摘要: This study investigates the changes in atmosphere-ocean interactions over South China Sea (SCS) by analyzing their variables period of 1979~2011 during boreal summer (June-July-August). It is found that a simultaneous correlation coefficient between sea surface temperature (SST) and precipitation SCS significantly changed before after late-1990s. That is, variation negatively (positively) correlated with SST variations (after) Our further analysis indicates atmospheric forcing dominant late-1990s accompanying wind-evaporation feedback cloud-radiation feedback. After late-1990s, contrast, atmosphere through latent heat flux from ocean to dominant. change relationship are associated Northeast Asian precipitation. In particular, Asia becomes stronger than We argue increase may lead direct
