A strong, stable vortex is like a skater spinning with their arms tucked closely in, holding in an area of cold air over the Arctic. But when there’s a wobble in the rotation, winds in the vortex can ...

Research has found that rising temperatures in the Arctic are weakening weather systems that normally trap the cold around ...

Understanding the Polar Vortex The polar vortex is like a massive whirlpool of frigid air moving around our planet's poles. Think of it as a barrier that, when strong, keeps icy polar air trapped up ...

Abnormal weather events and severe winter storms could be caused by a disrupted polar vortex. Find out here how the polar ...

Here's how the polar vortex, and climate change, influence extremely cold winter weather in the US. Intense snowy wintry weather in the US has been fuelled by activity of the polar vortex ...

A strong polar vortex in the stratosphere has brought subzero temperatures to the Midwest, Mid-Atlantic and deep into the South.

But some emerging science suggests that, generally, the polar vortex could be changing as a result of global warming, possibly causing more cold extremes in North America. Warming temperatures at ...

The University of Wisconsin-Madison faced a frigid start to the semester, with the polar vortex expected to bring more icy ...

The polar vortex can be disrupted by factors such as natural turbulence, high-latitude ocean warming, sea ice loss, sudden atmospheric warming, planetary waves and climate change, says the ...
