Using a numerical model that includes a system of averaged hydrodynamic equations in the Oberbeck–Boussinesq approximation, differential equations for the Reynolds stress transfer and dissipation rate, a numerical model of the evolution of a flat turbulent spot in a turbulized stratified medium (degenerate background turbulence) is constructed. The components of the mass flux vector and the variance of density fluctuations are found from algebraic presentations of the local equilibrium approximation. Numerical modeling of the evolution of the turbulent mixing zone and the internal waves generated by this zone in a turbulized linearly stratified medium is performed. The calculation results demonstrate a significant effect of background turbulence on the development of the turbulent spot and internal waves generated by the spot. A large-scale turbulent background leads to generation of internal waves of significantly lower amplitude.
