| 摘 要： | 基于球载式下投北斗探空仪测风观测试验，建立了针对下投式的测风试验评估方法.试验结果表明上升段北斗测风的准确度接近RS92探空仪的探测准确度要求，两者一致性较好；下降段RS92测风误差基本上与上升段的属于同一量级水平，下降初期测风数据在使用时需要做预处理或者有效控制；下降段BD探空仪测风误差与下降段RS92的基本相当，除了球炸初期外，基本上接近WMO的测量要求，此外初期的急速下降对导航定位测风提出了更高的技术要求.整体而言，球载式下投探空观测在时间上可以实现对原有的1次探空进行加密，在空间上可以增加1个区域的探测，并为对现有探空站网分布进行合理优化提供依据，具有良好的应用前景.

| Abstract: | Based on observation tests of the domestic BD sounding of ball loading,a method for the evaluation of wind measurement was established.The test results showed that the accuracy of BD wind was nearly the same as that of RS92 at ascent stage,and the consistency was in good agreement.The errors of the RS92 wind at descent stage and ascent stage were of the same magnitude.The initial part of the descent stage wind data needed to be pretreated or controlled when it was used.The error of the decline period of BD wind was generally the same as that of the RS92 at descent stage,except for the initial explosion of the ball.Essentially,it was close to the measurement requirements of WMO.Meanwhile,the rapid decline brought higher technical requirements to positioning.In addition,BD dropsonde of ball-loading could encrypt an original sounding in terms of time and optimize the existing sounding station network in terms of space,which would have better application potential. |
