中文摘要
本研究的重点是与海浪和海流、漩涡的稳定性有关的流体动力学问题。在这种意识下要解决的特殊问题将是水动力稳定性和混沌现象、内部潮汐、潮汐摩擦和模态。早期的一种观点认为,流体在每一种更复杂的模式下都变得不稳定,直到它们在随机意义上变成湍流。流体动力学稳定性的最新发展利用奇异吸引子技术表明,最终状态可以称为“混沌”,即不是随机的,在某种意义上是确定的。这些技术将应用于海洋表面波、潮汐、内潮、合理强迫罗斯比波和准等转孤立波的研究。这些研究解决了对海洋运动整体动力学具有根本重要性的问题,并可能引起海洋学界许多人的兴趣。
英文摘要
This study focuses on work in fluid dynamics problems related to ocean waves and the stability of ocean currents and eddies. Particular problems to be addressed under this aware will be hydrodynamic stability and chaotic phenomena, internal tides, tidal friction, and Modons. An early idea held that fluids become unstable in every more complex modes until they become turbulent in the stochastic sense. Recent developments in hydrodynamic stability use the techniques of strange attractors to show that the final state may termed "choatic", i.e., not stochastic, and in some sense determinestic. These techniques will be applied to the study of surface waves, tides, internal tides, reasonantly forced Rossby waves, and quasigeostrophic solitary waves in the ocean. These studies address problems of fundamental importance to the overall dynamics of ocean motion, and are likely to stir interest among many in the oceanographic community.
