| 运用卫星跟踪漂移浮标资料分析南海表层海流,研究了有关海域的表层海流特征。结果表明,秋、冬季入侵南海的黑潮水有一小部分沿台湾南岸折回黑潮主干,并有时在台湾西南外海形成反气旋涡旋,其余大部分黑潮水西行进入南海内部。吕宋岛西部沿岸流始于13°N以南,沿菲律宾西海岸北上抵达吕宋岛西北角,与黑潮水混合后西行。 |

| Abstract: |
| Data of satellite-tracked drifting buoys have been analyzed to infer the mean seasonal surface current and mean seasonal surface temperature of the South China Sea (SCS). The obtained pictures of mean surface current and temperature, based on 0.5°squares, are consistent with earlier studies. There are some buoys flowing into the SCS through the north part of Luzon Strait during autumn and winter but not during the rest of the year. In autumn and winter, a part of the Kuroshio intrusion water retraces near the south of Taiwan, perhaps forming an anti-ayclonic eddy in the outer sea southwest of Taiwan, and finally it rejoins the Kuroshio. While most of the Kuroshio intrusion water flows west into the SCS, and then turns toward the south when it reaches the east of Vietnam, with a maximum velocity of 1.5cm/s to the east of middle Vietnam. The Northwest Luzon Coastal Current starts from the south of 13°N, flowing northward along the west of Philippines with a feature of high temperature, and then it turns toward the west in the outer sea northwest of Luzon, finally combining into the Kuroshio intrusion water. |
