A major disruption headed for the Arctic polar vortex A sudden stratospheric warming event changed the winds The vortex is now pointing toward Europe instead of the ...

A sudden stratospheric warming event reversed the winds that make up the northern polar vortex on March 9. A new animation shows the vortex also moved away from the Arctic towards Europe.

An April cold snap is expected to bring unusually cold temperatures to the eastern half of the US next week. The cold snap could impact new spring vegetation and lead to frost in some areas.

The Polar Vortex in the upper atmosphere has disintegrated after the intense warming of the stratosphere in mid-March. Currently, its remains are traveling eastward across Canada to the United States.

Don't put away those winter coats just yet. An April cold snap is forecast for much of the eastern half of the U.S. early next week, forecasters said, with freezes likely across portions of the ...

A polar vortex is a large area of low-pressure and cold air that circulates around the Earth’s poles, typically confined to the Arctic or Antarctic regions. This swirling mass of frigid air is ...

The polar vortex is a low-pressure system of cold air that swirls above both of Earth’s poles. Over the North Pole, the wind flows counterclockwise in the stratosphere around 16 to 50 kilometers ...

The polar vortex slid toward Europe in recent weeks, ushering in cooler temperatures to portions of Canada A significant disruption to the polar vortex over far Northern Canada will keep the ...

A significant disruption to the polar vortex over far Northern Canada will keep the pattern’s influence locked in our neck of the woods like a houseguest overstaying their welcome. Even as the world ...

Researchers from the University of Leeds have found there was an extremely strong stratospheric polar vortex (SPV) – a large spinning mass of cold air in the stratosphere around 15 miles above ...
