乌鲁木齐机场风切变特征分析及对新跑道建成后风切变告警系统的思考

Analysis of Wind Shear Characteristics at Urumqi Airport and Consideration of Wind Shear Warning System after the Completion of New Runway

本文利用机场AWOS资料、激光测风雷达资料及新疆区域航空器空中报告对2020~2023年新疆空域内航路危险天气事件进行统计,并对风切变进行着重分析,结果表明:1) 风切变是对航路影响最大的危险天气。2) 机场东南大风时风切变强度较强,持续时间长,出现风切变的频数较大。跑道两端风速差越大,风向差越大,水平风切变越强。3) 可利用三条跑道AWOS可实现对机场平面的风切变进行监测和告警,结合激光测风雷达产品,构建时间连续性强、时空分辨率高的机场低空三维风切变监视模型,提供有效的风切变告警产品,对保障机场低空飞行安全来说是有价值的。

In this paper, using AWOS data, laser wind radar data and Xinjiang regional aircraft air report to make statistics on hazardous weather events in Xinjiang airspace during 2020~2023, and focuses on wind shear analysis. The results show that: 1) Wind shear is the hazardous weather with the greatest impact on flight paths. 2) Wind shear is stronger and lasts longer when the airport is windy from the southeast, and the frequency of wind shear is higher. The greater the difference in wind speed between the two ends of the runway, the greater the difference in wind direction, the strong-er the horizontal wind shear. 3) The three runway AWOS can be used to monitor and warn the wind shear in the airport plane, and combined with the laser wind radar products, to construct a three-dimensional wind shear monitoring model with strong time continuity and high spatial and temporal resolution in the low altitude of the airport, and to provide effective wind shear warning products, which is valuable to ensure the safety of low altitude flights in airports.
