Buoyancy driven circulation

Motivated in part by the review article of Hughes and Griffiths (Annual Reviews of Fluid Mechanics 2008, Horizontal Convection), in part by an email thread throughout the summer and in part by the Paparella and Young "anti-turbulence" theorem (JFM 2002), we consider idealized horizontal convection focusing on energetics and bounds for the energy transfer rates, in particular the rate of irreversible mixing and buoyancy variance destruction.

Bill Young presented a version of this work at the Sandstrom Symposium at Stockholm University and I also presented a version at the Newton Institute. A pdf of my keynote presentation, along with the revised MS is attached below.
