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。
Based on the wind gust detection data of Dalian and Panjin high frequency ground wave radar in Liaoning Province and the wind field observation data of the automatic weather station in the coastal area of Liaoning Province, the paper compares the wind farm observation data with the effective sample number, acquisition rate, availability, average deviation and standard deviation And other data, continuous detection of all time and grading wind power assessment of the work of high-frequency ground wave radar to assess the high frequency ground wave radar data inversion of the overall performance. The results show that the overall performance of high frequency ground wave radar in Dalian is better than that of Panjin high frequency ground wave radar. The acquisition performance of wind direction and wind speed data of high frequency ground wave radar in Dalian is equivalent to that of general application, The acquisition rate of wave radar data is basically the same, but the usability of the two data is low, which is different from the actual sea state. In low wind conditions (wind speed less than 6 m · s -1), the wind fields detected by high frequency ground wave radar in Dalian and Panjin deviated from the actual wind field greatly. When the ambient wind pressure exceeded 6 m · s ~ (-1), the detection performance of Dalian high frequency ground wave radar significantly improves, which can reflect the actual wind field changes in general, and the performance of Panjin high frequency ground wave radar is general. When the mean wind power of the environment exceeds 10 m · s -1 ), The detection performance of the high-frequency ground wave radar in Dalian increased significantly.
