通用地球系统模式对亚洲夏季风降水的模拟能力评估
Evaluation of community earth system model in simulating Asian summer monsoon precipitation
摘要
Abstract
The performance of the Community Earth System Model(CESM,vesion1.0.3) in simulating the Asian summer monsoon precipitation was assessed by comparing with the observational/reanalysis datasets and the models outputs participating in the fifth phase of the Coupled Model Intercomparison Project (CMIP5).Results show that the CESM can simulate the climatology of Asian summer monsoon precipitation reasonably,but it simulated less precipitation in Southeast China and more one in western plateau region of China,which is similar to the results of other CMIP5 models.CESM can reproduce the seasonal variation of wet summer and dry winter,northward or southward migration of the rain belt,whose simulation biases are different regionally and seasonally.The EOF analysis results show that the CESM also has the ability to simulate the spatial-temporal variations of the summer monsoon precipitation and show better performance on revealing the relationship between the Asian summer monsoon precipitation and El Ni(n)o-Southern Oscillation (ENSO) than other CMIP5 models.Generally,the CESM is reliable to simulate Asian summer monsoon precipitation and is comparable to the four best models selected from those participate in CMIP5.关键词
