On parameterizing inclined stable boundary layers

The mixing length-scale for the stable atmospheric boundary layers, i.e. the characteristic mixing length in the "z-less" regime, as often parameterized in mesoscale models with higher-order closure turbulence parameterization schemes, is assessed. A better treatment of the balance between shearing and buoyancy effects on the "z-less" mixing length-scale appears as a necessity. The importance of this detailed subject is manifold, ranging from improving numerical weather prediction (NWP) models, moisture exchange estimations over complex terrain, to betterment of air-pollution and wind-energy related calculations. This short article is a call for improvements in parameterizing the mixing length- scale, which appear necessary nowadays having increasingly refined horizontal and vertical resolution in NWP models.
