Large‐eddy simulation and parametrization of the baroclinic boundary‐layer

Large‐eddy simulations of the non‐entraining dry boundary‐layer, in which the geostrophic wind varies with height, are described. Results are presented for various turbulence statistics, and the large‐eddy model results are used to evaluate the performance of two simple closure‐models. It is shown that the performance of these models is not significantly degraded, in either neutral or convective conditions, by the presence of shear in the geostrophic wind.
