Abstract
A series of numerical experiments were performed to examine the processes influencing dynamics and associated circulation in the Yellow Sea. Model results are compared with measurements data. Coastal tidal station data(surface elevations and residual currents) in Korea and China was used for verification. A study designed to test the sensitivity of each model to various initial stratification, surface forcing and their interactions. An objective criterion for assessing the skill of a model simulation relative to a control simulation is outlined, providing an objective means for identifying which model is better for ocean forecasting system. The model-data comparison shows the numerical abilities and characteristic factor of each model. Three Different type of numerical three-dimensional ocean circulation models are applied to the determination of the various processes influencing circulation in the Yellow-East China Sea. Applied models are COHERENS(A Coupled Hydrodynamical-Ecological Model for Regional and Shelf Seas), DMI-BSHcmod(Danish Meteorological Institute Operational 3D ocean model) and ECOMSED. DMI-BSHcmod model has been running operationally at BSH since mid-90s and at DMI since 2001 in Baltic-North Sea and NE Atlantic. Each model consists of momentum, continuity, temperature, salinity and density equations. All numerical models were simulated as same domain, horizontal grid resolution of approximately 5’ by 5’and all same input forcing conditions. The result shows a reasonable qualitative agreement with observations of the 3D stratification. But a little small distribution of stratified tidal rectified flow to the interior coast was shown. Improvement of simulation for shallow coastal area and intertidal zone would be performed by fine-mesh nesting model. Model result shows a reasonable agreement for hindcast analysis. But this model study should be developed much more for ocean forecasting system.
