Abstract

Field measurements of salinity from 1978 to 1984 are used to investigate the horizontal structure of the Pearl River buoyant plume during high river discharge. According to the characteristics of horizontal salinity distribution in summer, buoyant plumes are classified into four types - offshore bugle spreading (Typel), west alongshore spreading (TypeII), East offshore spreading (Type III), western and eastern alongshore spreading (Type IV). It is found that the plume shapes vary with time, presenting obvious monthly and annual variations and TypeIIalways occur in June, while in July the plume type has very high probability belong to Type III which controlled by river discharge and local wind.

夏季珠江口浮游羽流的水平特征

利用 1978 年至 1984 年的实地盐度测量数据，研究了珠江大流量时浮力卷流的水平结构。根据夏季盐度水平分布的特点，将浮力羽流分为四种类型--离岸角扩张型（Typel）、西部沿岸扩张型（TypII）、东部离岸扩张型（TypIII）、西部和东部沿岸扩张型（Typ IV）。研究发现，羽流形状随时间变化，呈现出明显的月度和年度变化，Ⅱ型始终出现在 6 月，而在 7 月，羽流类型极有可能属于Ⅲ型，它受河流排水量和当地风力的控制。

期刊介绍： The Journal of Coastal Research (JCR) is one of the leading international journals for coastal studies and processes, and is published bi-monthly by the Coastal Education & Research Foundation [CERF]. By covering the entire field of coastal research, the JCR encompasses all subjects relevant to natural and engineered environments (freshwater, brackish, or marine) and the protection/management of their resources in the vicinity of coastlines of the world. Even though the journal broadly focuses on immediate shoreline zones, the JCR also embraces those coastal environments that either reach some indefinite distance inland or that extend seaward beyond the outer margins of the sublittoral (neritic) zone. The JCR disseminates accurate information to both the public and research specialists around the world on all aspects of coastal issues in an effort to maintain or improve the quality of our planet''s shoreline resources.
