Short summary
The the role of deep convection in stratosphere–troposphere dynamical coupling in the tropics was studied during two large major stratospheric sudden warming events in January 2009 and January 2010. Convective activity and precipitation increased in the equatorial Southern Hemisphere as a result of a strengthening of the Brewer–Dobson circulation induced by enhanced stratospheric planetary wave activity.
