Polar vortex weakening months earlier than usual: meteorologists record an unprecedented November disruption
Meteorologists are observing an unusually early weakening of the polar vortex over the Arctic — signs of disruption have been recorded as early as November, whereas such events usually occur from January to March. According to Professor Andrew Charlton-Perez of the University of Reading, scientists have never before observed such an early sudden stratospheric warming. This raises the probability of cold spells in northern and central Europe in the coming weeks, but the final effect depends on the position of high-pressure areas.
