Abstract

Abstract: Influence of East Asian summer monsoon (EASM) and South Asian summer monsoon (SASM) on summer precipitation in Qinghai-Tibetan Plateau was evaluated, based on dataset CRU_TS4.0, East Asian summer monsoon index (EASMI), and South Asian summer monsoon index (SASMI). By using partial correlation method, the tempo-spatial pattern of summer precipitation in the region was also examined. The results showed that SASM was associated with much larger area than EASM.SASM was positively correlated with precipitation in part of the southern plateau,while was negatively correlated with the middle, the north, and the west of the plateau. Positive correlation between EASM and precipitation was found in Qaidam Basin and surrounding regions.

Key words: East Asian summer monsoon, South Asian summer monsoon, CRU_TS4.0 data, partial correlation analysis, summer precipitation in Qinghai-Tibetan Plateau
