中文摘要:
      利用江西省永修县吉山铁塔50 m处CSAT3三维超声风速仪和常规仪器的风观测资料,以及铁塔附近气象观测站同期降水资料,通过对比分析,检验了超声风速仪水平风观测资料质量,还考察了降水(降水强度大于3 mm/h)对观测资料质量的影响。结果表明:超声风速仪观测的水平风速的数值和演变趋势与实际基本一致;超声风速仪观测的风向方位和高频区分布与实际基本吻合。降水期间,风速和风向观测结果与实际仍然一致,降水对超声风速仪的水平风观测资料质量影响不大。
Abstract:
      The quality of wind observation data of CSAT3 three dimensional ultrasonic anemometer was tested, and the influence of precipitation (precipitation intensity greater than 3 mm/h) on the quality of observation data was also investigated 〖JP1〗through comparative analysis by using the wind observation data of ultrasonic anemometer and conventional instruments at 50 m〖JP〗 in Jishan tower of Yongxiu county, Jiangxi province, and the precipitation data of meteorological observation station near the tower. The results show that the value and evolution trend of the horizontal wind speed observed by the ultrasonic anemometer are basically consistent with the actual situation; the azimuth and high frequency area distribution of the wind direction observed by the ultrasonic anemometer are also consistent with the actual situation. During the precipitation period, the observation results of wind speed and wind direction are still consistent with the actual situation, and the precipitation has little effect on the quality of the horizontal wind observation data of the ultrasonic anemometer.
