Polar Vortex 2024 March. As a result, the march 2024 total column ozone levels in the northern hemisphere stratosphere were the highest since 1979. Following a polar vortex disruption in early march, winds at 60 degrees north (outlined in magenta) on march 16, 2024, were mostly from the east—a reversal of the normal wintertime circulation of the polar stratosphere.
It’s in the top six strongest reversals since 1979, climate. You can see a rapid wind speed reduction of the polar vortex in early march.
