自1913年以来,福冈县水产试验站一直在对马海峡东部的固定断面上进行海洋观测.根据1919年到1979年的观测资料,研究了水温的季节变化和长期变化。平均水温偏差夏季大,特别是在50米处的温跃居。异常高温出现在春季到秋季。反之,异常低温出现在秋季到春季。对马海峡东部的水温长期变化表明从1919年到1943年是6年或8年周期,1948年以后是6年周期。 Fukuoka Prefecture Aquatic Experimental Station has been conducting ocean observations on a fixed section of eastern Strait of Matsushima since 1913. Based on the observations from 1919 to 1979, the seasonal and long-term changes in water temperature were studied. The average water temperature deviates from summer, especially at 50 meters. Abnormal high temperature occurs in the spring to autumn. Conversely, abnormal hypothermia occurs in the fall to spring. The long-term changes in the water temperature to the east of the Strait of Morse indicate a period of six years or eight years from 1919 to 1943 and a six-year period after 1948.
