[MITgcm-support] energy conservation

[Angela Zalucha]

Hi,

I am trying to verify conservation of energy in the MIT GCM, and would like to 
confirm that, in the absense of an external heating term, the dynamical core 
conserves energy.  The reason for this question is I am running essentially the 
Held & Saurez 1994 test case, with dynamics and external heating turned off, 
and find that the Shapiro filter acts as a lateral diffusion that creats a 
nonzero, in fact overwhelmingly large, lateral energy transport.  I have copied 
my data.shap file below.  Note that deltaT=15. and rSphere = 1180.E3.

Thanks,
   Angela
