Abstract:

Modeling the dispersal of atmospheric aerosol over an industrial center is performed based on the system of equations for dynamics of the atmospheric boundary layer including the equations for the wind velocity components, temperature, humidity, and balance equation for the energy fluxes on the underlying surface. Cities are sources of aerosol pollution of the atmosphere. They can be characterized by a strong thermal inhomogeneity what leads to formation of the specifically urban caps of air pollutants. We discuss some specific features revealed to occur in the aerosol concentration diurnal behavior under different meteorological conditions.
