LAPLACE'S TIDAL EQUATIONS REVISITED

Laplace's tidal equations (LTE) and their consequences, including Kelvin's planar model and Rossby's beta-plane model, are reviewed. Both surface waves and internal waves are considered and are shown to be independent in Laplace's approximation. The limit process implicit in LTE, after their extension to allow for vertical structure, is discussed. It is shown that the Coriolis acceleration associated with the horizontal component of the planetary rotation which is neglected in LTE, induces a coupling between surface and internal waves with periods longer than twelve bours.
