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.
