Short summary
The sudden stratospheric warming (SSW) event that occurred in September 2019 in the Southern Hemisphere was analyzed. A large warming and decelerated westerly winds were observed in the southern polar region. Since a reversal from westerly to easterly winds did not take place SSW2019 was classified as a minor SSW. The total wave forcing and the contribution from PW1 were larger in 2019. The strong and long-lasting planetary-scale waves with zonal wavenumber 1 played a role in SSW2019.
