buoyancy subrange
From Glossary of Meteorology
For a statically stable atmosphere, the portion of the turbulence kinetic energy spectrum at wavelengths longer than those in the inertial subrange, where buoyancy causes the spectral energy S to change with the -3 power of wavenumber k:
In conditions of strong static stability, turbulent motions are strongly suppressed in the vertical and have characteristics similar to gravity waves.
where N is the Brunt–Väisälä frequency.
In conditions of strong static stability, turbulent motions are strongly suppressed in the vertical and have characteristics similar to gravity waves.
