The Depth of the Surface Boundary Layer,

Abstract

The depth of the surface boundary layer of the atmosphere can be related to a characteristic dimension defined by Obukhov as the scaling length L. By using the form of the diabatic wind and temperature profiles, the depth of the surface layer is demonstrated to be proportional to and a function of the slope of the wind profile and the Obukhov length. The methodology was verified using experimental data extracted from the literature. Generally, the surface boundary layer depth approaches the depth of the planetary boundary layer in near adiabatic conditions near sunrise and sunset.
