| 基于2005年胶南东部近岸海域的测流资料,分析了该海域的海流、潮流及余流特征,在此基础上,进行了潮流场的数值模拟,展现了M2分潮的潮波系统、潮流椭圆分布、最大流速分布和逐时潮流场。计算结果与实测结果符合良好,较好地反映出该海域M2分潮潮流场时空分布的基本特征。对该海域的水动力状况有了更进一步了解,为胶南近岸海域的环境保护规划的制定提供了科学依据。 |

| Abstract: |
| Based on the observed data obtained in 2005, the feature of the tidal current and residual current in the offshore area of eastern Jiaonan were analyzed. And a numerical model of the tidal current field was also calculated. The figures of tidal waves, the elliptical parameters , distribution of maximum current speed, and current fields at different times for M2 tidal current are obtained. The calculated results agree well with the observed data, which can on one hand reflect the basic specificities of temporal and spatial distribution of the M2 tidal constituent current field to some extent, and on the other hand offer more information about the hydrodynamic force condition. So the paper would provide a scientific basis for making sea environment protection plans in offshore area of Jiaonan in certain conditions. |
