But on occasion it can cause the vortex to split entirely in two. That, meteorologists warn, could lead to a cold spell that lasts weeks. “The polar vortex has been particularly strong and ...

A split in the polar vortex can give rise to both sudden and delayed effects, much of which involves declining temperatures and extreme winter weather in the Eastern US along with Northern and ...

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.

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.

Researchers note that February was also characterised by an extremely strong stratospheric polar vortex - a large spinning mass of cold air in the stratosphere around 15 miles above the Arctic ...

Scientists say a "swirling polar vortex" miles above the Earth caused three deadly storms in the UK and Ireland, which brought severe flooding and record wind speeds. Four people lost their lives ...
