新暴雨形势下上海市设计暴雨雨型研究

Study of Shanghai Design Rainstorm Profile Under the New Rainstorm Situation

雨型是描述降雨过程的概念,是降雨强度在时间尺度上的分配过程,是获取雨水径流过程线的基础.设计暴雨雨型是当地在大量暴雨资料统计规律基础上选定的最有代表性的雨型.本研究利用上海市多年（1985~2012）降雨资料,建立了具有典型性、代表性的上海市设计暴雨雨型.

Rainfall pattern is a conception that describes rainfall process, and it is a rainfall intensity allocation process under time scales, and it is the basis on obtaining storm water runoff hydrograph. Design rainstorm profile is the most typical Rainfall pattern that was from the statistical regularities on the basis of large amount of local rainfall data. In this study, on the basis of many years（1985~2012） rainfall data of Shanghai, the recommended, typical and representative Shanghai Design Rainstorm Profile was presented.
