摘　　要：介绍大气模式中湿过程的饱和凝结、对流参数化和显式云物理三种方法的适用条件和特点。中尺度大气模式的对流参数化和显式过程一般有多种方案 ,介绍了多种方案的主要处理方法、基本微物理过程、预报量和主要特点。对流云模式都采用显式过程 ,但不同模式的湿过程有一定的差别 ,有各自的微物理特点 ,对有代表性的云物理方案进行了叙述和分析。Stable precipitation, convective parameterization, explicit schemes are three methods for an atmospheric model of describing the cloud and precipitation processes. Most mesoscale models have several schemes to select, and different choices are different in some microphysical processes, features and variables. Cloud models have relatively complicated and developed schemes, among which also there exist many differences. A general introduction of convective parameterization, explicit schemes of mesoscale models and cloud models are overviewed and simply analyzed.
