高分三号(GF\|3)SAR遥感卫星的发射为内波的深入研究提供了丰富图像资料,利用其高空间分辨率和大幅宽成像的优势,能够对南中国海东沙岛附近的内波开展振幅和波速的高精度反演。采用高阶完全非线性薛定谔方程描述内波,建立反演振幅和波速的模型。收集2017年5月至8月南海东沙岛附近的GF\|3遥感图像,探究南海陆坡处内波的振幅和传播速度演变。理论模型计算出的结果与2013年该研究区域的实测数据对比,发现反演振幅大小基本与实测相近。内波自东向西传播过程中,水深变浅,非线性作用增强,频散作用减弱,振幅和传播速度都不断减小。这为定量研究内波的能量输送、耗散以及未来的预报工作提供依据。

GF\|3 microwave remote sensing satellite provides abundant image data for deep research of internal waves.With the advantages of high spatial resolution and wide range imaging,high precision inversion of amplitude and velocity of internal waves near Dongsha Atoll in the South China Sea was conducted.The high order fully nonlinear Schrodinger equation was used to describe internal waves,and an inversion model of amplitude and wave velocity was established.GF\|3 remote sensing images of internal wave from August 2016 to August 2017 near Dongsha Atoll were collected,which aims to explore the revolution of amplitude and propagation velocity at the continental slope of the South China Sea.The calculated results of theoretical model were compared with the measured data of the study area in 2013.The inversion amplitude was similar to the measured value.During the propagation process of internal waves from east to west,the water depth becomes shallower,the nonlinear effect is enhanced,the dispersion effect is weakened,both amplitude and propagation velocity decrease.This offers the references for quantitative study of the energy transportation,dissipation and future prediction of internal waves.
