Droughts are long-term natural disasters and encompass many unknown factors. Herein, yearly seasonal standardized precipitation evapotranspiration index (SPEI) values were calculated by analyzing monthly temperature data from 1971 to 2020. A cloud model was employed obtain the spatiotemporal variations in distribution of drought weather.
