CMIP5模式中El Ni(n)o-EAWM关系的模拟对东亚冬季风模拟的影响
Impact of simulation of El Ni(n)o-EAWM by CMIP5 models on the East Asian winter monsoon
摘要
Abstract
By using the statistical methods,the simulation of 17 coupled models derived from the Fifth Coupled Model Intercomparison Project (CMIPS) on interannual variability of the East Asian Winter Monsoon (EAWM) was evaluated.Results show that most models have a certain simulation effects on the interannual variability of the EAWM,especially for the 500 hPa East Asian trough.The interannual variability of the main systems of EAWM is simulated better in space than in intensity,and the simulation on intensity is slightly weaker than the observations.The comprehensive evaluation proved the best simulation ability of bcc-csm1-1,CCSM4,HadCM3 and NorESM1-M.According to the large deviation of the interannual simulation ability among models,four best models and five worst models are selected to discuss.The results show that the simulation ability of models on relationship between El Ni(n)o and EAWM (El Ni(n)o-EAWM) is key factor for the bias in the case of evaluating the influence of El Ni(n)o on the circulation in East Asia winter.In other words,good interannual simulation ability on EAWM interannual variability are attributed to the reasonable simulation of El Ni(n)o-EAWM.关键词
