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.
