| 摘 要： | 利用二维全流水动力方程组，在考虑了海面风应力，潮余流和一开边界入流等条件下，首次模拟出了石了石岛附近的中尺度反旋式涡旋海水运动，并对南黄海西部冬季环流的特征作了初步探讨。数值模拟结果和实测吻合良好，数值模拟表明：冬季南黄海西部环流形式主要决定因子是海面风应力、潮余流及从开边界的流入该海域的黄海暖流及黄海沿岸流。黄海暖流在偏北风作用下沿西北方向可直达山东半岛近岸，后分为两支：一支向南汇入黄海沿岸流流

| Abstract: | Current measurement and traces of drift bottles and drift cards show existence of a mesoscale anticyclonic eddy in the Qingdao Shidao Offshore round the year. A two dimensional barotropic numerical model is first employed to modelling this eddy phenominon. It is shown that in winter, the northwestward Yellow Sea Warm Current (YSWC) forced by winter mosoon can reach to Qingdao Offshore and then diverged into two branchs. The left one joins with the Yellow Sea Coastal Current (YSCC) along main land coast. The right one flows northeastward and forms the anticyclonic eddy with YSCC from northen Yellow Sea. The computational results agree well with observations. |
