A wave of cold polar air could hit Europe in early December
Comments
A fresh wave of cold polar air is set to hit Europe in early December, according to projections from the latest meteorological models.
It is caused by a sudden stratospheric warming that pushes cold air from the North Pole further south towards Europe — and could even reach parts of North Africa.
This sudden warming of the stratosphere around Siberia could also potentially destabilise the so-called polar vortex, a phenomenon that keeps cold air close to the Arctic Circle.
According to the above forecasts, the episode would be relatively fast-paced and would be followed by higher than normal temperatures for the wintry season in Europe.
In the meantime, another storm travelling in from the Atlantic can be expected this weekend.
Nicknamed Cecilia, the storm is expected to bring heavy rain, strong winds and waves to the Cantabrian and the Mediterranean in France and Spain.
