Wind Pulse Effect on Coastal Current

Abstract

Shallow water equations have been used to analyze the final stage of the response of a semi-infinite rotating basin to the wind impulse effect simulating the passage of a storm in the presence of a coastal current. It has been shown that the most significant effect upon a high storm intensity is that the coastal stream core shifts several kilometers toward the coast or from the coast, depending on the sign of the Ekman transport. The additional currents arising after the storm passage in the presence of an alongshore stream differ only quantitatively from the currents arising in its absence.
