Abstract
The aim of this study was to identify the degree of dynamic induction regarding the dependence of water temperature on the Persian Gulf over a period of 36 years with surface temperature in the southern hemisphere regarding air, oceans, and land-ocean. After the time series of data, the comparison between the surface temperature on land, sea, average land-sea in the southern hemisphere, and the surface temperature of the Persian Gulf in different time intervals with time approaches in the two sections of annual observation and matched months done. The maximum significant linear relationship between air temperature anomalies in the Southern Hemisphere and the Persian Gulf at the same time (different seasons) is related to the period 2000 to 2005 and the minimum is related to 1993 to 2017, on the other hand, the years 1994 to 1999 and 2012 to 2017 the correlations are similar. The amount of linear correlation between the mean anomaly of air temperature in the southern hemisphere and the surface temperature of the Persian Gulf in the same months shows that in the whole range of 14%, the relationship is significant, of which 30% is inverse. Therefore, the complete relationship between these two quantities is not observed in the period of thirty-six years and 85% of the relationship is completely meaningless. Calculations show that linear multivariate regression does not have significant values either stepwise or simultaneously.
