Abstract
Modeling the distribution of pollutants in the atmosphere is one of the most important tasks in environmental research and environmental protection. The advection-diffusion equation is widely used to study this process. The accuracy of the numerical solution of problems formulated on the basis of the advection-diffusion equation is largely determined by the method of approximating terms that describe the effects taken into account, including transport, turbulent diffusion, absorption of impurities, properties of impurity particles, terrain, etc. In this work, attention is focused on a number of issues related to the construction of a mathematical model of the process under study, the development of a numerical algorithm for solving the problem based on the Crank-Nicholson difference scheme, increasing the efficiency of the algorithm by parallelizing computational procedures, as well as analyzing the accuracy and convergence of the numerical method used in relation to solving the problem of pollutant propagation in the atmosphere.
