After a winter storm this weekend, the polar vortex will return, bringing subzero temperatures to around 80 million people from Montana to Maine and potentially as far south as northern Texas.

While scientists say that there is not evidence that extreme cold is becoming more frequent or intense, a growing body of research is finding that rising temperatures in the Arctic are weakening ...

“These events never happen over the Antarctic,” says Aditi Sheshadri, an atmospheric scientist at Stanford University. And the absence of these polar vortex disturbances in the Southern ...

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 ...

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

A big reason is we have another lobe of the Polar Vortex that is going to shift south into far southern Canada. This lobe of the vortex will drive very cold air into Michigan Sunday into the first ...

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?

Hello, readers! Let’s talk about a term that’s been used, and often misused, in the media recently: the polar vortex. The ...

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 ...

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 ...

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