摘要 给出了5种UHF风廓线雷达降水数据的判别方法,利用北京CFL-16型对流层风廓线雷达于2007年6—8月获取的部分观测数据,对5种判别方法进行对比分析。结果表明,这些方法在降水天气下判断正确率都在89%以上,其中,建立关于垂直径向速度和信噪比、垂直径向速度和谱宽的判别函数两种方法判断正确率均达99%以上。 Based on the data from the CFL-16 wind profiler in Beijing from June to August in 2007, five analysis methods of UHF wind profiler data are compared. The results show that accuracy of all the five methods are over 89% in case of precipitation, among which the accuracy of the methods of plotting vertical radial velocities against vertical beam SNRs and against spectra widths are over 99 %.
