本文提出了一个基于水文气象特征的降水事件分类系统。目的是表征不同的事件类和它们的应用程序在建模强度持续时间频率曲线和设计雨型。定义了一个与降水的对流性强弱有关的参数β*，并研究了它在整个样品系列中的分布。此外，还分析了所获得的不同类别的主要特征及其与洪水和降雨灾害事件的关系。Jardí雨量计（西班牙巴塞罗那）1927年至1981年的强度系列被用作样本系列。版权所有© 2001皇家气象学会
A system of rainfall events classification on the basis of their hydrometeorological characteristics is proposed. The objective is the characterization of the different event classes and their application in modelling intensity–duration–frequency curves and design hyetographs. A parameter related to the greater or lesser convective character of the precipitation, designated as β*, is defined, while its distribution throughout the entire series of the sample is studied. In addition, the main features of the different classes obtained and their relationship to floods and rainfall damage events have been analysed. The intensity series of the Jardí pluviograph (Barcelona, Spain) between 1927 and 1981 is used as a sample series. Copyright © 2001 Royal Meteorological Society
