Abstract

Oceanic fronts are water regions having different characteristics comparing with their surrounding waters. This tangible difference in temperature, salinity, nutrients, planktons and other physical features can be observable as well as measureable. In this research, in order to study the seasonal changing trends of physical parameters of sea water in the Ras Al Hadd front, the ROMS numerical model was rendered. In fronts, high speeds and changing these speeds are inevitable. Although fronts are usually observed like narrow strips, a wide range of turbulence happens in them. These turbulences are one of the main biological factors for aquatic animals and plants. The intensity of these fronts can have an enormous effect on navigation and shipping. In this zone, this front operates as a seasonal ridge between Oman Sea and Arabian Sea. Oman Sea is a water path between Persian Gulf and free waters (Indian Ocean). Therefore, knowing the patterns of these currents in exporting via water specially oil can be of paramount importance. The preliminary results revealed that the Indian Ocean seasonal currents and winds (Manson), dependent on special atmospheric conditions, mostly happens in the Northern parts of Indian Ocean. This causes some climatic changes in Arabian and Oman Sea that produce two quite different phases. The first is seasonal summer winds or west-south seasonal currents and the second seasonal winter winds or north-east seasonal currents. In the former, a strong northern current in Arabian Sea is apparent. This current, in eastmost parts on Oman, i.e., Ras Al Hadd changes direction into Arabian Sea and makes Ras Al Hadd Front.
