Abstract
The aim of this research is studying the possibility of upwelling occurrence in the Iranian coastal area of Oman Sea. The occurrence of such a unique phenomenon near the coastal area of Jask made it a suitable subject to the study. To achieve this aim ArcGIS and MIKE3 softwares were employed. Year 2016 was considered for this research. Using ArcGIS techniques the patterns of prevailed wind, sea surface temperature, and concentrated chlorophyll-a using satellite remote measurement data for the area under investigation were taken into consideration. These plots confirm the probability of occurrence of upwelling in the area. For the simulation with MKE3, irregular mesh was designated as horizontal grids. In the vertical direction sigma layer stratification with 10 layers were chosen. After calibrating the model, results derived from the simulation were analyzed around Jask headland. The results indicate the existence of an upwelling during transition period of monsoon (October and November). This was simultaneous with the prevailed wind in the southwestern coast of Oman Sea.
