Present study investigates the dominant modes of interannual variability in precipitation over the Hengduan Mountains (HM) during rainy seasons. The leading two empirical orthogonal function (EOF) modes of HM precipitation explain 28.4 and 13.9% of the total variance, respectively. Positive EOF1 phase features enhanced precipitation anomalies over the southern HM, and a dipole structure with wet anomalies occupying large areas...

The present study investigates the interannual variability of precipitation over the Hengduan Mountains (HMs) during rainy season based on daily precipitation dataset of 151 meteorological stations. More HMs precipitation is associated with an anomalous lower level cyclonic circulation over the northern South China Sea (SCS) and the upper level Silk Road pattern (SRP)‐like geopotential height anomalies. Along the north flank o...
