Tidal Forcing

Description of Tidal Forcing in ROMS

Tidal Forcing Files in ROMS

Tidal forcing in ROMS is currently

1. Download the desired tidal constituent database and associated software.
2. Interpolate the tidal constituent database to the desired ROMS grid.
3. Verify all open boundary grid cells contain valid data.
4. The phase of the u/ v/ zeta components of the tidal constituents should be shifted to the appropriate reference time(t=to).ocean.in
5. Convert the amplitude/phase information to tidal ellipse parameters, if necessary.
6. Export tidal ellipse parameters to a ROMS netcdf forcing file.
