摘　　要：文章利用格点资料及其它常规资料，分析了越赤道气流与我国洪涝灾害间的关系，指出越赤道气流较强的年份，我国夏半年降水亦偏强偏广．在我国发生洪涝灾害的年份，越赤道气流通道的位置发生重大偏移，同时有“强信号”提前出现，因此有可能对洪涝灾害进行中长期预测．he relationship between flood disasters over China and the crossequatorial flow (CEF) is studied by using the grid wind data and other routine observations. The results show that the rainfall of summer half year over China was on the strong and broad side in the year of strong CEF. The positions of CEF paths would move greatly during the flood years in China, and in the meanwhile a “strong signal” would appear in advance, therefore, the extended and longrange forecast of flood disasters could be made.
