Abstract:

A new two-layer model consisting of generalized Boussinesq equations is derived which contains forcing terms due to barotropic tidal flow over large-amplitude bottom topography. These equations can describe both the generation of nonlinear dispersive internal tides and their disintegration into solitary waves. Special attention is paid to the effects of Coriolis dispersion (which is due to the earth's rotation). Numerical solutions based on observed oceanic conditions show convincingly that the earth's rotation can be a decisive factor at mid-latitudes in that it tends to impede the disintegration of the internal tide. Oceanic observations in the Celtic Sea and in Massachusetts Bay are well reproduced by the model.

More about this publication?
  • The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
