台湾海峡海流的季节性变化是明显的。一般说,这里的海流主要由三种不同的流系组成,如图1所示。夏季西南季风盛行,南海季风流在季风的帮助下流向东北,与通过台湾南端的黑潮支流汇合,经台湾海峡后,在东海与黑潮主干相会。在台湾海峡南部地区黑潮海况的变化对闽南——台湾浅滩的海况以及闽南渔场的影响是很重要的。由于这个缘故,人们对这个地区的海洋观测极为重视,其中主要的是沿着22°40′N的断面 Seasonal changes in the Taiwan Strait current are obvious. In general, the ocean currents here consist mainly of three different streams, as shown in Figure 1. The prevalence of the southwest monsoon in summer, the monsoon flow in the South China Sea to the northeast with the help of the monsoon, convergence with the Kuroshio tributary passing through the southern tip of Taiwan and the main Kuroshio in the East China Sea by the Taiwan Strait. The change of the Kuroshio Sea condition in the southern Taiwan Strait is of great importance to the sea conditions of the Minnan-Taiwan Shoal and the impact of the Taiwanese fishery. For this reason, great emphasis has been placed on ocean observation in this area, chiefly along the 22 ° 40’N section
