Along-slope Current Generation by Obliquely Incident Internal Waves

9906941线性工作将使用直接数值模拟来检查倾斜入射的内波从倾斜边界反射、产生沿着斜坡流动的水流并与这些水流相互作用的过程。 这些过程对边界附近混合的产生很重要，因此对海洋的影响远远超出边界附近。 边界混合的细节在现场和实验室中难以观察。 单色和多色入射波场都将被考虑。 要研究的关键问题是随时间变化的行为的强沿坡电流产生的波附近的临界频率和强混合区域的空间分布演变的方式。

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.
