风廓线雷达部署原则及北京地区应用分析

THE DEPLOYING PRINCIPLE OF WIND PRINCIPLE OF WIND PROFILE RADAR AND APPLICATION ANALYSIS FOR BEIJING AREA

从风廓线雷达的探测原理以及气象、环保、航空等行业的需求出发,借鉴国外风廓线雷达布网经验,讨论了部署的一般原则,主要从地形地貌、天气系统的影响路径以及污染源监测等方面分析了北京地区风廓线雷达部署方案的优势并针对不足提出了建议,主要结论有:(1)风廓线雷达的部署应充分考虑应用目的,并针对不同天气系统的监测和使用领域的差异进行选型;(2)地形地貌、不同移动路径天气系统的权重影响以及对污染物扩散的监测等都是进行风廓线雷达部署的重要参考指标;(3)风廓线雷达局地布网应考虑与全局组网的需求接轨;(4)保持适当数量的机动式风廓线雷达,应对可能出现的异常情况。

By discussing general deploying principles of wind profile radar from the detection mechanism of wind profile radar and demands of the weather, environmental protection, aviation and other industries, refer to the present situation of foreign deployment at the same time.Analyzing the advantages and putting forward the countermeasures of the？ wind profile？ radar？ deployment scheme in Beijing area, in terms of the landscape, the influential path of the weather system and pollution monitoring etc.The following are the main conclusions： I.The deployment of wind profile radar should？ be fully considering the application purpose, aiming at monitoring different weather system and different using fields to make the selection.II.The influence of the Landscape and the mobile path of different weather systems,monitoring the key areas and pollutant diffusion are the important factors that affect the wind profile radar deployment.III.The local wind profile radar deployment also need to consider with the demands of the nationwide network.IV.In response to the abnormal situation occurring, we should maintain proper number of mobile wind profile radar.
