| 요약 | This dissertation is an analytical and numerical investigation into the longstanding hypothesis that seamounts are the "stirring rods'' of the ocean. Specifically, it has been proposed that the eddy motions generated by the interaction of underwater mountains with ocean currents might play a significant role in the broader field of ocean mixing. The energy associated with vertical mixing in the ocean is of critical importance for climate models. The effect of seamounts, however, must be parameterized in climate models due to finite computational resources. There remain open questions about the magnitude and mechanisms of seamount-induced mixing, which are not currently accounted for in climate models. To address this, as well as other questions, a series of numerical simulations of an idealized seamount interacting with a uniform flow are carried out. The effects of density stratification and the Coriolis force are included in the simulations, and a range of values are considered. This set of simulations spans a broad range of Froude and Rossby numbers that might be encountered in the ocean, and forms the basis for the analysis conducted in this dissertation.The first component to this thesis is tied to the fluid mechanical aspects of the simulations. The problem of rotating, stratified flow past a 3D obstacle is of fundamental interest |
