| 摘 要： | 随着高空探测自动化水平和仪器精度的不断提高,气象探测数据也越来越精确,为了提高高空风探测结果的准确性和完整性,解决实际工作中因计算方法不适合、数据平滑误差等原因引起的数据错误或量得风层缺测等问题,提出利用L波段雷达测风秒数据进行风向判断弥补缺测数据,利用内插方法计算斜距减小人为误差等方法。这些方法在实际工作中取得了较好的效果,可以有效减少数据缺测和误差偏大现象,提高了高空气象探测数据的质量。

| Abstract: | With the improvement of the automation level of radiosonde sounding and its precision, the sounding data have become more accurate. In order to improve the precision and integrity of wind finding data and solve the problems caused by error data or unsuitable computing methods, a method is proposed, in which the second wind finding data can be used to judge the wind direction, together with calculating quantity wind layer, and the slope distance is calculated by using interpolation technique to reduce the man made errors. Good results are obtained in the actual work, and the phenomena of data missing reduced significantly. |
