【摘要】 2008年9月24日,在内蒙古锡林浩特国家气候观象台,利用气候观象台的100m风能梯度塔、北京爱尔达电子设备有限公司的1290M移动边界层风廓线雷达(Airda3000型)以及江西省气象科学研究所研制的微型无人驾驶探空飞机进行了三种探测设备测风精度的对比试验。试验获取了多组有效的对比数据,本文通过两利,方式对获得数据进行比较分析。结果表明风能梯度塔数据稳定可靠,耗资低,但探测高度低,范围小;风廓线雷达具有实时性、探测高度高的优势,但得到的是探测范围内风的平均值,较其它两组数据明显偏小;微型探空飞机最大的特点是可人为控制飞机航线,探测方式灵活,且探测数据与风能梯度塔的观测数据相差不大,有较大的应用空间。更多还原

【Abstract】 September 24,2008,in Xilinhot,Inner Mongolia National Climate Observatory,we carried out a test to compare the measurement precision of three types of wind detection equipments,the observatory’s 100m Wind Energy Gradient Observation Tower,Beijing Airda’s 1290M Mobile Boundary Layer Wind Profiler(Airda3000) and the Micro-Sounding Unmanned Aircraft developed by Jiangxi Institute of Meteorological Science.We obtained many valid comparative data,which had been analyzed by two ways.The results show that the data of Wind Energy Gradient Observation Tower are stable,reliable and low-cost,but low-altitude and small-range; Wind Profiler has the advantage of real-time and high-altitude,but the data are the average of the wind within its detection range,clearly smaller than those of the other two equipments;the largest character of Micro-Sounding Aircraft is that its flight course can be controlled and detection manner is flexible,the detected data are more or less the same as those detected by Wind Energy Gradient Observation Tower.So the Micro-Sounding Aircraft has greater application space.更多还原
