| 摘 要： | 文中对多普勒声雷达测风和325 m铁塔上风速、风向仪及超声风速仪的测量值进行了观测比较。结果表明,当信噪比大于1时,两种方法测量的平均风速、风向的相关较好,风速、风向廓线较为接近;声雷达测量的垂直风速平均值和均方根差比超声风速仪的测量值略偏大。这与国外进行的观测比较结果一致。 需要指出,声雷达和直接测量仪器的观测比较中存在一定差异,特别是对比每一次的观测值就可以看出,在某些情况下还存在明显差异。进一步分析声雷达测风产生偏差的原因,对误差做出合理的订正是十分必要的。

| Abstract: | In tiiis paper the wind speed and wind direction are compared by Doppler Sodar and in-situ measurements on 325 m meteor ological tower. When the ratio of signal to noise larger than 1,the mean wind speed and wind direction are correlated very well by the two methods, the profiles of wind speed and wind direction are close too. The mean value and root mean square of vertical velocity measured by Doppler Sodar are little bid larger than the value measured by sonic anemometer at 85 m height. The observational results are in correpondence with other four Doppler Sodar which compared with BAO tower measurements. We noticed that there are some difference in the observational results between the Doppler Sodar and in-situ measurements, especially compared with the value measured by every times. Therefor it is important to analaze the reason for the difference measured by these tv}o methods and to make correction for the Boppler Sodar. |
