Conversion of Rossby wave and Kelvin wave

 into each other in the rotating shallow water system

Satoshi Sakai  (Graduate School of Human and Environmental Studies, Kyoto Univ.)

It is shown that Rosby wave and Kelvin wave can be converted into each other at a boundary in a rotating shallow water system using numerical experiments. This conversion makes it possible that Rossby wave  pass through an island in the transient process of an initial value problem. In the steady state, it makes difference on flow resistance between two basin  connected by a channel according to its latitude. This property of the waves can affect the 3-D circulation such as the thermohaline circulation of the ocean not only 2-D flow.
