摘要
将巢湖市气象台超声波测风仪的风速观测资料与同一观测场的自动站测风仪的风速观测资料进行对比，发现超声波测风仪的风速要低约20％；两种仪器风速的日变化规律与气候变化规律基本一致。绝大多数个例的风速标准差小于1m／s，相关系数大于0．5。
Compare wind speed observation data measured by ultrasonic wind instrument of ,Chaohu Observatory with that of automatic meteorological station placed in the same observation field. The result indicates that Ultrasonic wind was lower than automatic station. The day change rule corresponds with Climate change law. The vast majority of wind speed standard deviation less than 1 m/s, correlation coefficient is more than 0. 5.
