Laboratory and Numerical Modeling of Topographic Effects on Time Dependent Ocean Currents

当强大的洋流与海底地形相互作用时，在背风面就会形成漩涡。这一提议是研究涡流的产生和衰减过程的稳定和非稳定流动通过地形特征。PI （Boyer）将通过移动相对于分层旋转流体的地形障碍物来模拟旋转槽实验中地形相互作用的影响。此外，将运行一个数值模型（荷兰），使用垂直方向上有20层的原始方程公式。实验室和计算机模型的结果将用于预测海洋中相互作用的地球物理结果。

When a strong ocean current interacts with ocean bottom topography, eddies are formed on the lee side. This proposal is to study the process of eddy generation and decay by both steady and unsteady flows past topographic features. The PI (Boyer) will simulate the effect of topographic interaction in rotating tank experiments by moving the topographic obstacles relative to a stratified, rotating fluid. Additionally, a numerical model will be run (Holland) using a primitive equation formulation with 20 layers in the vertical. Results of the laboratory and computer models will be used to predict the geophysical result of the interactions in the ocean.
