Along-slope Current Generation by Obliquely Incident Internal Waves

9906941 Slinn这项工作将使用直接的数值模拟来研究倾斜入射的内波从倾斜的边界反射，产生沿斜坡流动的电流，并与这些电流相互作用的过程。这些过程在边界附近混合的生产中很重要，因此对延伸到边界附近以外的海洋产生影响。边界混合的细节很难在野外和实验室中观察到。单色和多色入射波场都将被考虑。需要研究的关键问题是波在临界频率附近产生的强沿坡流的时间相关行为，以及强混合区的空间分布演变方式。

9906941SlinnThis work will use direct numerical simulation to examine the processes by which obliquely incident internal waves reflect from a sloping boundary, generate currents flowing along the slope, and interact with these currents. These processes are important in the production of mixing near boundaries and hence have an effect on the ocean that extends far beyond the immediate vicinity of the boundary. The details of boundary mixing are difficult to observe in the field and in the lab. Both monochromatic and polychromatic incident wave fields will be considered. Key questions to be investigated are the time-dependent behavior of the strong along-slope currents generated by waves near the critical frequency and the way in which the spatial distribution of regions of strong mixing evolves.
