| 摘要: |
| 针对海洋实测流速资料极其匮乏的事实, 利用2004 年1 月~2009 年12 月月平均的Argo 温盐格点资料, 结合改进的P-vector 方法重构北太平洋绝对地转流流场。与卫星高度计和实测流速的比较以及相关性分析表明, 重构的绝对地转流是可信的, 可以用来研究不同大尺度环流特征及其动力结构。可以为研究海洋动力过程和气候变化提供一套有用的流场数据。 |

| Calculation of absolute geostrophic velocity of the North Pacific Ocean based on Argo profiles |
|
|
| Abstract: |
| Materials of measured velocity in the ocean are quite few. In this paper, the absolute geostrophic currents in the North Pacific Ocean were reconstructed with newly gridded Argo profiling float data from 2004 to 2009 based on improved P-vector method. The comparison analysis with the altimeter geostrophic currents and the TRITON(Triangle Trans-Ocean Buoy Network) moored current data and the relevance analysis suggest that the reconstructed absolute geostrophic velocity is reliable and can be used to study the large-scale circulation chaacteristic and its dynamic structure. |
