I'm playing around with vertical mixing in the hopes of preventing deep convection in the Weddell Sea. It's a delicate balance between having enough vertical mixing that brine doesn't accumulate in the mixed layer, but not so much that the Winter Water layer gets mixed out.
There are a lot of options for LMD_MIXING and I'm having trouble finding documentation on what each of them does, which ones should be run together, etc. This is my setup right now:
Code: Select all
#define LMD_BKPP
#define LMD_CONVEC
#define LMD_DDMIX
#undef LMD_NONLOCAL
#define LMD_RIMIX
#undef LMD_SHAPIRO
#define LMD_SKPP
Switching off LMD_NONLOCAL seems to help at least a little (which makes sense, it seems to be an instantaneous convective adjustment?) I have to keep LMD_SHAPIRO off otherwise the model blows up (although this decision was made ages ago before a few bugs were fixed, maybe it would be okay now).
I'd appreciate any suggestions or links to documentation. Thanks!
