[MITgcm-support] nonhydrostatic convection advice?

[Ryan Abernathey]

Scott,

Simulating buoyancy-driven open-ocean convection has been one of the most
successful applications of MITgcm. There is a tutorial about it:
http://mitgcm.org/sealion/online_documents/node119.html
While the scales are considerably larger in that tutorial (DX = 50m), the
overall purpose and parameter regime (i.e. non-hydrostatic, no
parameterized convection) are probably similar to your problem. I would
start from that tutorial and adapt it to your needs. You will probably want
to use smagorinsky viscosities:
