AN ANALYSIS OF THE SPACE-TIME CHARACTERISTICS OF THE SEA SURFACE TEMPERATURE FIELD IN THE NORTH PACIFIC OCEAN

The data used in this study are monthly mean sea temperatures covering the Pacific between 50°N and 10°s during the period 1949-1975.In this paper,empirical orthogonal,correlation and energy spectrum analysis methods were used.We have analysed the seasonal variations,the geographical distributions and interannual variarions of the sea surface temperature and some relationships among the currents in the North Pacific Ocean.The charcteristics of the sea temperature anomalies in the North Pacific are shown as follows:the large horizontal extent;the large vertical depth,the strong anomalous magnitude and the significant longterm oscillation.Finally,the possible effects of the sea temperature anomalies on the general circulation,and the relationship between the sea surface temperature and the North Pacific Subtropical High have also been discussed.
