| Abstract: | A forecasting and information service system is set up to meet increasing demands for marine environment prediction. The system consists of a high-resolution wind-wave-current coupled numerical forecast model with data assimilation module, which covers the South China Sea and its adjacent sea areas; and a marine dynamic environment database and visualization platform. The forecast model uses the C-Coupler to couple the WRF (Weather Research Forecast) mesoscale numerical weather prediction system, the wave numerical model MASNUM (Marine Science and Numerical Modeling) and the regional ocean numerical model ROMS (Regional Ocean Modeling System). In order to generate precise initial conditions for the wind-wave-current prediction, the forecast system also conducts a 12-hour hindcast simulation using the ensemble adjustment Kalman filter (EAKF) data assimilation method before prediction. The forecasting outputs are collected by the marine dynamic environment database and displayed by the visualization platform to provide 72-hour forecasting products of marine environment in the South China Sea and its adjacent sea areas. |
