摘要
Weddell海作为世界面积最大的边缘海,冬季大部分被海冰覆盖,夏季靠近南极大陆的边缘也有大量海冰。研究海冰的运动,能够在考察活动中有效规避海冰的影响,并且有利于进一步探讨Weddell海区的某些水文特性。本文基于傅里叶变换实现的光流算法,通过遥感图像对海冰运动进行分析,直观的展示出Weddell海区海冰运动的中尺度涡,并从Weddell海潮汐特性,南极海表面风场等方面对海冰运动原因加以猜想和分析。
Weddell Sea,the largest marginal sea in the world,which is most covered with sea ice in winter and there is a large amount of sea ice near the margin of Antarctic continent even in summer. Studying the movement of sea ice can help avoid the influence of sea ice effectively and contribute to further probe into certain hydrological characters in Weddell Sea. This essay is based on the Fourier transform of optical flow algorithm, and analysis of sea ice movement through the remote sensing image,which clearly shows the meso-scale eddy in the sea ice movement in Weddell Sea. Moreover,this article discusses and analyzes the causes of the movement of sea ice from the aspects of the quality of tides of Weddell Sea and wind fields near the surface of the Antarctic seas,etc.
