Abstract Based on the monthly precipitation data of APHRO_MA_V1101 observed from 1961 to 2005 and the monthly average precipitation data of 33 global climate models simulated by CMIP5,the ability of the model to simulate historical climate and its change is tested.The results show that there is a clear northward promote characteristics on China's eastern rain belt from early summer to midsummer.The inmcm4 and CNRM-CM5 models are best for the simulation of the climatic state of the rain band northward promote in eastern China.The precipitation anomalies in eastern China are used as a measure of the unusual rain band northward promote from early summer to midsummer.The precipitation climate trends in July for eastern China increase in the south of the Yellow River and decrease in the north of the Yellow River.The HadGEM2-CC and CanESM2 models are best for the simulation.
