【摘要】 系统整理的历史实测海流和温盐资料显示出青岛─石岛近海水域全年都存在着中尺度反气旋式涡旋运动．利用二维数值模式，首次模拟出该涡旋的存在，并对这一涡旋的形成机制进行了探讨，数值模拟结果和实测吻合良好．数值计算表明：在冬季盛行风的作用下，山东半岛南岸出现减水，迫使北上的黄海暖流中的一部分向西北方向延伸，在到达山东半岛近海后向右转向，形成东北向沿岸流，这样，与绕过山东半岛大约沿40～50m等深线南下的黄海沿岸流作用，在青岛─石岛近海形成一个中尺度反气旋涡旋．夏季由于偏南风的作用，致使山东半岛南部近海浅水区域海水都向东北方向流动，与沿黄海冷水团锋面南下的黄海沿岸流相作用，由于流速切变也形成了上述涡旋．更多还原

【Abstract】 Current measurement and traces of drift bottles and drift cards show existence of a mesoscale anticyclonic eddy in theQingdao-Shidao off shore in a round year. A two dimensional numerical model is firstly employed to modelling this eddy phenomenon. In the model we consider the main factor which influences the circulation greatly as wind stress, real topography, volumetransportation, baroclinic effect etc. It is show that an anticylonic eddy which exists in the area near the Qingdao-Shidao coast.The computational results agree well with the analysed results from observation. The distribution of salinity and temperature alsoshows the exlstence of the antlcyclonic eddy. By analyse the Vortex Equation and the result of a series of numerical model tests,the reason why and how this eddy is formed is explained.更多还原
