洋流的影响及南海–北印度洋海流特征
Influence of Ocean Current and Its Characteristics in the North Indian Ocean and South China Sea

本文首先从洋流的定义与分类、洋流对人类生产生活的影响、与洋流密切相关的经典战例、现代战争中洋流对于海战的影响多角度出发介绍洋流，并利用来自美国马里兰大学开发的全球简单海洋资料同化分析系统(SODA: Simple Ocean Data Assimiltion)产生的海流数据，分析了南海和北印度洋的海流场特征，结果表明：相较于南印度洋地区的海流场，北印度洋地区及中国南海地区的海流场具有明显的季风特点。
This paper first introduces ocean currents from the perspectives of the definition and classification of ocean currents, the impact of ocean currents on human production and life, the classic battles closely related to ocean currents, and the impact of ocean currents on naval battles in modern wars. By using the current data generated by the Global Simple Ocean Data Assimilation Analysis System (SODA: Simple Ocean Data Assimilation) developed by the University of Maryland, the characteristics of ocean currents in the South China Sea and North India are ana-lyzed. The results show that compared with the South Indian Ocean, the North Indian Ocean and the South China Sea have obvious monsoon characteristics.
