| 摘 要： | 本文依据1983,1984,1987,1988几年的有关资料,利用“对应分析法”对台湾海峡中、北部海域春、夏季(5—8月)的水团及有关问题进行了分析。结果表明:(1)5—8月间该海域存在两种水团分布类型,其中5月属冬季型,全海域存在浙闽沿岸水和海峡暖流水两个水团;6—8月属夏季型,全海域均为海峡暖流水盘踞,按温度不同,它又分为上层水和深层水两部分。(2)浙闽沿岸水具低温、低盐、高溶解氧特征,均一性较差,年际变异较大;海峡暖流水以高盐为主要特征,温、盐度和溶解氧分布较均匀,且诸特征相对稳定。(3)海峡东、西两侧均存在上升流现象,西侧的上升流出现于6—8月,中心在海潭岛附近;东侧的上升流7月见于澎湖群岛北方海区。(4)6—8月间,海峡暖流深层水(核心)主要沿海峡偏西一侧北上,而不是紧靠东侧径直向北。

| Abstract: | This paper analyses the water mass in the middle and northern Taiwan Strait in spring and summer (May-August) and other related problems by using "the comparison analysis method." The results are given below. 1) There are two distributive types of water mass in this area between May and August, the winter type in May and the summer type in June-August. Two water masses exist in the whole area in May, namely, the Zhemin Coast Water and the Strait Warm Current Water. From June to August, the whole area is all occupied by the Strait Warm Current Water and according to different temperature and salinity, it can be divided again into two parts, upper water and deep water. 2) The Zhemin Coast Water is of characteristics of lower temperature, lower salinity and higher disolved oxygen. Irs uniformity is poorer and interannual variations are greater. The Strait Warm Current Water is mainly characterized by its higher salinity. And temperature, salinity and disolved oxygen are homogeneously distributed. 3) There are some upwelling phenomena in both east and west sides of the Strait. The upwelliing on the west sides appears between June and August and its centre is in the area near the Haitan Island but the upwelling on the east side is found in the north of the Penghu Islands in July. 4) The Strait WarmCurrent Deep Water (core) mainly goes northwards along the west side of the centreline of the Strait instead of flowing straight to the north closely by the east side of the Strait between June and August. |
