【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。更多还原

【Abstract】 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.更多还原
