Abstract
We have developed a downscaled operational oceanographic system for the coastal waters of Korea using a wave-current coupled model. The operational modeling system comprises of coastal circulation model ROMS coupled with wave model SWAN, inter-nally coupled sediment transport model and externally nested water quality model. The hydrodynamic variables such as sea surface elevation, currents, temperature, salinity, storm surge height, and wave information are predicted twice a day in the 72 hours base. The coastal information system which is based on web-GIS system provides predicted results with real-time monitoring data for dissemination to the public and validation of operational model results using various visualization techniques. The wave coupled modeling system uses a meteorological model WRF for the atmos-pheric forcing, a regional tide model NAO.99jb for the tides, and a eutrophication model CE-QUAL-ICM for the water quality. The surface forcing for the operation model ROMS is derived from the predicted results of the operational WRF which has been forecasted for the East China Sea. The open boundary condition for the down-scaled ROMS and SWAN is nested with the predicted results of operational modeling system which use data assimilation for the East China Sea. The previous results simulated 12 hours before are used as an initial condition for the operational oceanographic system., inter-nally coupled sediment transport model and externally nested water quality model. The hydrodynamic variables such as sea surface elevation, currents, temperature, salinity, storm surge height, and wave information are predicted twice a day in the 72 hours base.
