Monin-obukhov theory
WebThe intent of this study is to investigate the limitations of the Monin–Obukhov similarity theory (MOST) for wind profile extrapolation—particularly its breakdown in stable stratification—and to explore several modifications intended … WebThe Monin-Obukhov similarity theory, which is used to compute these fluxes in numerical models, utilizes the empirical stability correction functions. In the present study, impact of various functional forms of similarity functions on the computation of the surface fluxes under both unstable and stable stratification is analyzed.
