长江中下游致洪暴雨过程及强度

基于地面气象台站的降水量资料，根据“降水极端强度-持续时间”理论定义降水相当强度，综合体现前期累计雨量、降水持续时间、日最大雨量在致洪暴雨形成中的叠加作用，突出对洪涝有直接显著影响的降水。1961-2020年长江中下游致洪暴雨过程及强度数据集包括以下信息：致洪暴雨开始日期、结束日期、持续天数、强度、致洪暴雨等级、单站日最大雨量、过程累计面雨量等。

Based on precipitation data from ground meteorological stations, the equivalent precipitation intensity is defined according to the "Precipitation Extreme Intensity-Duration" theory, which comprehensively reflects the superimposed effects of antecedent accumulated rainfall, precipitation duration and daily maximum rainfall on the formation of flood-causing rainstorms, and highlights precipitation that has a direct and significant impact on flood disasters. The dataset of flood-causing rainstorm processes and their intensities in the middle and lower reaches of the Yangtze River from 1961 to 2020 includes the following information: start date, end date, duration days, intensity, flood-causing rainstorm grade, daily maximum rainfall per single station, areal accumulated rainfall during the entire rainstorm event, etc.
