| 摘要: |
| 在我国,关于黄海、东海温、盐度逆转结构的分析研究,主要是在80年代以后开始的。翁学传等(1984)、曹欣中等(1982)和丁宗信(1983)对东海某一特定海域的温、盐度逆转结构进行过分析,但是对整个黄海、东海海区来说,有关这方面的研究尚未见报道。
本文根据1983-1986年中国科学院海洋研究所在黄海、东海每年夏季调查的CTD观测资料,同时参考1963年以来国家海洋局调查的标准断面资料,对黄海、东海夏季(6-8月)温、盐度逆转結构的分布及其成因进行初步的分析研究。
根据资料和兰淑芳等(1985)的分析,北黄海很少出现温、盐度逆转结构的类型,虽偶有出现,但分布也不规律,因此本文把研究海区重点放在南黄海和东海(图1)。 |

| Abstract: |
| Based on temperature and salinity data gathered from 1963 through 1986 in the Yellow Sea and the East China Sea in summer, the distributional characteristics of the inverse structure of the temperature and salinity and its formative causes are analysed in this paper. Some results show that (1) the inverse structure in summer can be found in three regions, the area of the Zhejiang Coast upwelling, the area of the cold eddy in the northern part of the East China Sea and the area of cold water mass in the southern Yellow Sea, (2) the inverse structure in above three areas can be separately caused by the wind, the vertical circulation in the area of the cold eddy,and the northward extension of the Huanghai warm current water which is warmer and more saline in bottom. |
