Abstract: Nocturnal boundary-layer data from the Wangara and Voves experiments are analyzed. The lower part of the nocturnal inversion layer normally appears to be turbulent but strongly stratified. The upper thicker part of the ...

Abstract: The depth of the nocturnal boundary layer, modeled by diagnostic functions of surface fluxes, is only weakly related to ?observed? depths estimated from observed profiles of either wind or temperature as has been shown in ...

Abstract: The quasi-normal theory modified by the clipping approximation is used to construct a numerical model of vertically inhomogeneous turbulence in a Boussinesq fluid. The pressure-correlation terms are expressed according to ...

Abstract: A modification of the quasi-normal theory is proposed for the study of inhomogeneous turbulent flows. In this approximation realizability conditions for third-order correlations are enforced. These conditions are based on ...

Abstract: A high-order model is proposed for the study of the 24 h evolution of clear planetary boundary layers. The model includes the rate equations of correlations up to the third order, as required for an accurate description ...
