Simulation of wind-driven circulation in the Gulf of Elat Aqaba/

The Princeton Ocean Model POM. has been used to investigate the wind-driven circulation in the stratified long and narrow Gulf of Elat Aqaba.. Our results indicate that the circulation consists of a series of gyres aligned along the main axis of the basin, and that their size and location are strongly affected by the shoreline and, to a lesser extent, by the hydrography. The seasonality in both the flow and the free surface height FSH. at any specific station are caused mainly by the strong seasonality in the hydrography — the FSH and the magnitude of the currents above the thermocline are inversely related to the thickness of the upper layer. The seasonality in the flow is also manifested in the location and diameter of the gyres. This seasonal change in the gyres’ diameter and location might provide an explanation for the current reversal observed at the northern tip of the western boundary during the month of February.
