[ecco-support] variables of ECCOv4

[Wang, Ou (329B)]

Hi Ying,

ADVe_TH and DFeE_TH are E-W components rotated from the corresponding variables on v4 native grid (ADVx_TH, ADVy_TH, DFxE_TH and DFyE_TH). To close budget, one should use the latter.

ECCO v4 uses 3rd-order Direct Space and Time (DST-3) advection scheme (see GAD_DST3_ADV_X.F and GAD_DST3_ADV_Y.F). In essences, the formula for advective fluxes is sum of u x theta x area of cell face, plus some higher order terms. DFxE contains the explicit part of all non-advective terms causing the temperature change.

Dear Sir or Madam,
I am Ying, a Ph.D student studying in the CSIRO. Recently, I have been doing some research about the heat budget of the Indian Ocean. However, there some are problem with me. I do not what formula the ADVe_TH and DFeE_TH based on? Is the ADVe_TH calculated by <u*theta>*area of the cell? It didn’t match that, if I calculated based on <u*theta>*area of the cell. So I just wandering the formula of the the ADVe_TH and DFeE_TH. I would greatly appreciate that. Thank you so much.
Sincerely,
Ying.
