Abstract

Precipitation is the main sources of subsurface and surface water in the Tianshan Mountains, which play a vital role in the social and economic developments of Xinjiang, China. Researches showed that precipitation in the Tianshan Mountains is largely affected by climate phenomenon. In this paper, Ensemble Empirical Mode Decomposition (EEMD) and wavelet coherence analysis were used to explore the effects of climate teleconnections at annual to multidecadal scales on precipitation in the northern and southern slopes of the Tianshan Mountains. The results show that the annual scale of ISM strongly impacts the precipitation on both northern and southern slopes. The interannual scales of ENSO and NAO mainly affect the precipitation of the northern slope, and ENSO has a greater influence on precipitation than NAO. The influence of the multidecadal scale of the PDO on precipitation of northern and southern slopes are weak.
