Energy spectra of stably stratified turbulence

We investigate homogeneous incompressible turbulence subjected to a range of degrees of stratification. Our basic method is pseudospectral direct numerical simulations at a resolution of $102{4}^{3} $. Such resolution is sufficient to reveal inertial power-law ranges for suitably comprised horizonta...
