【摘要】：收集高分一号光学遥感图像对南中国海东沙岛北部第二模态内孤立波进行研究,对2014年4月至10月期间的光学遥感图像处理.结果表明:第二模态内孤立波分布在东沙岛的北部,在第一模态内孤立波后方;与第一模态内孤立波相比,第二模态内孤立波的波峰线短,长度约为第一模态的20%至40%;第二模态内孤立波的表面亮暗间距小,宽度约为第一模态的10%至50%.高分辨率光学遥感图像可用于第二模态内孤立波精细结构的研究,为定量研究内孤立波的能量传播、破碎和耗散提供依据.
[Abstract]:The optical remote sensing images of Gao Fian 1 were collected to study the second mode internal solitary waves in the northern part of East Sha Island, South China Sea, and the optical remote sensing images were processed from April to October 2014. The results show that the second mode solitary wave is distributed in the northern part of Dongsha Island behind the first mode solitary wave, and the peak line of the second mode solitary wave is shorter than that of the first mode solitary wave. The length of the first mode is about 20% to 40% of that of the first mode, and the width of the solitary wave in the second mode is about 10% to 50% of that of the first mode. The high-resolution optical remote sensing images can be used to study the fine structure of the second mode internal solitary wave, which provides the basis for the quantitative study of the energy propagation, fragmentation and dissipation of the internal solitary wave.
