| 摘 要： | 利用GLC-24型风廓线雷达的5波束观测数据,分析了在晴空和降水条件下风廓线雷达探测的准确性,得出结论如下:在晴空条件下大气均匀稳定、垂直速度很小,风廓线雷达测量水平风的准确性高;在均匀性降水条件下,虽然垂直速度很大,但大气在风廓线雷达5波束探测的水平范围内均匀,风廓线雷达测量水平风的准确性也较好;在非均匀性降水条件下,大气在风廓线雷达探测的水平范围内不均匀,不符合风廓线雷达计算水平风的假设条件,需要进一步改进算法,减少计算误差。

| Abstract: | The five beam observation data of the GLC 24 wind profiler are used to analyze the detection accuracy of wind profilers under clear and precipitation conditions, respectively. The results show that in clear weather wind profilers have a high detection accuracy on horizontal winds because the atmosphere is uniform and steady with a small vertical speed, while under the condition of uniform precipitation, even with a large vertical speed, wind profilers also have a good detection accuracy on horizontal winds because the atmosphere was relatively uniform within the detecting range of five beams, and under the condition of no uniform precipitation, in which the assumption of horizontal wind calculation of the wind profiler is unsatisfied, the algorithm should be improved to reduce calculating errors. |
