Annotation

A numerical two-dimensional hydrodynamic model was used to describe the influence of forest belts of different sizes on turbulent transport of SO$_2$ within the atmospheric surface layer. The results of the model calculations showed that the presence of a forest belt results in an substantial reduction of the horizontal SO$_2$ flux due to the decrease of the wind speed and the absorption of SO$_2$ by tree crowns. The extinction coefficient of SO$_2$ flux increases with an increase in the forest belt size and decrease with the pollution source height.
