چکیده:

Abstract: Initially an over view of some examples and importance of Geophysical Fluid Dynamics are explained. Then, results of some observational data and numerical simulation are used to consider the dynamics of the Persian Gulf outflow during two different time of the year, mid-winter and early summer. The numerical results include the either the Strait of Hormuz or the whole of the Persian Gulf and the Oman Sea. The results for the Strait of Hormuz region reveal that during the winter the outflow boundary current detaches from the coast well before the Ras Al Hamra Cape, however for the summer the outflow seems to follow the coast even after this Cape at shallower depth. This is due to higher density of the outflow due to lower temperature that leads to more sinking of the outflow during the winter. Thus, it moves to deeper parts at about 300-400 m in contrast with that of summer which is at about 200-300 m. During winter, the deeper, stronger and wider outflow is more affected by the steep topography, leading to separation from the coast. While during summer weaker and shallower outflow, is less influenced by the bottom topography and seems to disappear downstream of the Ras Al Hamra Cape. The numerical results for the whole region which includes a more realistic forcing for the outflow, show less deepening of the outflow in winter as it inters the Oman Sea in winter, indicating that forcing boundary condition in the Persian Gulf is important on its spreading pathways.
