Stratospheric Circulation in the Southern Hemisphere: Links to Tropical Winds, Ozone, and the Hunga Eruption—Part 1: Evidence From ERA5 Reanalysis
The interannual variability of the Southern Hemisphere polar vortex plays a key role in ozone depletion and recovery but this variability and its teleconnection patterns are less understood than in the Northern Hemisphere. Using ERA5 reanalysis data from 1980 to 2022 (43 years), we studied the variability of the Southe...
