自Trösch(第四届国际应用数值模拟会议论文集,台湾台南,1984(主编)夏海明、周永利、王善元、谢俊杰)科学与技术丛书,第63卷,1986年,第307-311页。(美国宇航学会)在计算卢加诺湖的低频变率时发现了诱捕的亚惯性振荡,诱捕模型通常考虑平行于海岸线的等间距等深线,在任何陆架-海洋边界上都有近似的边界条件。在这里,对缓慢变化的地形的渐近分析和精确的谱计算演示了在非直线陆架上的陷阱。结果表明,等深线曲率、离海岸和陆架断裂的距离以及陆架断裂时的坡度这三个因素中的任何一个的变化本身就足以产生圈闭。考虑了平稳地与开阔海洋毗邻的大陆架,从而避免了陆架-海洋边界条件的近似,并允许评估以前的近似的准确性。
Since Trösch (Proceedings of the 4th International Conference on Applied Numerical Modeling, Tainan, Taiwan, 1984 (ed. H. M. Hsia, Y. L. Chou, S. Y. Wang & S. J. Hsieh) Science and Technology Series, vol. 63, 1986, pp. 307–311. American Astronautical Society) found trapped sub-inertial oscillations in computations of low-frequency variability in the Lake of Lugano, models of trapping have generally considered evenly spaced isobaths parallel to shorelines with approximate boundary conditions at any shelf–ocean boundary. Here an asymptotic analysis for slowly varying topography and accurate spectral computations demonstrate trapping on non-rectilinear shelves. It is shown that changes in any of three factors, isobath curvature, distance from the coast and the shelf-break, and the slope at the shelf-break, are sufficient on their own to give trapping. Continental shelves that abut smoothly onto the open ocean are considered thus avoiding the shelf–ocean boundary condition approximation and allowing the accuracy of previous approximations to be assessed.
