Abstract

Gobi Lakes Valley is located in central Mongolia which is considered to be one of the regions where dust storms occur most frequently in Mongolia. We are planning to clarify both erodibility and erosivity in the valley. To accomplish this objective, we have started field observations of meteorology, soil thermal and moisture properties, and dust concentrations at two locations in the valley. In addition, we are estimating the spatio-temporal distribution of soil moisture and vegetation indices, and the meteorological conditions at times when dust storms occurred over the valley and the surroundings. Results of the above analyses will be validated using the observational data and open-to-public satellite and meteorological data such as the Global change observation mission-C/Second generation global imager (GCOM-C/SGLI) and the SYNOP (Synoptic surface observation). Some preliminary results of this study have been obtained so far. One is the threshold wind speeds as a function of soil moisture at multiple locations in the Gobi Lakes Valley and the surroundings are almost the same as those of Tsogtovoo, Umnugobi, which were estimated in a previous study. The other is that occurrences of strong wind accompanying dust storms correspond to frequent cold-air advection coming from the northwest side covering the valley. We will finally estimate erodibility and erosivity over the Gobi Lakes Valley comprehensively as a goal.
