摘要: 精确观测大气风场在气象、军事、航空航天等领域具有十分重要的意义。相干测风激光雷达能够实时有效地 进行大气矢量风场探测。为此研制出一款基于多普勒原理的相干测风激光雷达, 并进行外场观测验证了其性能。该 系统可探测垂直上空45~3000 m的水平风场以及垂直气流, 最大可探测风速为60 m/s。分析比对了该雷达于2021 年 10 月16 日08:00―20 日00:00 在广州市黄埔区气象局观测的数据与同时段同地点微波风廓线雷达的观测数据, 结果 表明二者具有良好的一致性。重点分析了2021 年10 月18 日10:00―20 日00:00 的典型观测数据, 进一步验证了该相 干测风激光雷达所测数据的准确性。该雷达在风场探测上的应用将为气象参数监测和预报精度的提高以及极端灾害 性天气的预警提供实时数据支撑。

Abstract: Accurate observation of atmospheric wind field is of great significance in meteorology, military, aerospace and other fields. Coherent wind lidar can detect the atmospheric vector wind field effectively and in real time. A coherent wind lidar based on the Doppler principle is developed in this work, and its performance is demonstrated in field observations. The system can detect the horizontal wind field and vertical airflow with a vertical altitude from 45 m to 3000 m and its maximum detectable wind speed is 60 m/s. The observation data of the lidar at Huangpu District Meteorological Bureau in Guangzhou, China, from 08:00 on October 16, 2021 to 00:00 on October 20, 2021, is analyzed and compared with that of the microwave wind profile lidar at the same location during the same period, and it shows that the two observation data are in good agreement. Finally, the typical observation data from 10:00 on October 18 to 00:00 on October 20, 2021, are selected for key analysis to further verify the accuracy of the data measured by the coherent wind lidar. The application of the developed lidar in wind field detection will provide realtime data support for the improvement of meteorological parameter monitoring and forecast accuracy, as well as the early warning of extreme disastrous weather.

Key words: lidar, Doppler, coherent wind measurement, wind profile comparison
