| 摘 要： | 通过对区域气候季节变化的模拟,对p-·坐标系区域气候模式的模拟能力进行了检验。模式较准确地再现了中国区域气候系统的季节性变化特征及中国东部降水带的季节性进退,模拟的各气候区降水的季节变化趋势也与实况基本相符,但模式低估了华东和华南地区的春季降水,而高估了华东、西南和西北地区的秋季降水。

| Abstract: | 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. |
