基于海洋资源开发、环境保护和近岸海域地貌复杂性等原因,浅海余环流的研究引起了世界各国海洋学者的兴趣。余环流是风海流、热盐环流和潮余流耦合形成的。滤掉实测流的周期性部分,剩余的环流就是这三部分海水运动的合成结果。余环流难以分解成上述三个组成部分。因而在讨论浅海余环流的场合下,我们应将这三个分量当做一个统一的整体现象予以考虑。根据这个论点,冯士筰、奚盘根和本文第二作者提出了浅海斜压余环流模型。本文将这个模型应用于中国渤海并采用有限元方法求解了模型方程。计算结果与实测资料符合良好。
Based on such reasons as the development of marine resources, environmental protection and the geomorphological complexity of coastal areas, the research on the shallow circulation over the sea has aroused the interest of oceanographers all over the world. The residual circulation is formed by a combination of wind currents, hot salt circulation and tidal residual flow. Filter out the periodic part of the measured flow, the remaining circulation is the result of the synthesis of these three parts of seawater. Remaining circulation difficult to decompose into the above three components. Therefore, in the discussion of shallow sea circulation, we should consider these three components as a unified whole phenomenon. Based on this argument, Feng Shizhen, Xi Pangen and the second author of this paper put forward a shallow sea baroclinic residual circulation model. This paper applies this model to Bohai Sea, China and solves the model equations by finite element method. The calculated results are in good agreement with the measured data.
