The possible impacts of the tropical western Pacific SSTA on China’s precipitation during the El Ni〖AKn~D〗o developing phases are emphasized in this paper. Analyses of all the 17 summers during the El Ni〖AKn~D〗o developing phases show that precipitation in these summers varies from year to year and does not exhibit a significant relationship with the El Ni〖AKn~D〗o indices (Ni〖AKn~D〗o3 and Ni〖AKn~D〗o3.4 index). However, further analyses reveal that the precipitation is closely related to the tropical western Pacific SSTA during these summers. When the tropical western Pacific is warmer, it is wetter in the south of the Yangtze River and drier in the north, and vice versa. The possible mechanism is also proposed. The different conditions of the western Pacific SST anomalies indicate different distribution features of the SSTA in the tropic Oceans. The different tropical SST patterns can induce different responses to the tropical and the subtropical atmospheric circulation near East Asia. Therefore, the precipitation in the east of China is affected. Besides, the anomalous warm SST in the western Pacific may contribute to the precipitation anomaly in the summer of 2014. The tropical western Pacific in the summer of 2014 is warmer than all the previous 17 summers during the El Ni〖AKn~D〗o developing phases. Such a condition of the tropical western Pacific favors more precipitation in the south of the Yangtze River and less in the north. And the observation of precipitation is also characterized by such a feature. Thus, the tropical western Pacific SSTA may exert an impact on the summer precipitation in 2014.
