SENSITIVITY ANALYSIS OF PBL SCHEMES OF THE WRF-ARW MODEL IN SIMULATING WIND SURFACE OVER PERSIAN GULF

The study of Persian Gulf as one of the largest energy sources in the world and one of the connection paths between marginal countries with the other regions of theworld has a special importance. Wind over sea and ocean is one of the effective factors on economic activities in every region but unfortunately atmospheric observationdata in overseas area is in intense shortage in compare with overland data. In order to maintain the safety of life in overseas and coastal areas and construction of neededoffshore and onshore structures there must be enough knowledge about the wind variability and the waves caused by wind[1]. On the other hand the most commoneffects of wind on ocean is seen in wind driven currents, swells and oceanic circulations (upwelling and down welling)[2]. Also wind has an key role in the modeling ofphenomenon caused by the interaction between atmosphere and ocean (e.g. Drag coefficient)[3]. In other words uncertainty in the determination of surface windcould cause a large difference in the output of atmospheric and oceanic models.
