[MITgcm-support] Buoyancy anomaly

[Laure Grignon]

Hello,
Do you use a hydrostatic or non-hydrostatic configuration? If hydrostatic,
you¹ll need to parameterise these effects (p232 of the MIT manual, on ocean
convection, for the simplest ways of doing it).
If you've already done this, I don't know...
Laure
