Antarctica’s polar vortex could be about to split in two for the first time in more than 20 years after a series of sudden spikes in stratospheric temperatures. If that happens, it could lead to ...

The Antarctic ozone hole usually starts forming in early August, but rare warming events and a strangely elongated polar vortex this year may have delayed its arrival. When you purchase through ...

The vortex is constantly spinning in a counter-clockwise direction around the North Pole. Its counterpart in the southern hemisphere is the Antarctic polar vortex. During the summer months in the ...

Unlike the Arctic, where sudden stratospheric warming events are almost annual, the Southern Hemisphere's polar vortex is typically more stable. The Antarctic troposphere also saw unusual weather ...

"High temperatures this week at the U.S. McMurdo Antarctic research station are forecast to be in the teens and low 20s (above zero), easily warmer than the highs parts of the Midwest will see ...

Arctic ice has seen what scientists found to be “irreversible” thinning since 2007; Antarctic sea ice hit ... much of the public to the polar vortex. The phrase refers to a naturally occurring ...

frigid air pushes southward toward the U.S. What's the difference between an Arctic air mass and the polar vortex? Arctic air masses originate over the Arctic or Antarctic regions and are very cold.

There is a sudden warming about to happen high up in the atmosphere. This warming will affect the Polar Vortex. The Polar Vortex is a fast-spinning circular motion usually located about 50,000 ...
