2006年东海及部分黄海海域表面水温状况分析

分析了2006年东海及部分黄海海域的表面温度状况。研究表明,不同的水团具有不同的温度年变化特点,大陆水系的均极差远大于多年平均水平,说明沿岸海域的表面温度年变化比常年更大,同时黑潮主干区的均极差也比多年平均值高,所以,无论是沿岸海域还是暖流区,2006年的表面温度变化都比常年剧烈。暖流中黑潮暖流、对马暖流以及黄海暖流总体状况与多年平均差不多;而台湾暖流则在2006年大部分时间中保持比多年平均略高的状态。沿岸海域中偏南的区域水温高于多年平均,偏北的区域则与常年差不多,特别是福建沿岸、浙江沿岸和长江口及邻近区域在春季出现了温度偏高的状况。此外,值得注意的是2006年秋季黄、东海区大部分海域的表面温度呈现比多年平均略偏高的状态。

Analysis on the status of surface temperature structure of the East China Sea and partial Yellow Sea in 2006

The structure and abnormality on the surface temperature of the East China Sea and partial Yellow Sea were analysed in 2006. The results showed that the variations differed for the different water masses. The offshore water and the axis of the Kuroshio experienced more differences on the surface temperature as compared with its average of the recent years, and revealed that the temperature in these water areas changed dramatically. Meantime for the areas of warm currents such as both Kuroshio and Tsushima current as well as Yellow Sea warm current, most of them, appeared a little differences than the averages, but the Taiwan warm current showed a higher level than the average for most time of the year. In the coast areas, the southern part of the East China Sea such as Fujian and Zhejiang coastal area and Changjiang River Estuary appeared higher than the average in almost whole year, especially in Spring. The others appeared lower in first half and higher in second half as compared with the average. It is noteworthy that there was a remarkable phenomenon in the fall of 2006, the SST in most part of the interrelated area revealed higher than the average.
