A numerical model of passive scalar dynamics in turbulent wakes of bodies of revolution in a linearly stratified medium is constructed. To describe the flow we use a three-dimensional parabolized system of equations of motion, continuity, incompressibility, turbulent energy transport, dissipation rate, averaged concentration and dispersion of passive scalar concentration fluctuations. Computational results demonstrate the behaviour of passive scalar characteristics both for momentumless wake and in the wake behind a towed body.
