Abstract  

Based on  meteorological observation data from 701 meteorological stations in China during 1960-2010, two dust indices, which are Taklimakan Dust Index (TDI) and Gobi Dust Index (GDI), were used to characterize the statistical feature of the dust event occurrence. In general, TDI and GDI both exhibit a sudden decrease in the mid 1980s. Although the intensity of GDI were smaller than the TDIs since 1960s, its inter-annual variability was larger. We also analyzed the differences of atmospheric circulation between years with  high and low dust index values. The results indicated that the low dust index values in Southern Xinjiang was likely caused by the waken Mongolia Cyclone and the thermal low pressure in the Taklimakan region, but that the intensity of Siberia Cold High Pressure and the Mongolia High Pressure became waken was the main mechanism of low dust index values in the Inner Mongolia.

Key words:  dust index      500 hPa geopotential height field      500 hPa wind field      850 hPa wind field      sea level pressure field
