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 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 is a counterclockwise spinning area near the top of the atmosphere and usually centered near the North Pole region. This fast spinning vortex is about 50,000 feet in the atmosphere.

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 ...

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 forms in the Arctic Circle in the winter months due to the lack of sunlight associated with the season. The division between frigid cold temperatures at the North Pole and warmer ...

The polar vortex spins anticlockwise around the North Pole with wind speeds of about 155mph (250km/h). There are two types of polar vortexes – tropospheric and stratospheric. The tropospheric ...

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.

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 ...
