review text: An analysis is given of the behavior of perturbations in an exponentially stratified fluid at the final linear stage of their damping within the limits of large time scales. We speak of turbulent motion in the sense that at the start of the linear stage there is a fairly representative set of perturbations of various kinds. Section 1 estimates the role of one viscous transfer process in the evolution of these perturbations, section 2 estimates that of two transfer processes (viscosity with heat conduction or diffusion), and section 3 that of three (viscosity with heat conduction and diffusion or with two types of diffusion). The simplifications made in the analysis rest on interest in the most slowly damped perturbations and on high values of the Prandtl numbers for ordinary fluids.
