中文摘要：

海洋表面盐度（Sea Surface Salinity, SSS）是海洋的重要物理和化学参量, SSS的时空分布与全球大洋环流和水汽循环密切相关。本文基于美国国家航空航天局（NASA）发射的Aquarius卫星3 a的SSS遥感数据,给出了孟加拉湾及其附近海域海表盐度的空间分布特征,并重点分析了影响孟加拉湾海表盐度变化的可能因素。研究结果从一个侧面说明了利用Aquarius卫星遥感观测海洋大尺度盐度变化的可行性。

英文摘要：

Sea surface salinity （SSS） is an important physical and chemical parameter because its distribution is connected with the general circulation and water cycle in the world. Based on three years of satellite remote sensing data from Aquarius Mission of American National Aeronautics and Space Administration, the spatial and temporal distributions of the SSS in the Bay of Bengal and its adjacent waters are presented in this paper, and the related factors that influence the characteristics of the SSS are further analyzed. This study has demonstrated the feasibility of revealing the large-scale variability of the SSS using the Aquarius data.
