本文根据CTD观测资料,分析了研究海区的温、盐、密度跃层的分布与变化,讨论了逆温逆盐层的分布区域,并从跃层角度出发,分析了深层水的涌升,黄海冷水团的上边界以及台湾暖流在东海北部的影响范围。 Based on the CTD observations, the distribution and variation of temperature, salt and density thermocline in the study area are analyzed. The distribution of inversion temperature inversion salt layer is discussed. From the perspective of thermocline, the rising of deep water, The upper boundary of the cold water mass and the impact of Taiwan’s warm current in the northern part of the East China Sea.
