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 ...

The main reason for the polar vortex to slow down is disturbances from the surface. Weather over the Amundsen Sea near Antarctica in the South Pacific is an important source of these disturbances.

Scientists are becoming concerned about the possible long-term effects of Antarctica's record-breaking hot wave on both the continent and the world climate. Temperatures in some areas of ...

But when the southern polar vortex gets disrupted, it releases cold air trapped over Antarctica and sends bursts of it farther north. This also leaves the door open for air to rush down from the ...

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 ...

Travelers visiting Antarctica have helped scientists at UC San Diego's Scripps Institution of Oceanography learn more about ...

On Wednesday, Chicago will be colder than parts of Antarctica, Alaska and the North Pole. The Windy City's "high" temperature on Wednesday should be around 10 below zero, while the overnight low ...

A second polar vortex swirls over Antarctica. Typically that cold air is contained by a fast moving current of air known as the jet stream. The speed of that current is typically propelled by the ...

The polar vortex is a circular weather pattern that sits above Antarctica, which usually keeps a ring of icy weather contained to the continent. But when warmer than average air temperatures creep ...
