EVOLUTION OF HOMOGENEOUS TURBULENCE IN
A DENSITY-STRATIFIED MEDIUM.
2. ASYMPTOTIC ANALYSIS OF FINAL STAGE OF DECAY

The asymptotics of a large evolution time of homogeneous
turbulence in a density-stratified medium is studied. It
is shown that the presence of stratification substantially
changes the attenuation rate of turbulence kinetic energy
and other turbulence characteristics and forms asymptotic
regimes which differ from the case of an isotropic medium.
The effect of the molecular Prandtl number on the final
stage of turbulence decay is studied in detail.
