摘　　要：１９９６年安徽省的梅雨总量与１９９１年相近，但洪涝灾害造成的经济损失仅是１９９１年的１／２。分析认为：１９９６年梅雨期的非稳定性暴雨（暴雨落区多变）是主要因素，梅雨期集中，暴雨落区偏南，梅雨前期雨水偏少也是重要原因。并对１９９１年和１９９６年梅雨期稳定性暴雨（暴雨落区少动）和非稳定性暴雨的环流特征、影响系统进行了分析对比。The total Mei yu precipitation in Anhui province in 1996 is nearly identical with that in 1991.But the economic losses caused by flood and waterlogging is only half of 1991′s.The unstable torrential rain with characteristic of variable falling area during 1996 Mei yu season is the principal factor,and the concentrated torrential rain regions towards to the south and the less precipitatin on in earlier stage of Mei yu season are aslo important factors.By the contrast analysis on the circulation characteristics and the impact system between the stable torrential rain and the unstable torrential rain,the preliminary research way that can be used to estimate the damage situation in large Mei yu precipitation year is given.
