Is the polar vortex coming? Looking ahead, much colder air is predicted to arrive in waves across the central, eastern and southern U.S. over the first week to 10 days of January.
During the 2014 January polar vortex, more than 20 people across the country died from the cold as places like Georgia — which rarely see serious cold — dealt with lows under 10 degrees ...
The polar vortex is also thought to have had effects in Europe. For example, the 2013–14 United Kingdom winter floods were blamed on the polar vortex bringing severe cold in the United States and Canada. [8] Similarly, the severe cold in the United Kingdom in the winters of 2009–10 and 2010–11 were also blamed on the polar vortex. [9]
Obviously this isn’t the first polar vortex episode of the winter, but it looks to be the most severe.” A stretched polar vortex like this one happens lower in the atmosphere and is different than when the polar vortex has sudden warming, weakens and all the cold air escapes south and out of the poles, Cohen said.
[4] [5] In the SH, SSW accompanied by a reversal of the vortex westerly (which is soon after followed by a vortex recovery) was observed once during the period 1979–2024; this was in September 2002. [6] Stratospheric warming in September 2019 was comparable to or even greater than that of 2002, but the wind reversal did not occur. [7] [8] [9]
At least 10 of these stretched polar vortex events have occurred this winter, including the ongoing event, according to Cohen: four in December, four in January and two in February.
