Central Asia is located in the arid zone sensitive to climate change. It is one of the areas with the most serious water scarcity and giving great regional and global contributions of dust aerosols. In this study,we used aerosol optical depth (AOD) and cloud data from MODIS on board the Terra satellite and precipitation data from TRMM to study spatial and temporal characteristics of aerosol-cloud-precipitation interactions. The results showed that during 20022013,AOD in Central Asia was in a rising trend while cloud optical depth (COD) showed a decreasing trend with greater decrease in winter. Seasonally,AOD was high in spring and summer and low in autumn and winter while COD was significantly higher in winter than the other seasons. Regional and seasonal cloud water path (CWP) showed an overall downward trend,and the most significant decrease was found over Tarim Basin with the annual change rate of - 6.607%. By calibrating the monthly precipitation data of TRMM using the measured rainfall data,it was found that precipitation in Xinjiang was mostly concentrated in summer,followed by spring and autumn. In comparison,no significant seasonal difference in precipitation was found in the Aral Sea region. Precipitation over central Asia showed an increasing trend,and the increase was the most significant in winter. Furthermore,AOD was negatively correlated with COD. It has a complex relationship between AOD and CER by the influence of water vapor. CER was negatively correlated with AOD in the case of lower water content of clouds while positively correlated at higher water content. CWP reduced with the increase of AOD,and the sensitivity was the highest in fall and lowest in winter. The relationship between aerosols and precipitation was complex. Generally speaking,aerosols suppressed precipitation in Central Asia.
