| 摘 要： | By use of the May—September 1980—1986 ECMWF daily data of u,v,r and T at 850 hPa,a comparative analysisis performed of basic features of moisture transportation at seasonal mean,quasi-40-day,-biweekly,and-weeklyoscillations,indicating that the seasonal mean transfer plays a decisive role in the moisture flux over the Asian monsoonregion,displaying the integer of the monsoon systems there in character;that the transport related to these tropicalintraseasonal oscillations are of equal importance in the monsoon period except the difference in their behaviors,i.e.,thetransfer shows considerable relative independence in the South-and East-Asian systems;and that the transport at allthese intraseasonal oscillations is found to be feeble at equatorial latitudes with little or no influence on each other forboth hemispheres.
