Operational Storm Surge Forecasting in the North China Sea

There are storm surge disasters along the coast from the north to the south in China. In the Bohai Sea and Yellow Sea, the storm surges happening in summer are usually induced by typhoon or tropical cyclone, while by cold air or extra-tropical cyclone in winter time. An operational storm surge forecasting model for the North China Sea has been developed by North China Sea Marine Forecasting Center based on FVCOM. The meteorological forcing data is delivered by the operational forecasting WRF model, in which Bogus scheme is used to improve the numerical description of typhoon process. In the present paper, four cold-air and typhoon storms are simulated with our operational storm surge forecasting model, and the verifications show that our model has a high accuracy and good performance in storm surge forecasting.
