| Short definition of Diapycnal eddy diffusivity (Diapycnal eddy diffusivity ) |
|---|
| Diapycnal eddy diffusivity (for buoyancy) is defined from the buoyancy flux and the background density gradient |
This is the common definition for Diapycnal eddy diffusivity, but other definitions maybe discussed within the wiki.
