Based on the observed dust weather occurrence (DWO), precipitation and 10 m wind speed at 23 stations over the Tarim Basin in northwest China and the National Centers for Environment Prediction/National Center for Atmospheric Research reanalysis data during 1961–2015, we have indicated the relationship between the summer DWO over the Tarim basin and South Asian summer monsoon (SASM) and revealed the possible underlying physical mechanisms. Results show that the DWO displays an obvious declining trend during 1961–2015 and has a good relation with precipitation and 10 m wind speed over the Tarim Basin in summer. Meanwhile, the index of SASM well correlates with the summer DWO over the Tarim basin at both interannual and interdecadal time scales. Further analysis of the underlying mechanism related to the impact of the SASM on the DWO over the Tarim Basin in summer indicates that an anomalous cyclone (anti-cyclone) appears in the upper troposphere over Central Asia responding to an...

南亚季风对西北塔里木盆地夏季沙尘天气的影响

根据西北塔里木盆地23个站的观测到的沙尘天气发生（DWO），降水和10 m风速，以及1961-2015年国家环境预测中心/国家大气研究中心的再分析数据，我们指出塔里木盆地夏季DWO与南亚夏季风（SASM）之间的关系，揭示了可能的潜在物理机制。结果表明，DWO在1961–2015年期间呈现出明显的下降趋势，并且与夏季塔里木盆地的降水和10 m风速有很好的关系。同时，在每年的和年代际的时间尺度上，SASM的指数与塔里木盆地夏季的DWO很好地相关。
