[MITgcm-support] advective fluxes and transports

[Baylor Fox-Kemper]

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
