摘要: 根据1996年10月中韩合作调查获得的CTD资料,分析探讨了南黄海秋季跃层的分布特征及垂直混合状况,同时对黄海冷水团的垂向混合进行了初步探讨.还利用改进后的逐步聚类分析法划分了表、底层水团,确定了各水团的温度、盐度、溶解氧和PH值4要素的平均特征值,并根据各水团的特性和温度、盐度的平面分布特征,重点探讨了黄海水与沿岸水及东海水的混合和交换.Abstract: Based on the CTD data obtained from China-Korea Joint Investigation in October 1996,the characteristics of thermocline and vertical mixture in the southern Huanghai Sea in autumn are analysed,and the vertical mixture in the Huanghai Sea Cold Water Mass area is preliminarily discussed,The cluster analysis and Bayes multistage discrimination methods are used to classify the surface and bottom water masses and define the average characteristic values of temperature,salinity,dissolved oxygen and pH for different water masses,The discussions are focused on the mixture and exchange of the Huanghai Sea water with the coastal water and the East China Sea water according to the distributions of temperature and salinity,and the characteristics of different water masses.
