Wandering polar vortex may cause a wild, snowy winter

Wandering polar vortex may cause a wild, snowy winter

High above the North Pole, the polar vortex, a fast-spinning whirl of frigid air, is doing a weird shimmy that may soon bring cold and snowy weather to the Eastern U.S., Northern Europe and East Asia for weeks on end, meteorologists say.

While it's not unusual for the polar vortex to act up, this particular reconfiguration — wandering around and possibly splitting in two — may be tied to climate change in the rapidly warming Arctic, said Judah Cohen, director of seasonal forecasting at Atmospheric and Environmental Research in Massachusetts, part of Verisk Analytics, a risk-assessment company.

"Expect a more wintery back-half of winter here in the Eastern U.S. than what we had in the first half," Cohen told Live Science.

The Arctic is heating up faster than any other region in the world. As a result, sea-ice cover there is shrinking — in September 2020 and December 2020, the Arctic sea-ice cover shrunk to its second-lowest and third-lowest minimum on record for those months, respectively, according to the National Snow and Ice Data Center.

The warmer-than-usual temperatures in the Arctic are likely throwing the polar vortex out of whack, Cohen said. The polar vortex is a vast area of low pressure that sits high above the Arctic in the stratosphere — the layer above the troposphere, the lowest layer of Earth's atmosphere where most weather conditions happen. This low-pressure system is usually filled with cold, swirling air. During the winter, a jet stream of air that keeps the polar vortex in place sometimes weakens, allowing the vortex's chilly air to extend southward.

*********************************************

Here is more scientific nonsense, apparently global warming is going to cause a split in the polar vortex and freeze us all, if you can believe it. Notice how they have an explanation no matter what happens with the weather.

The explanation sounds better to me than some oaf who knows nothing deciding that he knows better.

And notice too, we all also notice YOU have no explanation for the weather anomalies  we've had for the last couple of decades.   You and the other nay-sayers to science will go on blithely believing that no amount of filth we pour in our water and spew into the atmosphere  will have any consequences.  :rolleyes:

Guess they'd like to go back to good old days when rivers were catching on fire...

Problem people think climate change is something new!

Just ask the ancient Egyptian how fast it happened before.

Guess the sun god Ra cursed them with global warming because not enough temples were built.

 

Fast climate change happened here a few hundred years ago in the west when an unusual wet period occurred and settlers thought that was NORMAL and people today still think it is.  Now it's simply reverting back.  Think huge cactus grows in a swamp? :wacko:

Put yourself into the shoes of a Medieval peasant farmer enjoying that long warm period then virtually overnight (a decade) the Little Ice Age struck.

The power of nature NOT man will determine how the Earth's climate will progress and any futile attempt to change it will fail. Shut down everything and nothing will change.

Maybe it will take another Tambora eruption to bring man to his senses.
