Gledzer, I. Granberg, O. Chkhetiani] Asymptotics for the mass concentration of finely dispersed aerosol are obtained on the basis of in situ measurements in a desert in the Caspian region and estimates of hydrodynamic parameters in the viscous thermal boundary layer near the soil surface. In the problem under consideration, the dynamic velocity (friction speed) and the temperature drop in the thermal boundary layer are external parameters. The model of a porous soil layer, in which the air dynamics is described with the use of the Darcy equation, is considered a possible mechanism of aerosol export. The estimates of the critical parameters at which sand particles thermally roll over in soil pores are obtained. Pleiades Publishing, Ltd., 2010 Gledzer E.
