Web10 apr. 2024 · The Monin-Obukhov Similarity Theory (MOST) is a cornerstone of Earth observations and models. It defines a set of functions that are commonly used to … Monin–Obukhov (M–O) similarity theory describes the non-dimensionalized mean flow and mean temperature in the surface layer under non-neutral conditions as a function of the dimensionless height parameter, named after Russian scientists A. S. Monin and A. M. Obukhov. Similarity theory is an empirical … Meer weergeven The Obukhov length $${\displaystyle L}$$ is a length parameter for the surface layer in the boundary layer, which characterizes the relative contributions to turbulent kinetic energy from buoyant production and shear … Meer weergeven Several functional forms have been proposed to represent the universal functions of similarity theory. Because the Obukhov … Meer weergeven M–O similarity theory, albeit successful for surface layers from experimental validations, is essentially a diagnostic empirical theory based upon local first order … Meer weergeven M–O similarity theory parameterizes fluxes in the surface layer as a function of the dimensionless length parameter $${\displaystyle \zeta =z/L}$$.
