1 year ago 2 year average total energy diagnostics:
dE/dt energy fixer (pBP-pBF) -0.1196 W/M^2
dE/dt parameterizations (pAP-pBP) 0.01945 W/M^2
dE/dt dry mass adjustment (pAM-pAP) 0.3109 W/M^2
dE/dt total adiabatic dynamics -0.1352 W/M^2
dE/dt 2D dynamics (dAD-dBD) -0.08344 W/M^2
dE/dt vertical remapping (dAR-dAD) -0.05173 W/M^2
Breakdown of 2D dynamics:
dE/dt hypervis (dCH-dBH) -0.6536 W/M^2
dE/dt frictional heating (dAH-dCH) 0.5645 W/M^2
dE/dt residual (time truncation errors) 0.005693 W/M^2
dE/dt physics tendency in dynamics (dBD-dAF) 0.155 W/M^2
Dribbling errors (pAM-pBF-(dBD-dAF))0.05571For comparison (1 year averaged energy diagnostics for the ebduget, new energy, run):
dE/dt energy fixer = -0.44 W/m^2 dE/dt dry-mass adjustment = 0.65 W/m^2 dE/dt dynamical core = -0.12 W/m^2
Physics-dynamics dE/dt = -0.44 W/m^2+0.65 W/m^2-0.12 W/m^2 = 0.07 W/m^2
What I see is:
- the dynamical core energy errors do not depend on total energy formula (I think that is expected)
- energy fixer has to fix more with the new energy formula since the dry-mass adjustment has gone from ~0.3W/m^2 to 0.6W/m^2 (dry-mass adjustment has changed due to weightening water vapor, liquid and ice fluxes with their respective heat-capacities rather than the heat-capacity of dry air)
