A Finite Difference Model on Atmospheric Pollution and its Application

Changjun Zhu, Ming Liu and Wenlong Hao

Journal Title:Nature Environment and Pollution Technology

In view of near-ground atmospheric problem, near-ground atmospheric pollution model was established. Because the applicability of analytical solutions is extremely limited for such conditions, and the distribution and transport of pollutants in air are controlled by geographical conditions, numerical techniques are essential for air pollution modelling. In this paper, finite differential method is used to establish plane two-dimensional numerical model of near-ground atmospheric pollution belt, and truncation errors associated with finite-difference solution of atmospheric pollution were corrected based on the Taylor analysis. The results indicate that this method provides the references for the forecast of pollutants and the management and evaluation of air resources.
