Research has found that rising temperatures in the Arctic are weakening weather systems that normally trap the cold around ...

How the Polar Vortex Can Bring Arctic Blasts to the U.S. Vast weather patterns can carry blasts of frigid air far from the ...

One of the key players in these dramatic shifts is something called the polar vortex. The polar vortex is a massive area of cold air located high in the atmosphere, typically spinning over the ...

A second polar vortex swirls over Antarctica. Typically that cold air is contained by a fast moving current of air known as the jet stream. The speed of that current is typically propelled by the ...

But what is it? Definition: The polar vortex is a flow of wind aloft that is always present above the cold, North and South Pole areas. In the Northern Hemisphere this results in a counter ...

The cold temperatures are coming from a not uncommon expansion in the Polar Vortex, which are counter-clockwise rotating air currents that typically hang over the Arctic.

It's a term you hear every couple of winters, when we get stuck in the coldest of cold patterns – polar vortex. But what exactly is it and how does it impact our weather? The polar vortex is ...

North and South Pole, is very cold. So that's your polar vortex. That's what the polar vortex is," explained KARE 11 meteorologist Jamie Kagol. So what does that have to do with Minnesota?

Abnormal weather events and severe winter storms could be caused by a disrupted polar vortex. Find out here how the polar ...

While jet streams are air patterns, the Gulf Stream is an ocean pattern that also has an impact on weather.

At the same time we go into a touch milder southwest flow, the polar vortex will still be churning away over northeast Canada. I don’t expect a full onslaught of the polar vortex to shift south ...
