英文摘要	The acidification of precipitation and the wet removal of pollutants in South China in spring are evaluated by using a one dimensional, time-dependent, physico-chemical model of stratiform clouds. The results are consistent with the mean field data. In the typical condition, the in-cloud scavenging of gases and aerosols is the major removal process at the beginning of rainfall, then fractions of below-cloud scavenging of S(VI) from S(IV) oxidation, NH3, HNO3 and particles increase gradually. It can be treated as an irreversible process, Numerical tests show that the concentration of oxidants, H2O2 can affect wet removal of SO2, as well as the formation and deposition amount of S(VI). The convergence of airflow can compensate partially the depletion of pollutants by wet removal.; Environmental Sciences; Meteorology & Atmospheric Sciences; SCI(E); 0
