| 内容記述 | This paper describes the long-term variations in hydrographic conditions in the Tohoku Area. Temperature variations at 100 m depth (EOF1) measured from a representative area between 1964 to 1993 are analyzed with the northern limit of the Kuroshio Extension axis (NLKE) during the period 1954 to 1993 and the south limit of the First Oyashio Intrusion (SLO1) during the period 1964 to 1993. Variations in EOF1, NLKE and SLO1 have common cyclical periods of approximately three to four years. This period is similar to that of occurrences of El Niño events. Variations in EOF1 and SLO1 also correlated well with each other over longer periods. EOF1 was large (higher temperatures) before 1981 and small (lower temperatures) after 1981 with SLO1 being large (shifted northward) before 1980 and small ( shifted southward) after 1980. However, variations in the NLKE are not always correlated with that of the EOF1 or SLO1 over longer periods. NLKE had maximum values between 1955-1958 and 1978-1980, whereas it had minimum values between 1963-1965 and in 1984. NLKE varied in approximately twenty year cycles. Cross-correlation function analysis showed EOF1 and SLO1 to vary nearly at the same time, and that the temperature, EOF1, was high when SLO1 shifted northward and temperature low then SLO1 moved southward. It was also found that the NLKE varied several months later than EOF1 and that the NLKE and SLO1 were found to be scarcely correlated with each other. | |||||
