摘要
本文主要根据1984年2月—1988年9月在南起21°49′N,北至27°00′N的台湾海峡及其邻近海域投放“人工水母”的结果,并结合实测底层流资料,对台湾海峡底层流的基本特征进行了分析。发现:台湾海峡区的底层流一年四季都向东北方向流动;在海峡西侧的福建沿岸一带,存在着底层流的向岸流动现象;海峡东侧,底层流主要顺台湾沿岸向东北方向流动;台湾海峡的底层流在北上进入东海后,其主体仍继续沿东北方向流动,在27°00′N,122°00′E附近与来自台湾东北侧的黑潮水(黑潮次表层水)相汇,并继续北上。
A great number of 'sea-bed drifter' were released from Feb. 1984 to July, 1988 into the Taiwan Strait and the sea area north of Taiwan (21°49'-27°00'N, 117°45'-122°00'E). According to the drifting results of the 'sea-bed drifter' and the Taiwan Strait bottom current data observed, the basic characteristics of the Taiwan Strait bottom current are analyzed.1) The directions of the Taiwan Strait bottom current are mainly northward during the year; the speeds of the bottom current in spring and summer are faster than that in autumn and winter.2) Along the coast of Fujian Province, the bottom current flows towards the shore; at the east side of the Taiwan Strait, the bottom current mainly flows northeastwards along the coast of Taiwan, but it is not clear that the bottom current flows towards sea shore there.3) After entering East China Sea, the Taiwan Strait bottom current still flows towards northeast. Near the area (27°00'N, 122°00'E), it converges with the Kuroshio Subsurface Water coming from the northeast side of Taiwan, then flows northwards.
