| Abstract: | Abstract In this unsteady barotropic model of the circulation over an oceanic continental shelf and shelf break, account is taken of variations in the surface wind stress along the coast. It is found that the position of maximum onshore flow is very sensitive to the alongshore variation of the wind stress, and that the longshore current becomes more influenced by the shelf break as the wind stress decreases. The relation between the shelf break secondary upwelling and the surface wind stress is investigated. The secondary upwelling is greatest when the wind is increasing most rapidly. |
