What Is A Polar Vortex 2024 In India. The stratospheric polar vortex is a huge spinning wheel of freezing cold air that forms high up in the atmosphere near the north pole, according to nasa. When the polar vortex is weak, with higher temperatures and slower winds than usual in the stratosphere, the ozone depletion process is weaker, leading to ozone columns above 220 dobson units (du), the threshold value used to define the antarctic ozone hole.
(nasa/goddard space flight center scientific visualization studio) a major current of circulating air called the arctic polar vortex has completely reversed course and is now spinning ‘backwards’. Based on the january 15, 2024 forecast, the stratospheric polar vortex winds will decrease to zero, just reaching the threshold of a major sudden stratospheric warming, in the next day or two.
