Several days with temperatures of 10-20 degrees below the historical average could be dangerous to plants and ruin outdoor ...

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.

The polar vortex is like a massive whirlpool of frigid air moving around our planet's poles. Think of it as a barrier that, when strong, keeps icy polar air trapped up north. This barrier is ...

The Polar Vortex's collapse will cause a major Arctic blast from central Canada into the Northeast United States, even if a progressive and dynamic weather pattern will persist across North ...

Devastating winter storms that led to deaths and power outages across the UK and Ireland were driven by an intense swirling vortex of winds miles above the Arctic, scientists have revealed.

South of the Arctic’s polar vortex is the jet stream, a river of west to east air that flows five to nine miles above ground, and helps keep the pole’s cold air confined to the Arctic.

Content continues below The Arctic Oscillation (AO) is another teleconnection that can serve as a good proxy for keeping track of the polar vortex. The AO tracks changes in the mid-levels of the ...

The polar vortex disruption occurs when warm winds breach the arctic — dragging cold air further south. The meteorologist said the disruption has brought along warmer weather to parts of New ...

Icy winds from the Arctic are bringing yet another spell of freezing weather to Scotland due to a phenomenon known as a polar vortex collapse, which is keeping more spring weather at bay.

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.

"The large polar vortex disruption from the ... tends to keep the coldest weather bottled up in the Arctic. However, a disruption in the vortex – known as "sudden stratospheric warming ...
