How the Polar Vortex Can Bring Arctic Blasts to the U.S. Vast weather patterns can carry blasts of frigid air far from the polar regions—here’s how it works ...

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

two bands of fast-moving air – the polar jet stream and the stratospheric polar vortex – sometimes tango together to influence weather in the northern hemisphere. As the Arctic continues ...

Winter in the CSRA is usually mild overall, but every now and then, we get a taste of true Arctic air. If you’ve ever ...

The vortex is essentially an area of low pressure in the upper layers of the atmosphere over the polar region up north. This ...

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 ...

frigid air pushes southward toward the U.S. What's the difference between an Arctic air mass and the polar vortex? Arctic air masses originate over the Arctic or Antarctic regions and are very cold.

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?

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 ...

The coldest weather of the season to date will be due to a phenomenon called a polar vortex, an upper-level jet stream that typically circulates around the North Pole and South Pole, but can push ...
