چکیده:

Many factors such as wind, tide, density and pressure gradients cause oceanicand marine currents. For the reason that the density of layers are different , thereforethe moredense layer moves in direction of the less dense layer and consequently Quasi -Geotrophic currents are formed. In this study we have considered the northern coasts of the Persian Gulf. Also the governing equations have been solved using the method of finite_difference. The components u and v_have been obtained using the information of 30 stations and calculating the slope between two layers with considering depth and density variations in direction latitude (26° ۲۵′ to 28° ۱۱′) and longitude (49° ۷۱′ to 52° ۳۴′). The results are in relative good agreement with the results of the other mathematical models that have been already obtained for the Persian Gulf. On the basis of this study, for the spring season, the maximum of velocities_is about 0/01(m/s__and the minimum of them is 0/0001 (m/s).
