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.
NOAA Satellites Capture the Chilling Impact of Polar Vortex
Jan 6, 2025 · The polar vortex is a stream of cold air that normally circles the Arctic. Normally contained by a strong jet stream, this ring of frigid arctic air can become unstable when the jet stream weakens, allowing it to spill southward. During the week of Jan. 6, 2025, this phenomenon brought below-freezing temperatures to much of the United States ...
