摘要
分析了2004年东海及黄海部分海域表层水温的分布状况,结果表明,不同水团具有不同的温度年变化,大陆水系的均极差远大于多年平均值,说明沿岸海域的表层水温该年变化比常年大,但黑潮主干区的均极差却比多年平均值低;夏季沿岸海域以及中间水域出现了异常的高温现象,在8月,浙江沿岸、江苏沿岸、长江口以及福建部分沿岸海域的表层水温都突破了近20年的历史最高纪录;在春末、秋末沿岸海域表层水温远高于多年平均值。在暖流区域,除冬季的表层水温高于常年外,其它时间与多年平均差不多,所以年变化相对较小。
The structure and abnormity of sea surface temperature in the East China Sea in 2004 is briefly reviewed.It is concluded that the variations differed for water masses.The inshore waters experienced larger differences in temperature and indicated that the temperatures in these waters changed dramatically.And the difference in the axis of the Kuroshio was lower than its average level of the recent 20 years.In summer,the SST in inshore waters and some of offshore waters appeared very high,and in Aug.the SST in most of inshore areas obtained their highest records in the recent 20 years.Therefore in the ends of the spring and the autumn,the SST in most inshore areas appeared higher than the averages of recent 20 years.For the areas of the Warm Currents,the SST appeared higher than averages of the recent 20 years in winter and showed little deviates from averages in other times of the year,so the changes of year round were smaller than that of averages.
