Abstarct A numerical simulation of using the ROMS (Regional Ocean Model System; http://marine.rutgers.edu) was conducted for seasonal circulation and thermohaline structure in the Yellow Sea. This study demonstrates the applicability of the terrain-following ROMS model to major processes in the Yellow Sea such as distinct features of different circulation patterns, dilution of seawater due to fresh water discharge from major rivers, exchange between coastal waters and shelf waters across the tidal fronts etc. The model adopts curvilinear grid with horizontal resolution of 3 5 km and 20 vertical grid spacing confirming to relatively realistic bottom topography. The model was initialized with the LEVITUS annual climatological data and forced by the monthly mean air-sea fluxes of momentum, heat and fresh water derived from COADS. On the open boundaries, climatological temperature and salinity are nudged every 5 days for data assimilation. This study demonstrates a Yellow Sea version of Atlantic Basin experiment conducted by Haidvogel et al. (1999) experiment that the ROMS simulates the dynamic variability of temperature, salinity, and velocity fields in the ocean.
