When the Polar Vortex is in a weakened state, a jet stream wobble sending polar air into the mid-latitudes becomes more ...

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 ...

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 ...

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

Winter in the CSRA is usually mild overall, but every now and then, we get a taste of true Arctic air. If you’ve ever ...

two bands of fast-moving air – the polar jet stream and the stratospheric polar vortex – sometimes tango together to influence weather in the northern hemisphere. As the Arctic continues ...

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 ...

The vortex is essentially an area of low pressure in the upper layers of the atmosphere over the polar region up north. This ...

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 ...
