Meteorologists detect unprecedented early polar vortex disruption

–

Neutral summary

On Friday, November 6, meteorologists observed an unprecedented early weakening of the polar vortex — a vast system of cold air and low pressure that normally circulates from west to east at high altitudes above the Arctic. The phenomenon increases the risk of cold waves across the Northern Hemisphere, though its consequences remain uncertain. Cold air could push southward, affecting Europe, North America and Asia. The vortex typically peaks around January and has not yet reached that point. The UK Met Office warned that the weakening could lead to the earliest recorded sudden stratospheric warming event, potentially bringing colder weather and snow to Britain. Some outlets suggest a possible link to El Niño, but no consensus has been reached on the cause. Forecasters will continue to monitor the vortex in the coming weeks.
