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 ...

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 ...

A polar vortex dipping down from Siberia is bringing a cold front with frigid temperatures to millions Americans. See maps of the arctic blast.

As we continue to warm moving into February, it appears latest trends suggest a classic "what goes up, must come down" type ...

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

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 ...

Sometimes, lobes of the polar vortex can separate and get stuck well to the south. Multiple studies have strengthened scientists’ understanding of the phenomena as a consequence of Arctic ...

With that idea there would be a warm push from the south. The warm push would hold the polar vortex in check and keep the true Arctic air even farther north. We still have plenty of winter weather ...

Imagine it as a giant, icy whirlpool far above the Earth, keeping frigid Arctic air contained near the pole. But here’s where things get interesting: the polar vortex’s behavior is closely ...

In the winter, the polar vortex helps keep frigid, Arctic air trapped in the Arctic Circle within the vortex. It acts as a barrier between the midlatitudes and the poles. However, at times the ...
