Short definition of Diapycnal eddy diffusivity (Diapycnal eddy diffusivity [math]\displaystyle{ K_\rho }[/math])
Diapycnal eddy diffusivity (for buoyancy) is defined from the buoyancy flux [math]\displaystyle{ \bar{w'\rho'{ }[/math]

This is the common definition for Diapycnal eddy diffusivity, but other definitions maybe discussed within the wiki.

Osborn 1980 showed that [math]\displaystyle{ K_\rho =\frac{\bar{w'\rho'}}{\partial \rho/\partial z}\Gamma \epsilon N^{-2} }[/math]
