夏季台湾海峡南部海区的海流结构

本文根据台湾海峡南部海区夏季的海流调查资料,参考温、盐、密度等的历史资料和有关方面的研究成果,论述了表层、中层和下层的海流结构。结果表明,南海暖流继续沿着海区中部向东北延伸,但在粤东、闽南近岸的表层这支海流还受到沿岸低盐海水的影响;而黑潮南海分支北段的边缘部分可以影响到本海区的南部海域,这一部分还可能有一支流分出并沿着台湾岛西岸北上。

THE CURRENT STRUCTURE DURING SUMMER IN SOUTHERN TAIWAN STRAIT

Based on measured current data and the distributions of temperature, salinity and density, the summertime current structure of the surface layer, intermediate layer and lower layer in Southern Taiwan Strait (STS) has been described. The South China Sea Warm Current extends to the northeast along the central part of the STS, but might be affected by low salinity sea water in the surface of the nearshore area. The northern section of the South China Sea Branch of Kuroshio might influence the seuthern area of the STS and then separate into two branches, of which one goes along the western coast of Taiwan Island.
