: Cloud microphysical scheme plays a significant role in cloud and precipitation simulation, and it is however one of the main error originations in predictions. An overview of the progresses in the cloud microphysical parameterization in mesoscale models has been done, and a statistical analysis of the sensitivity experiment results on the microphysical parameterization schemes over China have been performed. The Lin and RutledgeHobbs schemes lay a solid foundation for the development of cloud microphysical parameterization, and all later developed schemes were directly or indirectly based on the Lin and RutledgeHobbs schemes with some improvements. These improvements mainly include:①number of hydrometeor classicication; ②ice nucleation; ③hydrometeor particle size distributions; ④given values of intercept for the hydrometeor particle size distributions, and ⑤the threshold values for autoconversion processes. According to the statistical results, the Lin scheme in the Weather Research and Forecasting (WRF) model performed well in simulations, and the Goddard and Reisner schemes in the PSU/NCAR Mesoscale Model (MM5) simulated well.
