摘要： 基于辽宁省大连和盘锦高频地波雷达的海上大风探测资料，与辽宁省沿岸海域区域自动气象站的风场观测资料进行对比分析，利用有效样本数、获取率、可用性、平均偏差及标准差等数据，采用连续探测全部时间和分级处理风力评估高频地波雷达的工作状态，评判高频地波雷达资料反演的总体性能。结果表明：大连高频地波雷达的总体性能优于盘锦高频地波雷达；大连高频地波雷达风向和风速观测资料的获取性能相当，总体基本满足业务应用需求；盘锦和大连高频地波雷达资料的获取率基本持平，但二者数据的可用性均较低，与实际海况存在一定的差异。在低环境风力情况下（风速小于6 m·s-1），大连和盘锦高频地波雷达探测的风场均与实际风场偏差较大；当环境风力超过6 m·s-1时，大连高频地波雷达的的探测性能显著提高，可以整体反应实际风场的变化，盘锦高频地波雷达表现一般；当环境平均风力超过10 m·s-1时，大连高频地波雷达的探测性能显著提高。

Abstract: Using the sea gale data detected by the high-frequency ground wave radar (HFGWR) in Dalian and Panjin cities and the wind data from the automatic meteorological stations along the coastal regions in Liaoning province,the retrieval results of HFGWR were evaluated based on analyzing the numbers of effective samples,acquisition rates,usability,average deviation,and standard deviation indices.The working situations of HFGWR were judged by the continuous detecting time and grading level of wind force.The results show that the overall performance of HFGWR in Dalian is better than that in Panjin.The acquisition abilities to wind direction and wind speed data in Dalian are equal,and basically satisfy the needs of operation and application.The radar data acquisition rate in Panjin is mainly in agreement with that in Dalian,but the usability of these data is relatively low;there is a certain gap from the real sea situation.Under a weak wind condition with wind speed less than 6 m·s-1,the wind fields detected by HFGWR in Dalian and Panjin both demonstrate a larger deviation from the real wind fields.When the wind speed is more than 6 m·s-1,the detecting ability of radar in Dalian is significantly improved and the detecting result generally reflects the actual wind change situation,while that in Panjin is not good enough.When the wind speed is more than 10 m·s-1,the detecting ability of radar in Dalian can be further improved.
