To explore the relationship between EI Nino event and the summer precipitation, the variation trend and mutation of Nino index are firstly examined to identify the types and intensity characteristics of El Nino events during 1961-2016. The spatial distribution and inter-annual variation pattern of precipitation are then examined by analyzing the monthly precipitation anomaly using EOF method. Emphasis is placed on the analysis of the characteristics of El Nino events during 2014-2016, and their impacts on the temporal-spatial distribution of the summer precipitation in 2016. The study shows that both Nino index and the precipitation variability fluctuate significantly during the period of EI Nino event, and the spatial and temporal distribution of precipitation in the next summer is largely influenced by the event. Specifically, the summer precipitation appears to increase in Yangtze River basin and decrease across most northern Huai River Basin and the southeast coastal areas after Eastern EI Nino’s heyday. For Central EI Nino, the summer precipitation appears to decrease in Yangtze River Basin and increase in Yellow River Basin and Southern China. For Mixed EI Nino, the increase in summer precipitation is detected across the Yellow River Basin.
