摘　　要：本文分析了云南５月份降水与前期１—３月北半球１００，５００ｈＰａ高度场的关系，研究了影响云南５月份旱涝的大气环流系统及主要大气活动中心，探讨了遥相关场的波列结构。The relationships between precipitation in May in Yunnan province and 100 hPa,500 hPa geopotential height fields of the Northern Hemisphere from January to March are studied by using monthly mean data during 1956 1992. The effect of atmospheric circulation systems and the variation of main atmospheric active centres on drought/flood in May in Yunnan province,and wave train construction of teleconnection are studied. Based on the analysis of the circulation variation,a long-range forecast method is formed.
