Through the simulation of climate seasonal change in China, the performance of a regional climate model with p-· incorporated coordinate is tested.The results show that the model can relatively well reproduce the seasonal changes of pressure systems,as well as the seasonal march and withdraw of rainbelt in the east of China.The simulated seasonal characteristics of precipitation in climatic subregions are also basically similar to the observations with discrepancies that the precipitation is underestimated over east and south China in spring and is overestimated over east,southwest and northwest China in autumn. Overall,this model has certain capacity to simulate regional climate in China and can be used as a regional climate model.
