摘要
根据海洋调查历史资料,对我国台湾东北海域的冷涡基本状况——季节变化、类型、结构与特点进行探讨,主要结果如下:(1)首次提出该海域的冷涡有三处;在春季和夏季,有时出现双涡并存现象。(2)首次划分该海域的冷涡有二类6型。(3)该海域的冷涡移动与黑潮流轴摆动有关,并认为那里的冷涡—上升流,是黑潮对我国近海海洋环境影响的典型实例之一。(4)该海域的冷涡具有低温、高盐、高密、低氧、高磷、高硅、高氮等特性。
Based on the historical marine observational data, the basic conditions of the cold eddy in the sea area northeast of Taiwan are analysed, which include the seasonal variations, pattern , structure and other characteristics. The main results are as follows: (1) In this area, the cold eddies appeared in three places, and sometime, dobule eddies exist side by side in spring and summer; (2) The cold eddies in the studied area are classified into two patterns and six typies; ( 3) The movement of the cold eddy is relative to swing of the Kuroshio axis, and it is considered that the cold eddy-upwelling is one of the typical examples of the influences of the Kuroshio on the off shore environment of China;and (4)The cold eddies are characterized by lowtemperature, high salinity, high density, low oxygen, high phosphorus, high silicate and high nitrogen.
