Available Potential Energy and Irreversible Mixing in the Meridional Overturning Circulation

Hughes, Graham; Hogg, Andrew; Griffiths, Ross

Description

The overturning circulation of the global oceans is examined from an energetics viewpoint. A general framework for stratified turbulence is used for this purpose; first, it highlights the importance of available potential energy in facilitating the transfer of kinetic energy to the background potential energy (defined as the adiabatically rearranged state with no motion). Next, it is shown that it is the rate of transfer between different energy reservoirs that is important for the maintenance...[Show more]
