The aim of this study is to analyze the vertical profile of temperature for studying the double diffusive convection using a three-dimensional numerical model in the east of Persian Gulf. Vertical profile of temperature is the precise and explicit description of temperature in various layer of ocean with considering the seasonal variation. The Persian Gulf, particularly in the Strait of Hormuz area is one of the most important region in terms of marine environmental, ocean sciences, economics, commercial and military, therefore description of seasonal cycle of temperature is important in this region. Temperature profile has an important role in physical oceanography, marine chemistry and biology. In this study vertical profile of temperature and its spatial distribution in various layer of Persian Gulf were analyze using a 3-D numerical model (COHERENS) during the year. For reaching the steady state of Physical feature such as temperature and salinity, the model was run for five year in Persian Gulf. The results of model were comparing with field observations of Jones and Zentop that get from Strait of Hormuz, which are agreement with our results and show that in the spring and summer there is a strong thermal difference between surface and deep layers, so that in some parts, it reaches 12. As already mentioned this severe difference, causes to strong stratification of density and then leads to static stability of currents in upper layer. In autumn by decreasing the surface layer temperature, the heat transfer from deep layers to the surface occurred because of convective currents that leads to significant decrease the temperature of deep layer and also decrease of sharp contrast of summer temperature between surface and bottom that cause to predict of convection in the Strait of Hormuz.
