buoyant subrange

A range of turbulent eddies in a stably stratified atmosphere, too small to be influenced by shear but large enough to be affected by buoyancy.

Dimensional considerations give a power law dependence of energy versus wavenumber, or spectral slope, of -11/5.
See turbulence spectrum.
