Abstract: An integral parameterization of the dispersion coefficients σy and σz in a shear?buoyancy-driven atmospheric boundary layer is developed by using a model for the frequency spectrum of eddy energy. The formulation relies ...

Abstract: A new formulation for the lateral dispersion parameter is presented. The model is valid for unstable atmospheric conditions and based on the turbulent kinetic energy spectra and Taylor diffusion theory. It has been tested ...

Abstract: An analytical method to evaluate the Lagrangian length scales for a turbulent planetary boundary layer (PBL) under stable and convective conditions is described in this paper. The method is based on the Taylor's diffusion ...
