WebMonin–Obukhov similarity theory (MOST) had been laid earlier by Obukhov’s (1946) fundamental article (e.g. see historical survey by Foken, 2006). Among other things Obukhov (1946) proposed a buoyancy length scale L (‘Obukhov length’) which plays a central role in the MOST. Based on dimensional analysis (Pi theorem), the MOST states http://www.atmo.arizona.edu/students/courselinks/spring08/atmo336s1/courses/spring14/atmo579/Boundary_Layer/ATMO_579_files/Bound-Lay%20Meteorol%202406%20Foken.pdf

WebMonin–Obukhov similarity theory (MOST) is the back-bone for coupling the atmospheric model component of numerical models to the underneath surface. MOST applies for homogeneous and stationary conditions, but it is used in ever more complex and heterogeneous configurations. WebMonin-Obukhov Similarity Theory 91 According to MOST [19], any dimensionless characteristics of the turbulence depends only on the 92 dimensionless stability parameter z = z/L where z is the height above the surface and the Obukhov 93 length L that is defined by L u3 k g Q w 0q0 (1)
