摘　　要：文章利用2020-2021年EZC超声波测风仪和EL15-C风速风向传感器平行观测资料,采用相关性、均方根偏差、一致性等统计方法,对比分析了超声波测风仪的测风性能。结果表明:1)EZC超声波测风仪与EL15-C风速风向传感器有较好的相关性。2)风速和风向偏差分布存在明显的季节变化,其中夏季分布最集中;随着风速的增大,风向偏差分布愈趋集中。3)风速和风向一致率均是夏季最高,N和S方位上风向一致率最高;小风速下风速一致率较高,随着风速的增加一致率逐渐降低。By utilizing the parallel observation data from EZC ultrasonic wind meter and EL15-C wind speed and direction sensor from 2020 to 2021 and adopting the statistical methods such as correlation,root-mean-square deviation and consistency,this paper compares and analyzes the wind measurement performance of ultrasonic wind meter.The results show that:1)good correlation exists between ultrasonic wind meter and EL15-C wind speed and direction sensor;2)the obvious seasonal changes exist in the distribution of wind speed and direction deviations,and the distribution in summer is most concentrated;along with the increase of wind speed,the distribution of wind direction deviations tends to be concentrated;3)both the consistency rate of wind speed and that of wind direction can reach their maximum in summer and the maximum consistency rate of wind direction can be obtained in N and S orientations;relatively higher consistency rate can be achieved for light wind speed and down wind speed;and the consistency rate will become reduced gradually along with the increase of wind speed.
