欧素英张红，王东晓何杰2007.夏季珠江口附近海域浮羽的水平特征。SI 50（第九届国际海岸研讨会论文集），652 - 657。利用1978 ~ 1984年在澳大利亚黄金海岸进行的现场盐度测量资料，研究了珠江高流量时浮力羽流的水平结构。根据夏季盐度水平分布的特点，将浮烟分为4种类型：近海喇叭状扩散（Ⅰ型）、西沿岸扩散（Ⅱ型）、东近海扩散（Ⅲ型）、东西沿岸扩散（Ⅳ型）。结果表明，烟羽形态随时间变化，呈现明显的月变化和年变化，其中Ⅱ型烟羽多出现在6月，7月烟羽形态很大概率属于Ⅲ型烟羽，且受河流流量和局地风的控制。
ABSTRACT Ou, Su-Ying., Zhang, Hong., Wang, Dong-Xiao. and He, Jie., 2007. Horizontal characteristics of buoyant plume off the Pearl River Estuary during summer. SI 50 (Proceedings of the 9th International Coastal Symposium), 652 – 657. Gold Coast, Australia, ISSN 0749.0208 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 (TypeⅠ), 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.
