Interannual variation in summer extreme precipitation over Southwestern China and the possible associated mechanisms
Abstract This study explores the spatial–temporal variations in summer extreme precipitation over Southwestern China (SWC). The frequency of summer extreme precipitation (FEP) has exhibited strong interannual variation with slightly strengthened intensity in recent decades. The associated anomalous...
