The role of turbulent mixing in an overturning circulation maintained by surface buoyancy forcing

Stewart, Kial; Hughes, Graham; Griffiths, Ross


The role of externally imposed rates of small-scale mixing in an overturning circulation forced by differential surface buoyancy fluxes is examined in a laboratory experiment. The circulation occupies the full volume and involves a dense turbulent plume against the endwall and a broad upwelling throughout the interior. For strong externally imposed stirring, turbulent diffusion is the primary means of vertical density transport in the flow, and the dependence of the equilibrated circulation on...[Show more]
