Type II polar stratospheric clouds (PSCs) are known as one of the most beautiful cloud types in Earth's repertoire, appearing above the Arctic and Antarctic as softly glowing whisps with a ...

A sudden stratospheric warming event reversed the winds that make up the northern polar vortex on March 9. A new animation ...

Caption This cloud in the stratosphere over Titan's north pole (left) is similar to Earth's polar stratospheric clouds (right). NASA scientists found that Titan's cloud contains methane ice, which ...

A polar vortex collapse occurs when air in the stratosphere heats up significantly, displacing the vortex from its normal position at the poles and possibly moving it over the U.S. A polar vortex ...

When the polar vortex collapsed in the middle of March, the planet's weather patterns were redrawn. That could mean snow for ...

February 2022 was also characterized by an extremely strong stratospheric polar vortex—a large spinning mass of cold air in ...

The polar vortex is an area of low pressure and cold air circulating around the poles in the stratosphere — a layer in the atmosphere hovering between 7.5 and 31 miles (12 and 50 kilometers ...

The stratospheric weather event could see a warming event develop over the next two weeks, “leading to a collapse of the polar vortex”. Daniel Adamson of MetDesk told the Guardian ...
