Abstract

A numerical model is used to demonstrate wave trapping of the diurnal tides on Porcupine Bank and Rockall Bank. These waves have wave lengths of about 300 km and travel along the sloping topography with shallow water on their right. On the slopes of Porcupine Bank the shorter period K1 wave has a longer wavelength than the O1 wave and so here the trapped diurnal spring-neap signal propagates in a direction which is opposite to the phase velocity.
