Abstract:Accounting for the current knowledge of the Convective Boundary Layer (CBL) structure and characteristics, a new formulation for eddy diffusivities has been derived, to be used in atmospheric dispersion models. Expressions are proposed for eddy diffusivities depending on source distance for inhomogeneous turbulence calculated directly with the Batchelor theory. The classical statistical diffusion theory, the observed spectral properties and the observed characteristics of energy-containing eddies are used to e… Show more
