菲律宾东部沿岸流

A COASTAL CURRENT ALONG THE EAST OF PHILIPPINES

根据1986～1989年间9～10月中国科学院海洋研究所“科学一号”船在菲律宾东部海域获得的CTD调查资料,分析了菲律宾东部沿岸流。分析得出,菲律宾东部沿岸流是一支每年都存在的南向流,除个别海域外,流速均小于20cm/s,是一支较弱的流。但这支流有一明显特征,除在该流源地外,最大流速值是在200m水层或者更深的地方。它的最大宽度约为200km,主要水体集中在700m以浅的水层。我们认为岸形影响是该支流形成的主要原因。

Based on the CTD data gethered by R/V Science I in each October from 1986 to 1990 in the western boundary region of Philippine Sea, we found that there exists a southward coastal current along the eastern coast of the Philippines. Generally, the current is not very strong. Its velocity is less than 20 cm/s. The maximum velocity occurs in the depth of 200 m or more. The width is about 200 km off Catanduanes. The current exists above 700 m.
