Abstract: The monthly SST data set from the National Climate Data Centre (U.S.A) during 1946-1978 is utilized in this paper.In E1-Nino years,SST of the West said East Australian current and the Mexico current areas decreased, while those increased in other regions. But in cold water years all the results are opposite to the above-mentioned. The results show that one of the maior causes of the South Oscillation and the North Atlantic Oscillation is caused by the SST(from the SE Pacific Ocean to the SE Indian Ocean and in the North Atlantic Ocean) change in latitude seesaw.
