[MITgcm-support] Potential energy in MITgcm

[Shevchenko, Igor]

Hi Martin,

Thank you for the answer.
I just thought there might be something about it in MITgcm I missed.

Best regards,
Igor

Hi Igor,

rhethorical question: what is potential energy in a GCM?

This is a bit complicated. You could just intergrate density vertically (and density or density anomaly can be saved via the diagnostics pkg), but you really only want to have available potential density, for which you need a reference state that is difficult (impossible?) to define for general case. So it’s always set-up specific.

Details of the actual computation also depend on details of your configuration (free surface linear/non-linear/r-star, etc.)
