Global space-time patterns of sub-daily extreme precipitation and its relationship with temperature and wind speed

Abstract Sub-daily extreme precipitation events can present significant risks such as flooding and soil erosion. Yet the space time pattern of such events on a global scale and their relationships with temperature and wind speed are not well understood. Based on over 9000 global meteorological stations and multi-source weighted-ensemble precipitation covering the warm seasons of 1980–2022, the characteristics and trends in sub-daily extreme precipitation (3 h time interval) were examined and their relationships with temperature and wind speed were explored across global major river basins. The results revealed a similar spatial pattern in the annual frequency, intensity, duration, and total amount of 3 h…
