Abstract

The turbulent diffusion model is submitted. The model is based on the similarity theory of random processes and is derived from "the first prin- ciples". The problem about turbulent diffusion of an impurity above an industrial region at specific emission is considered. The general solution of the problem in special case when the emission is a periodically function of time is obtained. 1 Introduction The theory of turbulent diffusion is a basic for the air pollution transport modeling. At the moment the models of turbulent transport are based mainly on the Monin-Obukhov theory of similarity [1] and hypothesis that the eddy diffusivity of an impurity is proportional to the eddy viscosity (Russell et al. [2]; Pugliese et al. [3]). In turn the turbulent eddy vis- cosity is determined from the empirical formulas (Busin
