Allowing for Terrain Irregularity in a Jet-Diffusion Model of Impurity Scattering

Краткое описание

The feasibility of adapting the jet-diffusion model of scattering of an impurity from elevated sources in the atmosphere over an irregular terrain is explored. The cases of impurity scattering over single terrain irregularities, such as hills or some structures, and over a forest and over a city are analyzed in detail. Recommendations on calculating the distribution of concentrations in the ground layer of the air with allowance for the actual topography by appropriate correction of the dispersion values are presented. The method of utilizing potential flows and allowance for transformation of the wind-stream velocity for solving problems of atmospheric diffusion over an irregular terrain is analyzed separately.
