[MITgcm-support] online calculation of energy flux

[Robert Nazarian]

Hi Peng,

Yes, I have already derived some equations for calculating the energy flux (but this will be done at every time step and at every grid cell). What I'm trying to do is actually incorporate these calculations into the source code so that the calculations can be done online rather than offline. Is there a straightforward diagnostic that's already written which I can add this to or should I be creating my own diagnostic? If so, which subroutine should it be included in?

Thanks,
Rob

Hi Robert,
If I understand correctly for your case, I would suggest you use the following formular:
mean(u'p')=mean(up)-mean(u)mean(p) instead of finding mean(u'p') directly.

Hi Robert,

You should state that it's the product u'p' that you want, and you want to do it online so that you can calculate time-averages. Otherwise you might get a response that u is already output, as is p, so why do you need to add anything?

Hi,

I’m trying to add an online evaluation of u’ and p’ to the source code to calculate the energy flux. Is there a particular diagnostic that would be best to do this in? If not, is there a particular subroutine that’s ideal to write such a diagnostic? Previously, I did these calculations offline but am hoping to incorporate it into the code itself.

Thanks,
Rob
