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 ...

How the Polar Vortex Can Bring Arctic Blasts to the U.S. Vast weather patterns can carry blasts of frigid air far from the polar regions—here’s how it works ...

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 ...

Current trend in heavy snowfall and bitterly cold temperatures is directly linked to a disruption to the polar vortex caused ...

A mass of air called the polar vortex has escaped the Arctic and plunged southward. Some scientists see the fingerprints of ...

Again, Cohen said, that’s explained by the polar vortex and climate change. As winters get warmer on average, the cold temperatures brought about by the polar vortex events essentially gets ...

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 ...

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

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 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 ...
