and some of the Vs were nested." Here is what he saw:

"These light pillars are not just rare, they are exceptional!" declares atmospheric optics expert Les Cowley. "Ordinary pillars are produced by plate-shaped ice crystals roughly half way between you and the light source. These ones are different. Their rarely seen flared tops show that they were made by column-shaped crystals drifting slowly downwards and aligned horizontal by air resistance."
