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 ...

“The polar vortex is often considered a part of that mechanism,” Butler wrote in her email. The 2018 paper that found a link between weaker vortices and severe winter weather, ...

The polar vortex is essentially a large area of low pressure and cold air surrounding both of Earth’s poles. It constantly sits over the poles but expands in the winter.

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 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 vortex is essentially an area of low pressure in the upper layers of the atmosphere over the polar region. This vortex consists of powerful westerly winds in the stratosphere, about 10 to 30 ...

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 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 ...

These polar vortex stretches are happening more frequently as the world — and especially the Arctic — warms, a 2021 paper published in the journal Science, also co-authored by Cohen, demonstrated.

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 ...
