Animation of surface air temperature and geopotential height during February 2023 cold outbreak over US

Published: March 8, 2023

Animation showing surface air temperature maps with geopotential height contours (in km at the 200 hPa pressure surface) overlaid over North America and the Arctic from February 17th to 26th, 2023, showing the breaking polar vortex and extremely cold air plunging into the US.
