Abstract:Based on the thermodynamic theory of convective plumes and vortices in the atmosphere boundary layer and by using the observational data in the Taklimakan desert and surroundings, the dust aerosol emissions from the convective plumes and vortices are estimated with annual average of 4.0×106t and the maximum of 5.0×106t with an equivalent contribution to dust aerosols from dust storms over the Taklimakan desert. Depending on the seasonal cycles of solar radiation intensity, the dust aerosol emissions from the convective plumes and vortices vary with the changes of surface temperature.
