Abstract
This operational coastal modeling system uses ocean model ROMS (Warner et al., 2008) coupled with a wave model SWAN for the hydrodynamics and waves, a meteorological model WRF for the atmospheric surface 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 operational model is derived from the predicted results of the atmospheric model WRF which has been forecasted for the East China Sea. The open boundary condition is nested with the predicted results of data assimilative operational model ROMS which has been in operation for the Yellow Sea with 9 km resolution. For restarting the operational model, the model uses the previous results simulated 12 hours before as an initial condition. The hydrodynamic model ROMS has been calibrated with tidal surface elevation and verified with current data observed by bottom mounted AWAC near the coastal waters of Korea. To validate the operational model we use real-time monitoring data such as hydrodynamic observations by remote Buoy and Tower System, 1 hour averaged surface currents observed by HF-Radar, 1 hour interval surface sediment concentration (SSC) retrieved by Geostationary Ocean Color Imager (GOCI) of the satellite COMS.AO.99jb for the tides, and a eutrophication model CE-QUAL-ICM for the water quality.
