SST EOF identified the front which separates the Persian Gulf cyclonic gyres. The first mode of the SVD analysis seems depict an air-to-sea forcing, in which the sea response to the atmospheric changes appears with an semiannual and interannual time lag. The main patterns of both variables of variability of both variables independently provide considerable information on the coupling, but only one of the two variables dominates each of the two first coupled modes. The first coupled mode of variability between the sea surface temperature and atmospheric
pressure can be described as a strengthening and weakening of the cyclonic gyres, which seems to force fluctuations in a north-south dipole structure in the sea surface temperature by Ekman upwelling which is wind related processes.
