中文摘要: 对上海2001年8月5~6日特大暴雨的天气形势做了详细分析指出,在副高内由东风系统发展起来的热带低压由于结构深厚得以在强大副高内稳定维持,而副热带高压断裂的形势变化至关重要,由于西环副高北侧的西北偏西气流渗入,对热带低压内强对流迅速、持久发展起了重要作用,同时东环副高减退,又成为热带低压路径突然东折的主要因素。
Abstract:After detailed analysis of the weather pattern of torrential rainstorm in Shanghai on August the 5th 2001,it is pointed out that the main reason of ″0185″ tropical depression can maintain steadily in the strong subtropical high is its deep structure.And the break of subtropical high is the key inducement of pattern′s following evolvement.The western high′s north northwest stream at its north side flows into the tropical depression,which makes the strong convection among the tropical depression developing rapidly and continuously.Furthermore,the eastern high′s weakening is the main inducement of the ″0185″ tropical depression′s sudden eastward movement.
