Monin-Obdukhov length

The Obukhov length (L) measures the
  • relative importance of mechanical shear-generated turbulence and density-driven (buoyancy) fluxes 
  • can be used to determine the eddy structure of the flow and it provides a measure for the hydrodynamic stability of the boundary layer - it effectively imposes an upper limit on the vertical excursion of fluid particles due to (negative) buoyancy force
