摘　　要：分析 2 0 0 1年云南雨季开始期东南亚环流形势的逐日演变 ,并用OLR资料分析了雨季开始前东南亚对流活动的逐日演变。指出云南雨季开始受孟加拉湾季风影响 ,孟加拉湾季风爆发早且偏强 ,导致云南 2 0 0 1年雨季开始偏早 ,雨量偏多 ,在预报云南雨季开始时东南亚地区环流的季节调整及对流活动的北上应是重要因素。The circulation evolution and the convective activity of the southeast Asia region before the rainy season for Yunnan in 2001 is analyzed. The rainy season beginning of Yunnan is influenced by the summer monsoon of the BOB, the Bay of Bengal monsoon onset is earlier and stronger so that the rainy season is earlier and the rainfall is more in 2001. The seasonal adjustment and the convective activity migration to north of the southeast Asia region is an important factor to forecast the rainy season beginning of Yunnan.
