The intensification of global climate change and regional human activities has led to an increase in the frequency and intensity of extreme precipitation, posing significant challenges to regional sustainable development. Using daily precipitation observation data from 108 meteorological stations during 1960-2020, the spatiotemporal distribution characteristics of extreme precipitation in the Dongting Lake Basin (DLB) are revealed, and the mechanisms driving extreme precipitation variation in the DLB are investigated. The results showed that with the increase in the frequency, intensity and am...
