Short definition of Diapycnal eddy diffusivity (Diapycnal eddy diffusivity Kρ)
Diapycnal eddy diffusivity (for buoyancy) is defined from the buoyancy flux wρ and the background density gradient ρz

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

Osborn 1980 [1]showed that the buoyancy eddy diffusivity Kρ=wρ¯ρ/z could be reduced to Kρ=ΓϵN2
