Temperature Variations Modeling in the Persian Gulf Using the Numerical Model of POM

Temperature, Salinity and density are as some of physical properties of sea water often varying there. Thermocline is a property as temperature varying in water column and having variations in terms of time and space. Study and investigation of existence and developing trend with seasonal variations conduct the researcher to some information about inter fluid events. Numerical methods have errors and approximations. Predicted values will be closer to real ones depending on more knowledge about influence of present forces and effective factors on the problem; so little errors happen in numerical study. Of course it is helpful to predict results for different time periods in suitable time and so compete them with measured values for evaluation of the results in the case study zone. In this research running a numerical model during a 6 months period from winter using measured values of temperature (ROPME 1992), and applying initial and boundary conditions, also effective factors on physical conditions variations in the zone, summer temperatures are resulted; Therefore formation and development of thermocline will be studied. In fact, development of thermocline from Strait of Hormuz to northwest of the Persian Gulf (Arvand river estuary) has been investigated by numerical modeling of temperature variations as dominant parameter.
