Abstract 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.
