Abstract
This study investigates the role of mesoscale eddies significance in marine and climatic environmental researches. Therefore, mesoscale eddies in the Persian Gulf (PG) were identified and tracked based on the SSH-based method using the Arc GIS software. The Sea Surface Height (SSH) field data were extracted from the AVISO Reference Series from 2010 to 2014. The areas with the highest activity of eddies are located in the northern and central regions of the PG. The strongest eddies are observed in summer. Therefore, major environmental impacts of eddies were observed in the north of the PG in parallel with the Iranian coasts. Considering the Eddy Kinetic Energy (EKE) and the eddy diffusion coefficient, cyclonic eddies had more climatic and environmental effects, and the tracers such as pollutants can be dispersed quite rapidly in the north of the PG along the Iranian coast. Eddies (cyclonic) also appear to have the effect of cooling and .decreasing temperature typically by 1 °Celsius in the atmosphere of the nearby regions.
