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

“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 ...

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 ...

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 ...

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 ...

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

It looks like it could get even colder heading into next week. Within the last decade, the phrase 'polar vortex' has become popularized in the weather world. In fact, you may have heard it getting ...

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 ...

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.
