Abstract
A method to evaluate dispersion parameters in a shear dominated stable
planetary boundary layer is described in this paper. The method is based on the
local similarity and Taylor's diffusion theory. The model indicates that in the
lower half of the stable boundary layer the turbulence structure is nearly
homogeneous. The present analysis allows us to conclude that the statistical
diffusion theory can reproduce the contaminant dispersion in a stable
turbulence described by the local similarity theory.
1 Introduction
In the last twenty years, there has been a wide development of plume
dispersion models in a convective boundary layer. However, the modelling o
