Abstract: The complex terrain and surface conditions in Southeastern China and Taiwan Strait bring large uncertainties of cumulus convection activity, making it difficult to simulate and predict the precipitation in this region. In order to discuss the applicability of Regional Climate Model on simulating precipitation in Southeastern China, this paper selects 4 different cumulus parameterization schemes (i.e., Anthes-Kuo, Arakawa-Schubert, Fritsch-Chappell and MIT-Emanuel) to simulate the precipitation and compares for the test with highresolution（0.25°×0.25°）monthly mean TRMM (Tropical Rainfall Measuring Mission). The four schemes can roughly reproduce the spatial structure and seasonal variation of precipitation. Specially, the Fritsch-Chappell scheme and MIT-Emanuel scheme can both well reproduce the spatial distribution of precipitation, especially the simulated extremes of precipitation in the southern part of Taiwan Island and the coast of Guangdong. Further, MIT-Emanuel scheme has the best simulation for the seasonal and interannual variations of precipitation. The equivalent potential temperature at different height levels shows that the simulated convection activity by the MITEmanuel scheme is strong, which makes the simulated precipitation amount closer to the observed results. Therefore, it is reasonable to choose the MIT-Emanuel scheme to simulate the regional climate in Southeastern China and Taiwan Strait.
