Abstract
A three–dimensional continuous plume model is presented in which along-wind and vertical dispersion are based on an analytic solution of the advection-diffusion equation, while lateral cross–wind diffusion is parameterized by a Gaussian multipli.icative factor. This results in an intermediate approach between the Gaussian Mode 1 and the K Mode 1: it has the simp 1 ic ity of the first and, moreover, can be applied to an atmosphere with inhomogeneous turbulence.Keywords
