Abstract
Atmospheric transport of salt-dust aerosols is a sophisticated effect mainly depending on the meteorological situation. Since the dried bottom of the Aral Sea is considered as emissions source, precisely the wind removal of aerosol particles is implied here. It should be noted that the wind erosion of the ground cover can be considered as a special case of the hydrodynamics of multiphase flows, which is of particular scientific interest. In this regard, vertical wind profile, which depends on the roughness of the ground cover and the stability of the atmosphere, become to one of essential aspects for outdoor airflow simulations. Thus, the aim of this work is to study the influence of the vertical wind profile on the atmospheric transport of salt-dust aerosols. The results of computational experiments on the airflow characteristics at various heights, values of the ground-level wind speed and the roughness coefficient are presented in the paper. As well as the results of numerical calculations demonstrating the influence of the horizontal and vertical components of the wind speed on the distribution of suspended aerosol particles within the considered area.
