TWO-DIMENSIONAL, TIME-DEPENDENT CLOUD CHEMICAL MODEL
二维时变的积云化学模式

A chemical cumulus model was developed to study the evolutions of cloud and rain, pH value and sulfate concentrations of cloud and rain, as well as the scavenging of SO2, NH3, dust, O3 and H2O2, coupled with a two-dimensional,time dependent cloud model. With the growth of the cloud, the acidities of the cloud water and the rain water increase Ammonia greatly affects the pH values of the cloud and the rain water. Scavenging of SO2, NH3, dust, O3 and H2O2 by cloud and rain is evident.
