三类测风仪测量近地层小尺度风场比较

A comparison of small scale wind field measurements by three types of anemometers in the near surface layer

用LSF1-1型测风仪测量一分钟一次瞬时风速记录分析表明,该测风仪可以粗略测量比较长周期的风速脉动变化,但精度较差。FL和Dyne测风仪由于它们灵敏度低,精度不够,不太合适测量小尺度风场的脉动变化。

An analysis of the instantaneous wind speed measurements made once every minute by LSF1-1 type anemometer has shown that such kind of instrument can be used to measure the wind speed fluctuation in a longer period while its accuracy is quite low EL and Dyne anemometers are not suitable for measuring wind speed fluctuation in a small-scale wind field because of their low precision and sensitivity.
