Rapidly growing ocean data availability is fueling the establishment of new regional and coastal ocean models and operating systems, while growing global climate disruption necessitates robust long-term simulations of regional and coastal ocean processes and hazard risks. This work explains, for the first time together in one place, solutions for overcoming three fundamental, tide-related technical challenges in regional and coastal ocean modeling: (1) automatic generation of tidal harmonic forcings from coarser tidal constant databases; (2) perpetual generation of interannual tidal predictions inside hydrodynamic models, such as in the Regional Ocean Modeling System (ROMS); and (3) producing ocean model harmonic constant forcing data using tide models. A modified tidal prediction code (set_tides.F) for continuous multi-decadal simulations in ROMS is also provided as a practical solution to the second challenge, while the complete suite of techniques explained herein allows researchers to avoid tide-related errors in establishing regional and coastal ocean models and operation systems, and to harmonically analyze their output data.
