Polar vortex to blast US with life-threatening cold next week: …
4 days ago · A major cold blast is in store for more than 30 states as a widespread arctic air outbreak will send nearly every American east of the Rockies into a deep freeze. This will be due to a polar vortex, an area of strong winds that encircle the Arctic and typically keeps the coldest air locked near ...
Another blast of Arctic air: this time, with a stretched but strong ...
4 days ago · Normally, if the polar vortex is communicating with the surface, which it finally has been in the last couple of days, a strong polar vortex would be associated with persistent warmth over much of Europe, Asia, and the eastern US. (A strong polar vortex is usually associated with a northward shifted jet stream that keeps the coldest air corralled over the pole.)
Polar vortex-driven Arctic blast to yield historic southern snow
11 hours ago · Both researchers said this interaction is likely to be more short-lived than what happened during the infamous polar vortex winter of 2013-2014. Over longer timescales, studies suggest polar vortex shifts may be more likely due to human-caused climate change, but this is an area of active research.

Why more frequent cold blasts could be coming from global …
Jan 7, 2025 · When the polar vortex stretches it can either bring that cold air south to the United States or toward Asia, said Cohen, an expert in winter weather. Other times, when something called sudden stratospheric warming happens, the polar vortex moves away from the Arctic and comes south or even splits. That’s not the case this time, Cohen said.
Arctic blast tied to polar vortex puts U.S., Europe in deep freeze
Jan 2, 2025 · When these strong winds slacken, parts of the polar vortex can detach and meander southward, bringing ultra-cold air to southern Canada, the U.S. and Europe. This occurred back in the winter of 2013-14 , but this new event is distinct.
Understanding the Arctic polar vortex - NOAA Climate.gov
Mar 5, 2021 · The Arctic polar vortex is a band of strong westerly winds that forms in the stratosphere between about 10 and 30 miles above the North Pole every winter. The winds enclose a large pool of extremely cold air.
