| 摘 要： | 强对流天气过程受大尺度天气系统的制约,而与中尺度天气系统的联系更为直接,因此近20多年来,中尺度天气系统越来越引起人们的关注。早在1963年,我国进行了华东地区中尺度分析试验研究,1976年后又相继在华南、湘中和长江下游地区组织了中尺度系统的观测试验研究,对中尺度系统的活动规律以及与天气的关系得到了不少有意义的成果。作者也曾发现浙江大范围强对流天气与中

| Abstract: | The use of the band-pass filter is made to analyze the rnesoscale systems in large-area:severe convection events over Zhejiang.It is found that all cases analyzed are closely related to the mesoscale surface depressions.The outbreak of severe convection in the depression is derectly related to the moisture convergence and the asending motion in the boundary layer.Most of hailfalls occur in the convergence center. |
