A length scale for the description of turbulent flows under stable stratification, defined as the square root of the ratio between the dissipation rate of turbulent kinetic energy and the third power of the Brunt–Väisälä frequency.
In flows where turbulence and wave motion are simultaneously present, the inverse of the Ozmidov scale defines the buoyancy wavenumber, which separates the buoyancy subrange from the inertial subrange.
