Abstract

An unsteady stratified model of the Skagerrak is described. The model includes the trench along the Norwegian coast and the shelf on the Danish side and is driven by a combination of surface wind stress, outflow from the Kattegat and run-off from the rivers and fjords along the Norwegian coast. The seasonal variation of the run-off is described and incorporated into the numerical model. Certain wind and run-off conditions produce a general outflow in the trench. Other conditions induce an outflow by the coast with a counter-current in the centre of the trench. Recirculation often occurs near the Swedish coast.
