MODELING OF ATMOSPHERIC AIR POLLUTION
In modern environmental conditions modeling of air pollution is an actual problem. The simulation of the state of atmospheric air quality using various mathematical approaches describing the physicochemical processes that are modeled depending on the type of pollution, emission parameters, meteorological, topographical and other conditions influencing the dispersion of pollutants is considered. The key requirements for models of atmospheric air pollution are given. The stages of construction and classification of atmospheric air pollution models are considered. One of the types of atmospheric air pollution models are models that have as their basis a mathematical description of the physical processes taking place in the atmosphere. Similar models are based on the solution of the equation of turbulent diffusion. The solutions of the equation for describing the phenomenon of transport and diffusion of the pollutant for the models of «coil», «torch», «box» and «finite-difference» model are considered. The advantages and disadvantages of these models are described. The software implementation of the «torch» model is described.
