摘要：
In this paper, a numerical scheme for solving a system of convection-diffusion-kinetics equations of a mathematical model of transport of small pollutant components with their chemical interactions in the atmospheric boundary layer is presented. A new monotonized high-accuracy spline scheme is proposed to approximate the convective terms. Various approaches to parallelization of the computational algorithm are developed and tested. These are based on a two-dimensional decomposition of the calculation domain with synchronous or asynchronous interprocessor data communications for distributed memory computer systems.
