Abstract: In this paper a slab model for horizontally homogeneous, stable boundary layers is developed, where variations in mean quantities at the boundary-layer top and in mean shear are accounted for. A rate equation for the ...

Abstract: In this paper we develop an abbreviated model for the pressure-gradient velocity correlation terms in the equations for the Reynolds-stress components in the neutral boundary layer. The model contains three terms: a nonlinear ...

Abstract: The budget of turbulent kinetic energy at the base of the inversion which caps the daytime atmospheric boundary layer depends on the lapse rate of potential temperature in the air aloft. The principal gain term in the ...

Abstract: A second-order modeling technique for stratified turbulent flows with application to buoyancy driven mixed layers is presented. The models of pressure terms, dissipation and destruction of temperature variance are to a ...
