厄尔尼诺对闽南——台湾浅滩变性水团的影响

摘  要：
笔者曾探讨闽南——台湾浅滩渔场上升流演变及其与渔业的关系。指出,非厄尔尼诺年,夏季在该渔场存在多处上升流,渔业丰收;反之,在厄尔尼诺年,夏季仅存在单一上升流,渔业歉收。厄尔尼诺现象既然会引起上升流结构如此变化,它与变性水团之间究竟存在什么样关系呢?我们根据1975～1976年闽南—台湾浅滩温盐调查资料,并参照一些有关历史资料,对上述问题进行初步分析研究。

摘  要：
A comparison is made on South Fujian-Taiwan Shoal Modified Water Mass in the non-El Nino Year and in the El Nino Year and the results are shown as follows:1. The Kuroshio Sublayer Water (KA) will occur along the outer slope and outer deep bottom layer as a result of the intensifying of the climbing of KA in non-El Nino years, whereas it will disappear in the El Nino Year.2. In non-El Nino Years the bottom of Taiwan Shoal will be occupied by East Guangdong Mixed Water (S_1A), whereas it will be replaced by sunken Guangdong Coastal Water (S_2D) in the El Nino Year.3. Both the centers of gravity in East Guangdong Water and in East Guangdong Mixed Water are relatively low (drop in temperature), and both the ranges are relatively contracted. The center of gravity in (S_2D) will decend lower than that of S_1A, while the ranges of S_1A will be smaller than that of S_2D. This is a very interesting phenomenon.
