Abstract
A three-dimensional numerical model of atmospheric hydrodynamics, transport and photochemical transformation of gas-phase pollutants and aerosol dynamics is considered. New particle formation occurs via binary homogeneous nucleation of sulphuric acid and water vapor, proceeding under the conditions of temperature and humidity fluctuations. The kinetic processes are described by multidimensional equations of condensation and coagulation, where the size-distribution function is given explicitly. Wind flow fields and turbulent characteristics are calculated from the mesoscale nonhydrostatic model of atmospheric hydrodynamics over complex topography. A series of numerical experiments are performed aimed at modeling the photochemical air pollution and aerosol dynamics in two specific regions as well as formation of sulfate aerosol particles in the northern hemisphere. A comparison is given for calculated and measured ozone concentration data.
