Abstract
The transport of mass and heat in the atmosphere and ocean depends largely on how the turbulence is affected by the combined effects of the density gradient and the shear in the velocity. When there is no shear, the results of RDT (Hanazaki & Hunt, 1996) have shown how the initial conditions determine the subsequent time development of the partition of energy between the potential energy and the kinetic energy. In addition, the change of sign in the vertical density flux with time, which leads to the so called ‘counter-gradient flux ’, could be explained by the simple linear oscillations due to buoyancy effects rather than by any new kind of nonlinear mixing processes.
