A major disruption to the Arctic polar vortex has bumped the ring of wind that circles the North Pole off its perch and towards Europe, a new animation shows. The migration could trigger colder ...

The deadly cold front was tied to a misshapen Arctic polar vortex. In the winter, this mass of air swirling above the North Pole can push deadly winter weather into southern latitudes. Photograph ...

The polar vortex is like a giant, swirling pool of super-cold air in the upper atmosphere over the North Pole. Imagine it like a children's spinning top. When the top is spinning fast and steady ...

The polar vortex usually keeps cold Arctic air confined above the North Pole, but experts believe it is starting to shift and ...

It is a normal pattern that is stronger in the winter and keeps some of the coldest weather bottled up near the North Pole. But at times some of the vortex can break off or move south, bringing ...

Much of the country will be hit with extreme low temperatures over the next week as a polar vortex sends cold air down from the North Pole. Real feel temperatures throughout the northeast ...

Such plunges occur when the air currents that keep frigid air over the North Pole — the polar vortex — weaken, and the freezing arctic air slips south and pushes the vortex down with it.

According to the National Weather Service (NWS), the Arctic polar vortex is a powerful band of west-to-east winds that develops in the stratosphere, about 10 to 30 miles above the North Pole ...

A polar vortex, a massive pocket of frigid air that swirls in place over the North Pole, is expected to spill out and push Arctic temps south. The New Jersey-Philadelphia region should feel the ...

The polar vortex is a region of very strong winds that form a circle around the North Pole. The vortex is located in the stratosphere, the layer above the troposphere (the troposphere is where we ...

A lobe of the Polar Vortex is going to swing through Ontario just north of Michigan. The upper-air forecast gives us an easy look at this strong winter player. The general meaning of the Polar ...

Sometimes during the northern hemisphere winter months, that belt near the North Pole can get a bit wavier and extend southward toward the U.S. When a chunk of the polar vortex dislodges from the ...
