Abstract Rainfall erosivity is an essential factor affecting soil erosion, which expected to change under global climate change. Despite the existence of numerous rainfall models, there remains a scarcity research focusing on accuracy multi‐time scale models. In this study, subtropical regions central China (Hubei Province) were selected, where simulation performance six widely employed models was investigated using daily precipitation data from 70 meteorological stations spanning 2000 2020. Using optimal model, Kriging interpolation and Mann–Kendall test revealed significant temporal spatial variations in density. The results show that: (1) model more suitable for simulating Hubei Province. (2) mean annual Province 5894.25 MJ·mm·ha −1 ·h ·a , with large across regions. (3) density showed differences between different seasons, erosion most likely occur summer (June, July August). (4) distribution pattern highly consistent: long‐term high levels Xianning City, southeastern Province, risk high. findings study offer valuable insights into selection mountainous hilly areas provide reference assessing formulating control measures.
