Modelling the depth of the stable boundary-layer

A simple prognostic model of the depth of the stable boundary layer is developed which includes both the possibilities of growth due to entrainment and decreasing depth associated with turbulence decay. The model is designed to avoid requirement of surface fluxes and instead uses information on profiles of mean wind and temperature. Resulting coefficients for the model are estimated by comparisons with existing studies in the literature and comparison with Wangara data.On leave from the Dept of Atmospheric Sciences, Oregon State University, Corvallis, Oregon 97331, U.S.A.
