| Abstract: | Based on the Princeton Ocean Model (POM), Levitus 94 datasets and weekly average of Sea Surface Temperature (SST) and wind data from NOAA satellites, a three dimensional hydrodynamic model, which took into consideration of the M2 tide, was built and applied to simulate the annual cycle of temperature and circulation in the Yellow Sea and to reproduce the process of the Cool Water Mass in the Yellow Sea (CWMYS). The results show that the uniform pattern and stratification pattern are from January to March and from May to November, respectively. The local thermo structure is affected by the CWMYS and the Warm Current in the Yellow Sea (WCYS). The circulation is closely related to the wind field in the Yellow Sea. In winter, the WCYS consists of two branches, the one in the west being its main current. In summer, the circulation is very weak, especially in the center of the Yellow Sea. This weak current region, entrenched at the bottom until November, is an important factor of the CWMYS. |
