本文根据1975—1984年东海断面调查资料,分析了北纬28°—32°,东经127°以西海域的温跃层类型、分布、变化特征及其成因。指出了济州岛以南海区温跃层强度最大,浙江近海次之,跃层持续时间最长的是奄美大岛以西。而逆温跃层则以浙江近海最为明显,它的位置与沿岸锋的位置颇吻合。济州岛以南海域温跃层有东西两个强中心,且具西强东弱的特点。
Based on the survey data of the East China Sea from 1975 to 1984, the paper analyzes the types, distribution and variation of the thermocline and their origin in the sea areas of 28 ° -32 ° north latitude and 127 ° east longitude. It is pointed out that the thermocline in the south of Jeju Island has the strongest intensity and the second is in the offshore of Zhejiang Province. The longest duration of the thermocline is west of Amami Oshima. The inversion thermocline Zhejiang Zhejiang Province is the most obvious, its location and quite consistent with the location of coastal front. There are two strong centers of east and west in the thermocline in the sea area to the south of Jeju Island and are characterized by strong east and weak east.
