Theory and Modeling of Internal Wave Generation in Straits
Abstract
The primary objective were on connecting the generation process with the dynamics of the disintegration of the radiated internal tide into shorter, nonlinear internal solitary-like waves and to predict the space and time scales for the emergence of waves and their properties (e.g. wave amplitudes, numbers, etc.). A central aspect of this work is to explore the role of rotation in the process. Rotation permits the presence of periodic, nonlinear inertia-gravity waves (i.e., the tide) that can act as attractors and arrest the steepening of the internal tide, and hence affect the production of the shorter solitary-like waves (Gerkema, 1996; Helfrich and Grimshaw, 2008). A related objective is the long-term effect of rotation on the emerging solitary waves, where it has been shown that these waves may decay to procude nonlinear wave packets (Helfrich, 1997; Grimshaw and Helfrich, 2008).
