Polar Vortex brings near record cold temps this winter

A whirlpool of frigid, dense air known as a "polar vortex" descended Monday into much of the United States, pummelling parts of the country with a dangerous cold that could break decades-old records with wind chill warnings stretching from Montana to Alabama.

For a big chunk of the Midwest, the extremely cold temperatures were moving in behind another winter wallop: more than 30 centimetres of snow and high winds that made travelling treacherous. Officials closed schools in cities including Chicago, St. Louis and Milwaukee and warned residents to stay indoors and avoid the frigid cold altogether.

The forecast is extreme: 35 C in Fargo, N. D., 29 C in Madison, Wis. and 27 C in Minneapolis, Indianapolis and Chicago. Wind chills could drop into the 40s and 50s.

In Indianapolis, Ind., Mayor Greg Ballard issued a "code red" order last night making it illegal for non-emergency vehicles to be on the city's streets unless they were seeking shelter. The order was expected to last until midday Monday as snow-clearing continued in the frigid temperatures. The last time the city issued such a travel warning was during the 1978 blizzard.

Elsewhere in Indiana, state police closed a 142-km stretch of I-65 on Sunday when conditions became too hazardous, Indianapolis media reported.

"It's just a dangerous cold," said National Weather Service meteorologist Butch Dye in Missouri.

It hasn't been this cold for almost two decades in many parts of the country. Frostbite and hypothermia can set in quickly at those temperatures.

Lorna West, a 43-year-old student and consultant from Columbus, Ohio, said she doesn't believe people unaccustomed to such weather are ready for what's coming.

A Chicago native, she said thermal underwear, lots of layers and "Eskimo coats" with zipped hoods to block the wind were the norm growing up.

Wifey's school lost power this morning.

TDSB forcing them to teach in the dark.

It's going to dip down even further tomorrow before it pulls back up for the weekend.

Hope she's following board guidelines and teaching climate change is being caused by man. They could call it Earth Day since the lights are off.

Environment Canada's David Phillips told the BBC the rapid temperature drop expected - about 24 degrees C in 24 hours in cities such as Toronto - means residents could be driving or walking on roads that are "like a rink of ice".


Some parts of Canada could see as much as 60cm (23in) of snow over just a few days, Phillips said.

Is it a side effect of global warming and should we expect more events like this?

This is a hotly researched topic. In short, yes, it could be. It seems counterintuitive that global warming could cause significant cold snaps like this one, but some research shows that it could. We know that different types of extreme weather can result from the overall warming of the planet, melting of the Arctic Sea ice, etc. This includes extreme distortions of the jet stream, which can cause heat waves in summer and cold snaps in winter.

It,s normally called a trough or arctic low but vortex sounds way cooler on the news.

PS they happen every winter.

It is just weather. If the temperature went above average then it would be AGW.

It is a vortex of global warming at serious minus temperatures.
Breaking all kinds of cold temperature records and still people
are chanting the hymn Climate change and global warming.
The mantra for this stuff is this global warming and climate
change means you must do what you can for the planet.What
can we do?
Buy new light bulbs
buy a fridge
a new car would be nice
a new furnace too
its all for the planet what can you do.

we are being hosed through the nose by innocent people and
those with a big ticket agenda.
I have come to this conclusion the corporations have duped the
greenies into believing their own propaganda and are about to
rake in billions at everyone's expense.
Oh and when the summer comes they'll sell you a new air conditioner
one that is green stay tuned. It just makes me want to go out and run
my truck for an hour.

I've been saying that for years and have offered up proof but the truth of the matter is it doesn't matter, the cerebral damage has ben done.

Polar Vortex in U.S. May be Example of Global Warming

While the ongoing cold snap is breaking records from Minnesota to Florida, it will not go down in history as the most significant Arctic outbreak in U.S. history, not even by a longshot. Scientists said the deep freeze gripping the U.S. does not indicate a halt or reversal in global warming trends, either. In fact, it may be a counterintuitive example of global warming in action.

Researchers told Climate Central that the weather pattern driving the extreme cold into the U.S. — with a weaker polar vortex moving around the Arctic like a slowing spinning top, eventually falling over and blowing open the door to the Arctic freezer — fits with other recently observed instances of unusual fall and wintertime jet stream configurations.

