When a polar vortex collapses, it's known as a Sudden Stratospheric Warming (SSW). This event, linked to cold winter weather, causes stratospheric temperatures to rise rapidly – up to 50°C in a ...

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 collapse occurs when the layer between 10 and 50km above Earth’s surface warms up to 50 degrees in just two days - known as sudden stratospheric warming (SSW).

A polar vortex collapse. Now, meteorologists are calling for another collapse in the middle of March, one that could plunge the U.S., Canada, and parts of Europe into a bitterly cold spell just ...

The most well-known cause is a weak polar vortex. The polar vortex is a compact area of low pressure parked in the poles. Credit: WMAZ ...

Wood said there are some similar characteristics to a polar vortex, "but it's not a slam dunk example." The jet stream did push in the cold air mass from northern Canada, like a polar vortex would ...

The polar vortex is area of fast-moving winds well above the Earth’s surface and the jet stream that circle the Arctic during the Northern Hemisphere’s coldest months. When it’s strong, it ...
