Large Eddy Simulations of the turbulent katabatic flow developing along a hyperbolic tangent slope in stable atmospheric boundary layer

Résumé

Large Eddy Simulations of the turbulent katabatic flow developing along a hyperbolic tangent slope are performed in the context of stable atmospheric boundary layer. The effects of ground surface boundary conditions and initial temperature stratification are analysed. It is shown that, even for stratification up to N = 0.020 s −1 , that is to say the upper limit for on site measurements, turbulent structures develop and turbulent heat fluxes and turbulent shear stresses increase in the downslope jet close to the ground surface. Mixing might be increased, a property of direct importance for pollution prediction.
