| 摘 要： | Based on height and wind data of NCEP/NCAR and OLR data,patterns of upper aircirculation from April to October have been analyzed,and the South China Sea (SCS) SummerMonsoon Onset (SMO) and retreat have been defined.The empirical formula fitting to the onsetindex of the SCS SMO has been established,and the onset and ending time of monsoon,togetherwith the intensity index sequence during 1953—1999 are given by the analysis of characteristics ofthermodynamic and dynamic factors during the process of SMO.The emergence and developmentof symmetric vortex pair at both sides of the equator in tropical East Indian Ocean,which mayexcite the SCS SMO,can be taken as a short-term prediction indicator of SMO.
