Abstract:Based on data from the China Meteorological Administration's Yearbook of Tropical Cyclones, this study analyzes the spatiotemporal characteristics of typhoon precipitation (TP) in the Huanghai and Bohai Sea Region (30–50°N, 110–130°E) during 1961–2020. The results show the following: (1) ?Spatial distribution?: The 60-year averages of TP, number of typhoon precipitation days, number of typhoon rainstorm days, number of precipitation-producing typhoons, and contribution rate of typhoon to total precipitation all exhibit a maximum center along the northern coast of Zhejiang Province, decreasing northward and inland. In contrast, the spatial differences in typhoon rainfall intensity and extreme daily precipitation were relatively smaller. Specifically, northeastern China (Dongbei region) and the circum-Bohai areas show higher values of typhoon single-day precipitation intensity (T-SDPI), mean process TP, and typhoon contributions to top 1% historical extreme daily precipitation. (2) ?Interannual variation?: Over the 60-year period, the number of precipitation-producing typhoons affecting the Huanghai and Bohai Sea Region increased significantly, while annual TP displayed a "decreasing-then-increasing" trend. Notably, during 2012–2020, the regional mean TP over the Huanghai and Bohai Sea Region and area mean TP in Jilin, Jiangsu, Anhui, Hubei, and northern Zhejiang were significantly higher than that before 2012.(3) ?Seasonal distribution?: TP in the Huanghai and Bohai Sea Region predominantly concentrated between June and October, peaking in August, followed by September and July. From 2012 to 2020, with the significant increase in annual mean TP, spring TP disappeared, while the feature that early autumn (September–October) TP was stronger than early summer (June–July) TP became more pronounced. It suggests an overall tendency for TP in the Huanghai and Bohai Sea Region to shift toward autumn within the annual cycle.
