摘　　要：利用2011年7月的高频地波雷达观测与现场同步常规观测资料和卫星风场资料,分析南黄海辐射沙脊群夏季表层余流特征.结果表明,南黄海辐射沙脊群近岸海域的表层余流向海辐散,外围海域的夏季表层余流向北.南黄海辐射沙脊群近岸海域表层余流的辐散格局主要受潮波与沙脊群水下地形的相互作用影响,外围海域夏季的北向表层余流格局主要受风场的控制.高频地波雷达观测的余流场为南黄海西部夏季浒苔迁移和平面分布的解释提供了佐证.Surface current field over radial sand ridge field in the south Yellow Sea was analyzed based on the data collected by using the shore-based high frequency radar and the Acoustic Doppler Current Profiler（ADCP）in July 2011 and the QSCAT wind data.In near-shore shallow water,the residual current was radially offshore;in far-shore deep water,the residual current was northward.In far-shore deep water,the current pattern was mainly influenced by the wind,while in near-shore shallow water the current pattern was due to the influence of the interaction of underlyingbathymetry and tide waves.The HF Radar survey is suitable for trends analysis of long-term current field.The result supports the hypothesis that the green algae enteromorpha prolifera came from Jiangsu coast and subsequently expanded to the southern Yellow Sea.
