[MITgcm-support] advective fluxes and transports

[Dimitris Menemenlis]

Baylor, for computation of transports, which diagnostic should one use: ADVx_TH, 
UTHMASS, or UVELTH?  To date I have been using UTHMASS but from your description 
below it sounds like it would be more accurate to use ADVx_TH ?  D.


> Hi Paola, UVELTH is just the correlation of the U and theta fields, with
> temperature appropriate interpolated.  ADVx_TH is the advective flux, which
> can include things like the variable grid box size with nonlinear free
> surface, shaved cells, etc, as well as the flux-limiting corrections.  UVELTH
> will be equivalent to ADVx_TH only with centered 2nd-order advection and
> simple vertical discretization/boundary conditions. Cheers, -Baylor
