本文根据1980年7月至1981年6月在彭佳屿与基隆之间两个浮标站的测流资料,并结合东海南部的有关水文资料,分析了夏季东海海水流动的若干主要问题,认为东海南部陆架区的下层海水具有黑潮次表层水的特性,它是从台湾东北方基隆—彭佳屿—东经122°30′,北纬25°40′一带进入陆架海区的,而上层水则主要来自台湾海峡。此外,本文还讨论了台湾岛的绕流作用以及台湾岛东北方气旋式涡旋和本区中部反气旋式涡旋的形成原因。
Based on the measured data of two buoy stations between Pengjiayu and Keelung from July 1980 to June 1981, and combined with the hydrological data in the southern part of the East China Sea, this paper analyzes some main problems of the flow of sea water in the East China Sea in summer. The lower shelf seawater in the southern shelf area has the characteristics of Kuroshio subsurface water. It enters the shelf area from Keelung-Pengyu-Dong longitude 122 ° 30’E and latitude 25 ° 40’N in the northeast of Taiwan, while the upper water mainly comes from Taiwan Strait. In addition, this paper also discusses the flow around the island of Taiwan and the northeastern Taiwan island cyclone vortex and the central region of the formation of anti-cyclonic vortex.
