摘　　要：在文［９］［１０］关于西北太平洋海面动力地形研究的基础上，本文对该海域表层密度流进行了初步探索。特别是用０．５°×０．５°方区多年船测资料，对西部边界流——黑潮进行了专门研究。结果表明，该海域表面密度流模式与主要由风驱动的大洋总的环流模式基本一致。据研究结果，对文［９］给出的海面动力地形和全球海面动力地形的某些特征作出了解释。另外，还就卫星测高在确定大洋环流的局限性和若干概念性问题提出了明确的看法。Based on the investigation of the sea surface dynamic topography of Northwest Pacific area,the research on the surface density current (SDC) in the area has been conducted, especially on the Western Boundary Currents (Kuroshio) using 0.5°×0.5° grids surfaceship ocean data. The research results show there are no obvious difference in essence between the models of SDC and the general circulation of the oceans drived basically by wind. The mechanism which causes the anomaly of the sea surface dynamic topography and some features in the global ocean area is also explained in the paper. Meanwhile, the limitations of the Satellite altimetry in the determination of the general circulation of the oceans, along with some important concepts concerned are discussed.
