台湾海峡是连接南海和东海的唯一通道，在南海和东海的物质交流中起着关键作用。然而，在东北季风期间，当恶劣天气阻碍船上测量时，该地区的采样率很低。本研究利用高时空分辨率的地球同步海洋水色成像仪（GOCI）反演台湾海峡及邻近东海的表层环流。卫星观测受到云层的限制。然而，它们提供了唯一的表面流观测有用的假设检验。结果表明，瞬态表面流可以分为三个区域：西南流的强风，东北流的弱风，和两岸流的中风。卫星观测在验证模型海流方面也很有价值。两个高分辨率的全球海洋再分析产品，混合坐标海洋模式（HYCOM）和哥白尼海洋环境监测服务（CMEMS），检查。再分析结果与卫星观测结果基本一致。此外，CMEMS显示出上级的性能。这项研究说明了地球静止海洋颜色卫星在提供空间广泛的表面流观测在广阔的大陆架地区，目前米数据稀疏或不存在的独特能力。
The Taiwan Strait is the only channel connecting the South China Sea (SCS) and the East China Sea (ECS), and plays a key role in the material exchanges between SCS and ECS. The region however is poorly sampled during the northeast (NE) monsoon when severe weather hinders shipboard measurements. In this study, the surface circulations in the Taiwan Strait and the adjacent East China Sea are derived from the Geostationary Ocean Color Imager (GOCI) with a high spatiotemporal resolution. The satellite observations are limited by cloud over. Nevertheless, they provide the only surface flow observations useful in hypothesis testing. It is demonstrated that the transient surface currents can be classified into three regimes: a southwestward flow for strong winds, a northeastward flow for weak winds, and a cross-strait flow for moderate winds. The satellite observations are also valuable in validating model currents. Two high-resolution global ocean reanalysis products, the Hybrid Coordinate Ocean Model (HYCOM) and the Copernicus Marine Environment Monitoring Service (CMEMS), are examined. The reanalysis products are generally consistent with the satellite observations. The CMEMS moreover shows a superior performance. This study illustrates the unique capability of the geostationary ocean color satellite in providing spatially extensive surface flow observations in broad shelf regions where current meter data are sparse or non-existent.
