Determination of the Similarity Theory Scaling Parameters from the Vertical Gradients

Abstract

Dynamic similarity of flows theory as applied to the surface boundary layer of the atmosphere must be treated as an interwoven quardrapartite function of trivariant orthoginal turbulent motion, the thermal structure and associated vertical gradients, evaporation at the interface, and vertical transport of water vapor with respect to the specific humidity as a function of height. Physical studies of the surface layer are typically conducted with respect to the buoyant heat flux and the momentum flux. Buoyancy is associated with the sensible and latent heat fluxes. The key parameters for establishing the vertical fluxes are the scaling velocity, scaling temperature, and scaling humidity. An interpretation of the similarity theory developed from the basis of the mean value theorem of calculus allows evaluation of the scaling parameters, without utilizing the mathematically complex diabatic influence functions, but directly from the vertical gradients of wind, temperature, and specific humidity
