DATA-COAMPS-ROMS Coupled Application
- WC12 application 184x179x42, mean resolution dx = 8.5 km and dy = 11.0 km
- COAMPS application 201x204x60 with dx=dy=45 km (coarser), and 214x217x60 with dx=dy=15 km (finer)
- Time stepping: COAMPS 60 s, ROMS 600 s
- Coupling Simulation C01: Using ROMS bulk fluxes parameterization
- Sequential and semi-implicit coupling
- Non nested COAMPS, just coarser grid
- Coupling interval: 600 s, COAMPS exports time-averaged fields
- COAMPS imports SST from DATA and ROMS components
- DATA component reads SST from HyCOM 1/12 dataset, 4500x3298
- ROMS activates BULK_FLUXES, COOL_SKIN, EMINUSP, LONGWAVE_OUT, WIND_MINUS_CURRENT
- ROMS imports dLWrad, SWrad, Pair, Tair, Qair, rain, Uwind, and Vwind
- Coupling Simulation C03: Using ROMS bulk fluxes parameterization
- Sequential and semi-implicit coupling
- Nested (Coarse and fine) COAMPS
- Coupling interval: 600 s, COAMPS exports time-averaged fields
- COAMPS imports SST from DATA and ROMS components
- DATA component reads SST from HyCOM 1/12 dataset, 4500x3298
- ROMS activates BULK_FLUXES, COOL_SKIN, EMINUSP, LONGWAVE_OUT, WIND_MINUS_CURRENT
- ROMS imports dLWrad, SWrad, Pair, Tair, Qair, rain, Uwind, and Vwind
- Coupling Simulation C04: Using COAMPS surface fluxes parameterization
- Sequential and semi-implicit coupling
- Nested (Coarse and fine) COAMPS
- Coupling interval: 600 s, COAMPS exports time-averaged fields
- COAMPS imports SST from DATA and ROMS components
- DATA component reads SST from HyCOM 1/12 dataset, 4500x3298
- ROMS deactivates BULK_FLUXES, COOL_SKIN, EMINUSP, LONGWAVE_OUT, WIND_MINUS_CURRENT
- ROMS imports SWrad, shflux, swflux, sustr, and svstr
