Recent Press Highlights Changes in Arctic Atmosphere Circulation

January 27, 2011

In recent press, notably the New York Times, Arctic atmosphere circulation has been a hot topic.  PMEL's Dr. Jim Overland explains that the Polar Vortex, a ring of winds circling the North Pole and providing a fence keeping cold air north, has broken down for the second year in a row. This breakdown allows cold air to spill south, affecting the U.S. East Coast and other regions.
