This winter, the polar vortex winds have stayed consistently stronger than average, corresponding to anomalously low atmospheric thickness over the Arctic (and generally warmer than averaged ...

A detailed analysis of polar vortex collapse mechanisms and how they relate to occasional North American cold outbreaks. Based on recent meteorological studies and stratospheric data, the video ...

“The polar vortex has been particularly strong and stable the past few weeks. That has kept the coldest of Arctic air largely confined to the North Pole,” says Mike Bettes, meteorologist with ...

The Arctic polar vortex is a circle of strong, cold winds that picks up every winter over the North Pole. The vortex is always present, but it strengthens in the winter due to a redistribution of ...

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.

"A polar vortex is simply that: a vortex that originates over the polar regions," according to AccuWeather meteorologist Bernie Rayno. "Because it starts over the polar regions, it has arctic air.

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.
