| 摘 要： | 根据2019年7月20日新疆大部分区域出现局部强对流天气过程,利用ADTD、LLS、WWLLN、风云四号卫星闪电成像仪组产品LMIG、大气电场多源闪电观测资料,对比分析这5种资料在新疆地区的应用情况。结果表明:LLS地闪探测效率最高,LMIG和WWLLN地闪探测效率较低;ADTD、LLS、WWLLN三者定位结果在时间和空间上对应基本一致,仅探测效率有所差别。新疆地区部分LMIG数据存在时间和空间上的偏差,使用前需要利用相关资料进行数据检验。卫星全天空、实时监测,可以弥补新疆南部(简称南疆)地面观测站覆盖不到的区域,两者可互为补充。

| Abstract: | According to the partial severe convective weather in most parts of Xinjiang on July 20, 2019, compared and analyzed these lightning observation data from Active Directory Topology Diagrammer (ADTD), Lightning Location System (LLS), World-wide Lightning Location Network (WWLLN), Fengyun-4A Lightning Mapping Imager Group (LMIG),and atmospheric electric field. The results showed that: the detection efficiency of LLS to cloud to ground (CG) is the higher than that of LMIG and WWLLN; the location results of ADTD, LLS and WWLLN are basically consistent in time and space, but the detection efficiency is different; some LMIG data have deviations in time and space, which need to be checked before using; satellite full sky and real-time monitoring can make up for the areas that cannot be covered by ground observation stations in some areas, and the two can complement each other. In the next step, the fusion of multi-source data will be carried out, lightning monitoring near warning method combined with the atmospheric electric field instrument will be established. |
