Abstract:Central Asia is located in the interior of Eurasia, in the key area of westerly wind control.With accelerating global warming in recent years, observations and simulations show a trend of warming and humidification in Central Asia.SST anomalies in the North Atlantic induce atmospheric vorticity anomalies, which propagate anomalies influencing large-scale circulation and vertical motion in Central Asia via Rossby wave activity, leading to an increase in precipitation anomalies.Simultaneously, the SST anomalies in the equatorial Pacific Ocean and the North Indian Ocean cause abnormal water vapor transport from the Arabian Peninsula to Central Asia, as well as the westerly-monsoon synergy, the remote correlation phase transition of the Silk Road, the changes of land surface type, local circulation and soon, which all contribute in varying degrees to the warming and humidification process in Central Asia.This paper aims to outline the main influencing factors and mechanisms of precipitation anomalies in Central Asia in the past 20 years, and to propose future research directions based on previous research.
