What we call the polar vortex -- a spin in the atmosphere -- can't actually be felt in the U.S. or anywhere on Earth. It doesnâ t ice over too often ...

One way to track the polar vortex is through potential vorticity, which describes the amount of rotational energy, or "spin," in a parcel of air. This animation shows daily potential vorticity in ...

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 is a low-pressure system of cold air that swirls above both of Earth’s poles. Over the North Pole, the wind flows counterclockwise in the stratosphere around 16 to 50 kilometers ...

"Polar vortex" headlines have grabbed attention in recent winters, but such atmospheric phenomena aren't out of the ordinary, a local meteorologist tells Axios. Why it matters: Weather like this ...

The polar vortex has taken on an unexpected pattern this winter - one that’s made part of the United States the most unusually cold place on the planet, at least so far this year.

Think of the polar vortex as a huge cylinder of low pressure and cold air that hovers over the North Pole and high into the atmosphere during the winter. When the polar vortex is strong, the cold ...

Weather analysts are divided over the polar vortex’s influence on weather and what that means for the rest of this year’s winter. The polar vortex is an area of low pressure and cold air that ...

When high pressure builds into the Arctic Circle, the polar vortex is pushed south and away from the pole, giving it an opportunity to sink into the United States.

This week, parts of the U.S. are experiencing the 10th and coldest polar vortex event this season. Weather forces in the Arctic are combining to push the chilly air into the U.S. and Europe.
