一、引言近年来,笔者曾探讨过厄尔尼诺现象和在闽南—台湾浅滩渔场上升流演变的关系,发现了在厄尔尼诺年夏季(除了次级厄尔尼诺年如1969年和厄尔尼诺年如1965,1966年8—9月外),在东山站出现表层盐度(按月平均值)较低。众所周知,厄尔尼诺现象是一种非周期性,全球性的海—气异常现象,不会仅局限于某一站水文要素异常的变化,也许还会涉及范围广些,闽浙沿岸夏季表层盐度变化规律如何?与厄尔尼诺现象有关? 日前人们对于厄尔尼诺现象预报还没有找到切实可行方法,还在很艰苦探索中。但是,为
I. INTRODUCTION In recent years, the author has discussed the relationship between the El Niño phenomenon and the upwelling of the Taiwanese shoal fishery in the southern part of Taiwan. It was found that during the El Niño summer (except for the secondary El Niño years such as 1969 and El Niño 1965, 1966 8- September), surface salinities at Dongshan Station (monthly average) lower. It is well-known that the El Niño phenomenon is an aperiodic and global anomaly of the sea-atmosphere. It is not limited to the anomalous changes of the hydrological elements of a certain station. It may also involve a wide range of changes in summer surface salinity along the coasts of Fujian and Zhejiang How is the law related to El Niño? Recently, people have not found a feasible method for the El Niño phenomenon forecast, and they are still exploring it with arduous efforts. But for
