A Local Parameterization Scheme forσwunder Stable Conditions

Abstract
Turbulence in stable conditions is local, that is, it is locally defined by small eddies. A local formulation for σw based on a level 2 approximation of Mellor and Yamada (1974) is proposed. The proposed formulation is able to describe the nondimensional profile of (σw/U∗)2 against Z/H consistently when compared with the Minnesota observations, where H is the height of the turbulent stable boundary layer.
