| Abstract: | The main features of a new three-dimensional spectral model for the motion of a stratified sea are described. The model is applied to determine wind-induced elevations and currents over an idealised shelf-edge slope during the summer season of thermal stratification. A wind stress field spanning the slope is applied in the form of a rectangular pulse through time, the direction of the stress being parallel to the shelf edge. It is shown that strong vertical motion occurs near the top of the slope in the wind region; inertial currents are excited. Outside the wind region, long-period waves trapped over the slope and propagating along it may be identified. |
