In addition to greater precipitation on extreme days of precipitation, preceding and succeeding (PSP) is often an objective component flooding in the mid–lower reaches Yangtze River Basin (MLRYRB). this study, focused temporal distribution pattern concept event (EPE), defined as a consecutive having at least one daily extreme, proposed consider PSP event. We analyzed spatiotemporal variation four types EPEs based data obtained from 130 monitoring stations covering 1960–2019. Extreme increased significantly over last 60 years (p < 0.01). The frequency amount single-day accounted for only 13% 21%, respectively, while multi-day continuous EPE that are associated with 87% 79%, confirming connotations EPEs. front late under 100-year return level reached 250 mm 230 mm, respectively. Furthermore, climate warming could lead significant increases EPEs, particularly southern region. may be helpful exploring disaster-causing processes weather, it provides theoretical basis deriving hazard chain, which more applicable basins long durations.
