摘要：

Numerical simulation of the dynamics of homogeneous turbulence of a stably stratified fluid in the presence of a vertical constant-density gradient was carried out. The second-order model which is universal with respect to turbulent Reynolds and Peclet numbers and molecular Prandtl number is applied to the numerical simulation of the dynamics of the velocity and density field parameters up to the final stage of der-ay. At small evolution times Ntau, the results of similation are compared with the familiar experimental data. The structure of a 'relict' turbulence was investigated for the molecular Prandtl numbers corresponding to air and sea water.
