ased on citations of important impacts of the atmospheric Intraseasonal Oscillation (ISO) on heavy rainfall, the main characteristics and mechanisms of atmospheric ISO associated with the continuous heavy rainfall over the Yangtze River Valley (YRV) in China are reviewed in summary. Research on the spatial and interannual variations of the global atmospheric ISO patterns and their relationships to the continuous heavy rainfall over YRV are emphatically discussed and comments are given. We try to completely summarize the understanding of the climate characteristics of the rain ISO over YRV and the influences of the different tropical and extratropical ISO patterns on persistent heavy rains over East Asia subtropical region. Moreover, combined with the research level of the connections between ISO of both hemispheres and continuous heavy rainfall over YRV, some valuable scientific issue and potential research topics in future studies for the interactions between the different time scales ISO and persistent heavy rains and the extendedrange forecast of the strong precipitation over YRV are also discussed in order to emphasize the roles of the ISO in Southern Hemisphere on the climate system of the global and East Asia subtropical region. These studies might therefore provide valuable information for the extendedrange forecast of the heavy precipitation process during the 10~30 days and climate predictions of drought and flood over YRV.
