Polar Vortex Collapse Predicted to Trigger Severe Cold Across North America and Europe

Meteorologists warn of a second polar vortex disruption in 2025, potentially bringing extreme winter weather and travel disruptions in mid-March.

A polar vortex collapse occurs when sudden stratospheric warming weakens the polar vortex, allowing Arctic air to move southward.
The upcoming event, expected in mid-March, could bring freezing temperatures and winter storms to parts of the US, Canada, the UK, and Europe.
This marks the second polar vortex disruption of 2025, following a February collapse that caused widespread cold and travel chaos in North America.
Meteorologists note that changes in the jet stream could lead to unpredictable weather patterns, with colder conditions lasting into late March or early April.
Experts suggest that human-caused climate change may influence the frequency and intensity of such events, though the exact role remains complex and debated.
