Where is the Polar Vortex going to hit?
A new stratospheric Polar Vortex has now emerged over the North Pole and will continue to strengthen well into the Winter of 2021/2022. It will interact with a strong easterly wind anomaly high over the tropics.
Is another Polar Vortex coming 2022?
A warming event begins for the Polar Vortex in the stratosphere, powered by the strong cross-polar ridging, as we head into the 2022 Spring season. The Polar Vortex is facing a stratospheric warming event, which will be strong enough to cause a temporary split of its outer core.
Is a Polar Vortex coming in 2021?
The Polar Vortex has just returned for the cold season 2021/2022, yet it is already facing its first stratospheric warming event. An unusually early warming event is starting over the Polar regions, with more warming forecast to follow into the late month.

Is the Polar Vortex weakening 2022?
The black line is the long-term average, and the blue line is the polar vortex strength in the 2021/22 season. But the red line is actually the forecast, which shows the rapid weakening of the polar vortex is now starting and will continue into the month of March.

How strong will the polar vortex be in September?
Current forecasts, when compared to the long-term average, show that the late September strength of the polar vortex is likely to be higher than usual. That is seen in the image below which shows the forecast of the stratospheric jet stream at 10mb (~30km), compared to the long-term average (yellow line).
What happened to the polar vortex in December?
In early December, the polar vortex was at a strong level, reaching over 40m/s (90mph) zonal wind speeds. Towards mid-month, and especially towards late December, the polar vortex began to weaken. We can see the stratospheric zonal winds became negative in early January, due to the warming event that collapsed the polar vortex.
How many Americans have been affected by the’polar vortex’?
Some 250 million Americans overall have experienced the “polar vortex” conditions. Read more here. And in the UK, travel by road, rail and air has been disrupted by snow and ice, with weather warnings issued for Friday and overnight.
What is a polar vortex and what causes it?
Technically, the polar vortex refers to the winds that orbit the Arctic and keep the cold “locked” far to the north. But with a peak temperature, known as sudden stratospheric warming, cold air can break through the “ring” and head south.