Such weather patterns, which can feature relatively mild conditions in the Arctic at the same time dangerously cold conditions exist in vast parts of the lower 48, may be tied to the rapid warming and loss of sea ice in the Arctic due, in part, to manmade climate change.

Arctic warming is altering the heat balance between the North Pole and the equator, which is what drives the strong current of upper level winds in the northern hemisphere commonly known as the jet stream. Some studies show that if that balance is altered then some types of extreme weather events become more likely to occur.

During the past week, while much of North America has seen frigid temperatures, weather maps show a strip of orange and red hues, indicating above-average temperatures, across parts of the Arctic, Scandinavia, Europe and Asia.

“I do think that what has happened in the North America, including the U.S. this winter, so far fits under the paradigm of ‘warm Arctic cold continents,’ ” Judah Cohen, a climate forecaster at Atmospheric and Environmental Research in Massachussetts, said in an email.

The warmth in the Arctic made headlines in early December when the temperature hit 39F in Prudhoe Bay, north of the Arctic Circle. That was the highest December temperature on record there since at least 1968, according to the National Weather Service.

Cohen published a study in September that found this Arctic paradox pattern has become common in years with low fall sea ice cover and rapidly advancing fall snow cover across parts of Asia, and that there is a likely link between the trends. The paper found the pattern was observed during the winter of 2012-2013, following the lowest fall sea ice extent on record in September 2012.

The Arctic has had a mild winter so far, in part because of an area of high pressure in the North Pacific Ocean that has blocked the flow of weather systems like a stop sign at an intersection, forcing the jet stream northward over western Canada, and then back down to the southeast across the U.S. That favors episodic outbreaks of cold air in the East, Cohen said, but not extended cold.

Jennifer Francis, a researcher at Rutgers University and the most prominent proponent of the hypothesis that Arctic warming is altering the jet stream around the Northern Hemisphere, told Climate Central that while the cold snap is brief in duration, it fits with patterns observed this year and in other recent years.

“The persistence of the pattern seems consistent with an amplified jet stream configuration that we expect to see occur more frequently as the Arctic continues to warm disproportionately,” Francis said in an email.

Regardless of the strength of the Arctic connection, global average temperature trends tell a clear and compelling story of a warming planet, which one short-lived cold streak is not going to alter.

Since 1970, winters have been warming rapidly in the majority of the lower 48 states. The five most rapidly warming states, with winter average temperatures increasing by more than 4F, were Minnesota, North Dakota, South Dakota, Vermont, and Wisconsin, according to a 2013 Climate Central analysis. Many of those same states are bearing the brunt of the ongoing cold outbreak, but had the climate not warmed so much during the past few decades, it’s possible that this event would be even colder in those areas.

November, the most recent month for which global data is available, was the warmest such month on record, all but guaranteeing that 2013 will go down on record as one of the top 10 warmest years, if not in the top 5. In Australia, 2013 was the continent’s hottest year on record.

Russia had its warmest November since records began there in 1891, with some parts of the country, including Siberia and the Arctic islands in the Kara Sea, seeing temperatures that were more than 14F above the typical monthly average. In contrast, not a single region of the world was record cold for the month.

November also brought the string of consecutive above-average months on the planet to 345, with it being the 37th straight November with above-average temperatures compared to the 20th century average. That means that anyone younger than 28 has never experienced a colder-than-average month, globally speaking. The last below-average November global temperature was in November 1976, and the last below-average global temperature for any month was February 1985, according to the National Oceanic and Atmospheric Administration.

As unusual as the current cold is for the U.S., the global picture shows that January is not on course to break that 28-year warm streak, either. Even the U.S. may end up having a warmer-than-average month, if the latest outlooks prove correct.

Calling an Arctic low or Arctic trough a Polar Vortex and blaming it on global warming is f*cking pathetic.

Some of us in Canada get them 10 times a winter and are nothing new.

Petros... what else could they do? The congregation is looking up to their Pastors looking for answers to this dreaded, frigid, record breaking winter.
