摘　　要：本文利用有限区域数值预报模式MM4对一次华南暴雨过程进行了数值模拟和试验。用该模式预报的形势场与实况较一致，预报的暴雨强度、位置也与实况相近。此外由控制试验和敏感性试验可知，该暴雨强度对地形、辐射和下垫面过程比较敏感。The numerical simulation and experiments of a storm rainfall in South China are investigated by limited-area model MM4. The weather system and precipitation predicted by the model is close to the real case. The results of control experiment and sensitivity experirrents also show that the precipitation is highly sensitive to the physical processes,for example topography,effect of cloud in radiation heating,the exchanges of heat and vapor between ground(or sea surface)and atmosphere.
