Using the synthetic analysis method, this paper analyzes the differences and their corresponding mechanisms of summer precipitation in East Asia in EP and CP years, respectively. The results show that different types of El Nino do play a significant role in precipitation by regulating the different atmospheric circulations. The large amount of precipitation in EP year is more northward than CP years. Correspondingly, there is a cyclone in Northeast Asia in EP years with subtropical high anomalies southward, making the convergence of moisture with the southerly wind anomalies. With good vertical movement conditions, these atmospheric circulations provide a good atmospheric circulation background for the precipitation.
