How do we put tides in GCMs?

How do we put tides in GCMs?

The accuracy of surface elevations in forward global barotropic and baroclinic tide models, Arbic et al, 2004, doi:10.1016/j.dsr2.2004.09.014 lists 10 different parameters that need to be set.  The anomalistic month appears as Mm, but geoenergymath/WHUT's Tidal Model of ENSO also requires the tropical and draconic numbers.



The limitations, computational expense, and difficulty in achieving this is probably best spelled out by reading Concurrent simulation of the eddying general circulation and tides in a global ocean model, Arbic et al, 2010,  https://doi.org/10.1016/j.ocemod.2010.01.007  pre-print pdf
