| 摘要: |
| 以考虑了地转和均匀背景流场影响的两层流体界面内波频散关系 模型为基础,得到新的利用SAR遥感图像计算混合层深度的方法。利用该方法对一幅南海北部SAR内波图像进行了实例研究,并且和时空同步的CTD资料进行 了对比。结果表明,加入地转和均匀背景流场影响的模型更为合理,为更准确地反演混合层深度奠定了基础。 |

| Influences of Coriolis force and steady uniform currents on mixed-layer depth retrieved from SAR image |

| Abstract: |
| The new methods are presented to estimate the mixed-layer depth from synthetic aperture rader(SAR) image based on the dispersion relationships obtained by using the two-layer fluid model of oceanic internal waves when the effects of Coriolis forces and steady uniform currents are considered. A internal solitary wave captured by the SAR image in the north South China Sea is analyzed by the proposed inversion methods. Comparing the result with synchronized CTD data, it is shown that the models with the effect of Coriolis force and steady uniform currents are more reasonable. |
