In this study, the features of intra-seasonal(10-30 d) precipitation variability over southern China during the autumn, winter and following spring season of different types of ENSO events are analyzed based on the Hadley Centre sea surface temperature(SST), National Centers for Environmental Prediction(NCEP) and National Center for Atmospheric Research(NCAR) atmospheric circulation data, and China daily rainfall station data. The results show that the impacts of different ENSO types on the intra-seasonal(10-30 d) precipitation variability over southern China vary with the different seasons. During the winter and following spring of EP El Niño events, the 10-30 d precipitation variability over southern China is significantly enhanced. Intra-seasonal precipitation variance is weakened during the CP El Niño autumn, yet strengthened during the CP El Niño winter, thus showing inverse features. The impacts of La Niña events on the 10-30 d precipitation variabilities are relatively minor and unstable. Further analyses show that the impact on the 10-30 d precipitation variability is closely related to the responses of seasonal atmospheric circulation anomalies over the western North Pacific associated with ENSO events. Compared with normal years, a strong anticyclonic circulation anomaly occurs over the Philippines during the EP El Niño years. The anomalous southerly winds on the western side of the anticyclone transport much greater amounts of water vapor northward to southern China, which favors the strengthened 10-30 d rainfall variability. However, an anomalous cyclonic circulation occurs in the western North Pacific during the CP El Niño autumn, which suppresses the tropical water vapor transporting northward to the East Asian continent. During CP El Niño winters, an anomalous anticyclone appears over the western North Pacific, and though its intensity is weak, it accounts for the inverse low frequency rainfall responses in autumn and winter. When La Niña occurs, the anomalous cyclonic circulation over the Philippines is weak, which results in the relatively weaker responses of the 10-30 d precipitation variability over southern China.
