摘　　要：文章基于“2023.7.30”暴雨观测数据,分析海河流域极端暴雨特性。本次暴雨是在反向偏移的太平洋高压以及副热带高压持续增强的双重影响下发生的,主要集中在2023年7月29日—30日,降水历时平均值在46 h左右,广泛分布在大清河、子牙河和漳卫河部分水系,暴雨中心共有4个,其中最大1 h降雨量的重现期均值为6.5年、最大6 h降雨量的重现期均值为37年、最大24 h降雨量的重现期均值为326年、最大3 d降雨量的重现期均值为336年。Based on the observational data of the“2023.7.30”extreme precipitation event,this paper analyzes the characteristics of extreme rainfall in Haihe River Basin.It occurred under the synergistic interaction between the Pacific high and the subtropical high,and exhibited total precipitation duration of 46 hours(July 29-30,2023).This event primarily affected Daqing,Ziya and Zhangwei River system with four precipitation cores.Date analysis revealed respective average return periods:the maximum 60-minute rainfall was 6.5-year recurrence interval,the maximum 6-hour rainfall was 37-year recurrence interval,the maximum 24-hour rainfall was 326-year recurrence interval,and the maximum 72-hour(3-day)rainfall is 336-year recurrence interval.
