The polar vortex is a circular weather pattern in the Arctic that typically holds back extreme cold. Occasionally, it can break and push frigid air into the U.S. This week marks the 10th polar vortex event, causing severe cold temperatures across the Northern and Central Plains. Wind chills could drop to minus 60°F in North Dakota. Experts note that disruptions in the polar vortex are becoming more frequent due to climate change, linking a warmer Arctic to increased atmospheric energy driving these weather changes.
The term polar vortex refers to the upper air weather pattern in the Arctic that can influence extreme weather events in the U.S. and beyond.
Incidents of polar vortex disruptions are increasing, suggesting a relationship to global warming, as warmer Arctic conditions energize weather patterns.
