The main feature of the Arabian Sea is the monsoon reversing winds during the summer and winter monsoon. The seasonal variations of hydrophysical parameters of Arabian Sea surface are strongly influenced by seasonal monsoon winds. In this study, the distribution of sea surface temperature (SST), sea surface salinity (SSS) and the mixed layer depth (MLD in the region between 56E-73.4E and 18N-25N are investigated using MITgcm model with a spatial resolution of 2 arc-minutes during Monsoon. Temperature, salinity, wind, net heat flux and evaporation minus precipitation rate are applied to the model as initial data. The model has been steady after 20 years. The results of modeling show that the average SST during the summer monsoon is 2.1ºC more than the winter monsoon. The model predicted the summer cooling of Arabian Sea well, so that in the southwestern region and during the winter monsoon SST is about 0.5°C more than the summer monsoon. On the other hand, the difference SSS between two monsoons is about 0.1PSU. The MLD is deeper during the winter monsoon than summer monsoon. The shallowest MLDs occur during the summer monsoon and on the southern coasts of Iran specially in the coast of Chabahar, while during the Winter Monsoon, The deepest MLDs are found in the western coast of India and also the shallowest in the coast of Oman.
