Abstract
In the so called E - ε turbulence model, an eddy viscosity is evaluated from turbulent kinetic energy E and energy dissipation ε. Although still a first-order closure method in its simpler form, the E- ε model yields eddy viscosity for complex turbulent flows without a prior prescription of a length scale needed in so-called mixing-length models. The E - ε model has been successfully applied to many flow problems in engineering applications for non-rotating boundary layers. In this paper, the E - ε method is extended to the atmospheric boundary layer for which a modification of the dissipation equation is found to be necessary in order to give results comparable with observational data.
