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