Punxsutawney Phil, the legendary weather-forecasting groundhog from Punxsutawney, PA, saw his shadow Sunday morning, thus ...

all that icy air stays tightly locked around the arctic, keeping the freezing temperatures up north. But just like when a top starts to slow down and wobble, the polar vortex can sometimes get out ...

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 ...

That just didn’t happen, so while the weather system was, technically, a polar vortex, it was really an arctic blast in a rail context. Regardless of what we call it, it’s history now and bullet ...

Extreme cold and snow smacked the Gulf Coast states this week, but the polar vortex may not be to blame.

The Polar Vortex is a large spinning area of cold air typically centered over the arctic. However, sometimes high pressure develops over the north pole. The Arctic Oscillation refers to wobbles ...

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 ...
