摘要
文章以永暑机场单站的K/XDD01型机场雷电监测定位系统为例,分析了其在永暑机场的实际应用,总结了永暑机场发生稳定型降水、一定距离的闪电和过顶雷暴3种常见雷电类型时大气电场强度的变化规律。在临近预报中综合应用LLX06SDN型天气雷达探测资料,归纳得出K/XDD01雷电监测定位系统的优缺点:虽然能够很好地反映雷电发生的大致方位,但定位精度较低,特别是测定距离较为离散;对处于发展状态的雷暴云体监控预警能力突出;对远距离的弱放电及近距离雷电监测能力较弱;由于方位测定方面的设计缺陷,存在0°、90°、180°及270°四个方位上发的识别盲区。并结合工作实际,对K/XDD01型机场雷电监测定位系统的未来使用进行了展望。
This paper takes the K/XDD01 type lightning monitoring and positioning system of Yongshu Airport as an example to analyze its practical application in Yongshu Airport.Summarized the changes in atmospheric electric field intensity during three common types of lightning at Yongshu Airport:stable precipitation,lightning at a certain distance,and overhead thunderstorms.Combined with the comprehensive application of nowcasting and LLX06SDN-type weather radar detection data,the advantages and disadvantages of K/XDD01 lightning monitoring and positioning system are summarized.Although it can reflect the approximate direction of lightning occurrence well,the positioning accuracy is low,especially the measurement distance is relatively discrete.Outstanding monitoring and early warning capabilities for thunderstorm clouds in a developing state.Weak monitoring ability for weak discharge at long distances and lightning at close distances.Due to design flaws in azimuth determination,there are recognition blind spots in four directions:0°,90°,180°and 270°.Combined with practical work,the future use of the K/XDD01 airport lightning monitoring and positioning system is discussed.
