海河流域"25·7"区域性大洪水降雨背景分析及启示
Analysis of the rainfall background and implications of the"25·7"regional major flood in the Haihe River Basin
摘要
Abstract
From July 24 to 29,2025,due to continuous heavy rainfall,many rivers such as Chaobai River,Luanhe River and Daqinghe River experienced heavy rains and floods,which triggered the"25·7"regional major flood of the Haihe River Basin.The intense rainfall process was characterized by its high extremity,large cumulative precipitation,extensive impact area,concentrated heavy rainfall zone,and long duration,being particularly notable for the extremity of daily rainfall amounts and the vast area affected.Causality analysis indicates that the abnormally stable Western Pacific Subtropical High and its interaction with northward-moving typhoons,which created abundant water vapor transport,served as the key circulation background.This event occurred within the climatic context of the northward expansion of the summer rain belt in China,revealing a new characteristic of increased frequency and intensity of extreme precipitation in North China.In the face of escalating risks of frequent and severe extreme weather events in the future,it is recommended to systematically enhance the comprehensive flood disaster prevention and response capabilities of the Haihe River Basin by strengthening watershed monitoring,improving inter-departmental emergency coordination,applying risk census results,reviewing flood control standards,and raising public awareness of disaster prevention.关键词
