东海东北部夏季水文状况的研究

本文主要根据韩国海洋研究所通过东海沿岸海洋过程试验（即COPEX－ECS）收集的CTD资料,较详细地研究了东海东北部夏季的水文状况．文中首先分析了夏季出现在该海域最重要的几件海洋现象．其中主要包括长江冲淡水的东向扩展,黄海底层冷水南向插入,以及黑潮水的爬升和渗透。然后,使用t－S分析法,并参考有关研究成果,对东海东北部夏季水团进行了划分,并重点探讨了黑潮水和对马暖流水的结构特征。最后,本文讨论了朝鲜／对马海峡东、西水道夏季水文结构的差异问题。

The Hydrographic Condition in the Northeastern East China Sea in Summer

Summertime hydrographic condition in the northeastern East China Sea (NE-ECS) are studied mainly on the basis of the CTD data collectted by the Korea ocean Research and Development Institute (KORDI) through a project on " Coastal Ocean Process Experiment-East China Sea (COPEX-ECS)". At first. an intensive analysis is made of some of the most important oceanographic phenomena which occur in the NE-ECS in summer. The phenomena involve mainly the eastward extension of the Changjiang Diluted Water . the southward intrusion of the Huanghai Bottom Cold Water. and the upwelling and the penetration of the Kuroshio into the shelf . And then, the summcrtime types of water mass in the NE-ECS are classified by using the t-S diagram and consolting the relevant studies. The structures of the Kuroshio Water and the Tsushima Warm Current Water are described in more detail. Lastly , we discuss the remarkable differences in the summertime hydrographic structures between the western and eastern channels of the Korea/Tsushima strait.
