Реферат: A numerical model of the dynamics of a flat localized region of turbulent perturbations of non-zero buoyancy in a linearly stratified medium has been developed on the basis of the mathematical model, including differential equations for Reynolds stresses transfer and algebraic model of a turbulent flux vector of a scalar. The evolution of a heated tur-bulent spot has been considered. The non-zero buoyancy is the reason of an increase in the geometrical size of the turbulent spot and generation of internal waves of greater amplitude. The generation of the total energy of turbulence is insignificant even in the case when the initial potential energy of a turbulent spot of non-zero buoyancy is comparable to the initial total energy of turbulence in it.
