激光测风雷达在航空保障中的典型应用分析

为了研究激光测风雷达在航空气象保障中的监测和预警能力，利用激光雷达的多种模式测量数据，对西宁高原机场2019-04-10一次典型风切变天气演变监测过程进行了详细分析，并与机场现有的测风设备数据、机组报告数据进行了对比。结果表明，激光测风雷达在此次风切变探测过程中，能清楚地探测到风切变的结构、位置、高度和移动方向; 激光测风雷达与自观数据相比，实现提前10min左右的预警; 激光雷达对风切变过程的监测结果与机组报告的结果有较好的一致性。该研究对于民航机场利用激光测风雷达预报风切变天气和保障飞行安全具有一定的参考与指导意义。

Analysis of the typical application of laser wind measurement radar in aviation support

In order to study the monitoring and early warning capabilities of laser wind radar in aviation meteorological support. A typical wind-shear weather evolution at Xining Plateau Airport was analyzed on 2019-04-10, by using multiple modes measure data of laser wind radar, and then compared with the existing data of wind measurement equipment and the data reported by the crew at the airport. The results show that during the wind shear detection process, the laser wind radar can clearly detect the structure, position, height, and movement direction of the wind shear. The laser wind radar can achieve the early warning of wind shear about 10min ahead of the self-view data. The results of the Lidar monitoring of the wind shear process are in good agreement with the results reported by the unit. These conclusions have certain reference and guidance significance for civil aviation airports using laser wind radar to forecast wind shear weather and ensure flight safety.
