Localized stirring in a field of salt-fingers

Wells, M; Griffiths, Ross


In a series of laboratory experiments, a partially mixed patch was produced in thick linear concentration gradients favorable to salt-finger convection. Salt-fingers, which give rise to an up-gradient flux of buoyancy, can reduce and invert the density gradient in the initial imposed patch. This leads to overturning convection within the patch if (a) the ratio of ambient T and S gradients, Rρ αTz/βSz, is near one; (b) the initial imposed turbulence results in a nearly well-mixed patch; and (c)...[Show more]
