In this study, the new version of COHERENS model is evaluated with Appling the most accurate bathymetry data and forces with high temporal resolution and spatial resolution in the Persian Gulf. The results correspond well to observations and previous modeling studies. According to the results obtained in this research, a cyclonic gyre forms in the central Gulf from April to July. During August, the baroclinic instability creates the most activity mesoscale eddies along the salinity front. The remnants of eddies are seen until September, after which they dissipate as wind intensifies and stratification decreases due to winter cooling.The surface salinity results show that a fresh plume heads from the Arvandrood towards the Saudi coast in winter and towards the Iranian coast in summer. The saltiest hence densest water masses of the Persian Gulf are formed in winter in the northwest and in the southern banks, but the latter reaches the Strait of Hormuz from November to April only.
