摘　　要：In this paper, a 1-D time dependent cold cumulus chemistry model is presented. In the cold cumulus model, 4 categories of hydrometeors: cloud drops, raindrops, cloud ice crystals, graupel particles, and 18 microphysical interactions are considered, In the chemical model, the source and sink terms for pollutants include: the complicated interactions between pollutants (gases and aerosol particles) and the hydrometeors (especially ice crystals and graupel particles), the ex- changes of chemical compounds between two hydrometeors accompanying microphysical processes and the aqueous oxidations of S (IV) to S (VI). The two models are combined to study the acidifi- cation processes in cold cumulus clouds.In this paper, a 1-D time dependent cold cumulus chemistry model is presented.
