Understanding the Polar Vortex The polar vortex is like a massive whirlpool of frigid air moving around our planet's poles.

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

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

This stability helps keep the polar vortex — and all its bitterly cold air — locked up in the Arctic, far from places like the United States or Europe. However, when the jet stream weakens ...

It's a term you hear every couple of winters, when we get stuck in the coldest of cold patterns – polar vortex. But what exactly is it and how does it impact our weather? The polar vortex is ...

At the same time we go into a touch milder southwest flow, the polar vortex will still be churning away over northeast Canada. I don’t expect a full onslaught of the polar vortex to shift south ...

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

As the Artic is warming much faster than other parts of the planet, the temperature difference that helps maintain the polar vortex's stability is reduced, resulting in a weaker jet stream ...
