摘　　要：通过分析高频地波雷达所在探测海域内浮标观测的有效波高和风速数据,建立了海面风速与有效波高的经验模型。利用二范数最小方法对该模型的参数进行估计,实验结果表明了该模型的稳定性。将所提模型应用到高频地波雷达OSMAR071数据处理中,6个月数据连续反演结果与浮标给出的风速吻合度高,表明了该风速反演经验模型的有效性。An empirical model of ocean surface wind speed and significant wave height relation is proposed by analyzing data obtained by buoy in-situ observations at the coverage of radar beam.The model′s parameters are estimated by minimum standard Euclidean norm method from six months′ buoy in-situ measuring data and the estimation results show the model′s stability.The wind and wave model is applied to HFSWR OSMAR071′s wind speed inversion.Compared with four months′ buoy in-situ observation wind speed,the correlation coefficient is 0.6 and the RMSE is 2.7 m·s-1 which confirmes the model′s availability,which verifies the validation of the empirical wind speed inversion.
