介绍了海洋动力学模式中的同化技术，探讨了在海洋动力学模式中同化单站高频地波雷达探测的海流径向速度反演探测区表层海流的可行性。基于伴随同化和POM模式，利用单站高频地波雷达成功地反演了舟山海域的表层海流。并将单站高频雷达反演结果与双基地高频雷达合成结果和安德拉海流计定点观测结果进行了比较。误差分析表明，基于伴随同化和POM模式获取单站高频雷达流速和流向数据是可行的，所获得的数据与高频雷达观测的流场具有较高的相关性和一致性。
This paper introduces the assimilation technology in an ocean dynamics model and discusses the feasibility of inverting the sea surface current in the detection zone by assimilating the sea current radial velocity detected by single station HF ground wave radar in ocean dynamics model. Based on the adjoint assimilation and POM model, the paper successfully inverts the sea surface current through single station HF ground wave radar in the Zhoushan sea area. The single station HF radar inversion results are also compared with the bistatic HF radar composite results and the fixed point measured results by Annderaa current meter. The error analysis shows that acquisition of flow velocity and flow direction data from the single station HF radar based on adjoint assimilation and POM model is viable and the data obtained have a high correlation and consistency with the flow field observed by HF radar.
