Numerical modeling of the spread of harmful substances in the atmosphere taking into account terrain

Аннотация

At work, numerical model and algorithm are developed for research, forecasting and making management decision about the process of the spread of harmful airborne substances in the atmosphere. In deriving the mathematical model of the object of the study, the basic weather and climatic factors are taken into account which influence the process of transfer and diffusion of pollutants as well as a significant parameter, the terrain of the region. In the article for solutions of the first and third boundary, the numerical algorithm for the numerical calculations on the computer has been developed. On the basis of mathematical models and numerical algorithms we developed a software tool in high level language, Borland C ++ Builder. The results of numerical calculations are presented as graphics. It is also considered the use of geo-information web-service as information security software modules for settlement.
