When the polar vortex stretches, North America feels the chill. New research reveals some of the stratospheric patterns controlling these cold snaps.

The Polar Vortex,an atmospheric phenomenon that shapes our winter weather,has been gaining attention as it undergoes changes ...

Three factors are combining to increase the likelihood of a weaker polar vortex this winter, the website reports. And a ...

We've mentioned the polar vortex several times in recent days. We've said, for instance, that it's "a low pressure system that's usually whirling around the North Pole but has weakened and come ...

Despite a warming climate, bone-chilling winter cold can grip parts of the U.S. In a study appearing in Science Advances, ...

The polar vortex – everyone's favorite wintertime whipping boy – is actually a gigantic, circular area of cold air high up in the atmosphere that typically spins over the North Pole ...

The polar vortex split will help cause temperatures to plummet and potentially set the stage for some snowstorms. A recent strong "sudden stratospheric warming" event has caused the vortex to weaken.

The polar vortex is a broad region of freezing air that lives above the North Pole. It can make for frigid weather when the jet stream, which usually holds it in place, bends and lets that cold ...

“The polar vortex is a core of extremely cold air that typically remains near the poles,” explains Spectrum News NY 1’s Chief Meteorologist John Davitt.. “During the winter, shifts in the ...

The term “polar vortex” dates back to at least 1853, but names for the phenomenon shifted when scientists began to study it in earnest in the 20th century.

The polar vortex, as its scary name suggests, is a circulation of strong, upper-level winds that normally surround the northern pole, moving in a counterclockwise direction — a polar low ...
