本文应用1980—1981年的上升流专题调查资料和有关历史资料讨论了浙江沿岸上升流区的锋面结构特征、混合状况、位置变动的特点及其原因。本文认为,浙江沿岸锋和上升流锋的位置变动大致可归因于台湾暖流强度和位置的变动,风也是一个重要因素,浙江沿岸的上升流还受到浙江近海海底地形特征和台湾暖流的影响,Janowitz等提出的地形引起的上升流理论可以应用于浙江近海。
This paper discusses the characteristics of the frontal structure, the mixing conditions, the characteristics of the location changes and their causes in the upwelling area along the coast of Zhejiang Province from 1980 to 1981 by the upwelling survey data and historical data. This paper argues that the change of the location of front and updraft front in Zhejiang coast can be roughly attributed to the change of intensity and location of the warm current in Taiwan. Wind is also an important factor. The upwelling of Zhejiang coast is also affected by the topographic features of offshore Zhejiang and the warm current of Taiwan. The terrain-induced upwelling theory proposed by Janowitz et al. Can be applied to Zhejiang offshore.
