Abstract

A new generation of the atmospheric dispersion models is under development in the USA and Europe (Berkowicz et al., 1986; Perry et al., 1994). These Gaussian models employ parametrizations of dispersion coefficients and other variables with physical parameters rather than with stability categories. Seemingly more direct approach to introduction of physical parameters into dispersion models can be based on solution on the advection-diffusion equation. Results of such an approach are presented in this paper; ways of generalization of the developed flat-terrain model for account of building-downwash effects are also discussed here.
