Short summary
We use a global atmospheric chemistry and climate model to study the efficiency and effectiveness of the deep convective transport of CO, NH3 and SO2 from the planetary boundary layer into the Asian summer monsoon anticyclone. We find that in contrast to CO and NH3, the SO2 enhancements within the anticyclone are very weak. The wet scavenging over South Asia is more effective for SO2 than NH3 at reducing their amounts reaching the Tibetan Plateau and the Asian summer monsoon anticyclone.
