Arctic cold outbreak over Europe
-
A Sudden Stratospheric Warming (SSW) observed last week over North Pole.
The temperature rose from -80 to -37 C.
Following this warming, the high altitude winds reverse to flow eastward
instead of their usual westward and weaken the jet stream.
This results in easterly winds near the surface and a dramatic reduction
in temperature (eastern, central, western Europe and parts of Mediterranean and Balkans) by the end of the weekend and is expected to last into March.We'll monitor the situation
