摘要
本文利用云内成雨清除模式和云下雨水冲刷清除模式讨论了云内和云下致酸物质的清除、酸化过程。计算结果表明：雨水酸化主要是在云内形成、而云底之下雨水对清除酸化过程是不重要的。而对流引起的上升气流和下沉气流对污染层内致酸物质的浓度变化有较大影响。
The removal processes of acid species and acid processes are described using numericalmodel including both the washout and the rainout. It has been shown that the acidification ofrain water mainly occurs in in -cloud and that the below-cloud scavenging of the acid speciesby falling rain has little influence on the acidification. It has been also shown that the verticalvelocities of the air have large influence on the concentrations of the acid species in the tropo-sphere with the acid species.
