Abstract
In this work an eddy diffusivity for the residual layer is proposed. The analysis is based on two
main physical mechanisms responsible of the turbulence transfer: the turbulence of the recently
decayed mixed layer and the shear-driven turbulence. The resulting eddy diffusivity can be written
as a sum of these two contributions.
1 Introduction
In the last thirty years, a variety of models have been developed to simulate
plume dispersion in convective and stable boundary layers (CBL and SBL).
However, the modeling of the dispersion of contaminants in the residual layer
(RL), a weakly stratified remnant of the daytime mixed layer remaining above the
nocturnal boundary layer
