做好風廓線雷達水平風探測數據與氣球探空的對比分析，對于更進一步用好這種儀器十分必要。采用北京南郊2014—2018年5年探空資料，對該站同期風廓線雷達〖JP2〗水平風資料從總體平均、早中晚、不同天空狀況及平均年變化等方面進行對比分析。結果表明：①5年平均均方根誤差U分量在2.2~5.0 m/s之間，V分量在2.3~3.6 m/s〖JP〗之間，均在850 hPa高度最小。平均誤差U分量均為負，表明近5年風廓線雷達所測U分量比氣球探空的偏小；且隨高度其絕對值是增大的。V分量僅在700 hPa高度為負，也在該高度最小。U、V分量分別在500 hPa和850 hPa高度相似程度最好。5年綜合來看，850和700 hPa高度風與氣球探空更接近。②中午誤差低于早晚，這與中午大氣湍流比較強盛有關。③云量較多時誤差相對較小，云量少時（特別是晴空）誤差較大，反映出這種儀器對濕度比較敏感。④夏季或夏半年U、V分量與氣球探空的差異較小、相似程度好，尤以6或7月最突出；冬季或冬半年差異較大、相似程度較差，尤以12或1月明顯。這在實際業務和科研使用時需注意。
It is necessary for further making use of the measurements to conduct the comprehensive comparison of wind profiler horizontal wind against radiosonde data. Based on the 5year collocated wind speed data from radiosondes and wind profilers in Beijing, the wind profiler data are carefully analyzed, including total average, diurnal and annual variations, different sky conditions. The results show that the root mean square error of 5year average 〖WTBX〗U〖WTBZ〗component was from 2.2 to 5.0 m/s, the 〖WTBX〗V〖WTBZ〗component from 2.3 to 3.6 m/s, and the 〖WTBX〗U〖WTBZ〗component and 〖WTBX〗V〖WTBZ〗component minimum deviation occurred at 850 hPa. The 〖WTBX〗U〖WTBZ〗component average error of different heights was negative, which indicates the wind profiler 〖WTBX〗U〖WTBZ〗component wind speed is smaller than that of balloon sounding, and the absolute value of error increased with height. The 〖WTBX〗V〖WTBZ〗component average errors were negative only at 700 hPa. The similarity of 〖WTBX〗U〖WTBZ〗component at 500 hPa was the best and that of 〖WTBX〗V〖WTBZ〗 component wind at 850 hPa was the best. On average, the wind profiler wind was closer to balloon sounding at 850 hPa and 700 hPa. The errors in the 〖WTBX〗U〖WTBZ〗 and 〖WTBX〗V〖WTBZ〗 components at 14:00 were relatively smaller than those at 08:00 and 20:00, which was related to the strong atmospheric turbulence at noon. The errors were relatively small when the amount of clouds was large, and large when the amount of clouds was small (especially in clear sky). which indicates the wind profiler is sensitive to humidity. The 〖WTBX〗U〖WTBZ〗 and 〖WTBX〗V〖WTBZ〗 components have little difference and good similarity with balloon sounding in summer or summer half year, especially in June and July, and large difference and bad similarity in winter or winter half year, especially in December and January. This should be paid enough attention in forecast operation use and scientific researches.
