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.
