Abstract

Heavy rainfall is a serious hazard, which lead to losses of urban property and cause casualties. In this paper, based on hourly precipitation data of Guanxiangtai meteorological station of Beijing, bivariate joint distribution of heavy rainfall is established using the observed data of accumulated precipitation and duration. The joint return periods of heavy rainfall are calculated. The results show there is a significant linear relationship between factors of accumulated precipitation and duration. GEV distribution is appropriate for accumulated precipitation and duration, and the joint distribution of the two variables can be characterized by Gumbel Copula, which is more comprehensive in analyzing the frequency characteristics of heavy rainfall events. The research can provide a foundation for further applications in disaster prevention and reduction.
