The meridional structures of tropical sea surface temperature (SST) play an important role in impacting the variations of Hadley circulation (HC), and the response amplitudes of the HC to different meridional tropical SST structures show contrasting differences. Using the simulations of phase 5 of the Coupled Model Intercomparison Project (CMIP5), the performance of the state-of-art models in reproducing the response contrast of the HC to different SST meridional structures during the seasonal cycle is evaluated in this study. The result indicates that the models show high skills in capturing the climatological features of annual mean HC and tropical SST. Moreover, the leading variabilities of HC and tropical SST during the seasonal cycle are well reproduced for both the equatorially asymmetric and symmetric variations. Furthermore, most of the models display good agreement with the observations in depicting the responses contrast of the HC to different SST meridional structures. These results indicate that the current CMIP5 models show high capability in capturing the response of HC to tropical SST during the seasonal cycle, and provide confidence for further detecting the future variations of HC.
