| 摘 要： | 本文利用福卫二号卫星（FORMOSAT-2）搭载的高空大气闪电影像仪（Imager of Sprites and Upper Atmospheric Lightnings, ISUAL）于2004～2015年期间获得的数据,分析了青藏高原南麓地区（22°～30°N, 86°～98°E）观测到的多例红色精灵事件。通过与全球闪电定位网（World Wide Lightning Location Network,WWLLN）的观测资料进行对比,在分析了17次个例后发现对于大部分红色精灵事件,ISUAL给出的定位效果较好,与WWLLN的闪电定位结果偏差一般小于50 km,这与在北美及其邻近地区得到的结果一致。在此基础上,我们结合风云二号卫星的云顶亮温数据分析了青藏高原南麓地区红色精灵的母体雷暴特征,发现在青藏高原南麓地区除了中尺度对流系统外,小尺度对流系统也是这个地区产生红色精灵的主要天气系统。

| Abstract: | In this paper, the authors examined the sprite phenomenon over the southern Tibetan Plateau (22°-30°N, 86°-98°E) by comparing the lightning detection data from the World-Wide Lightning Location Network (WWLLN) and observations from the Imager of Sprites and Upper Atmospheric Lightning (ISUAL) instrument aboard the FORMOSAT-2 satellite during 2004-2015. It was found that most of the location accuracy of ISUAL was sound after analysis of 17 samples, and the deviations from WWLLN were ＜ 50 km. It was consistent with the results obtained in North America and its vicinity. Based on these results, the authors analyzed the characteristics of the parent lightning strokes of the sprites combined with the cloud-top brightness temperature data from the FY 2 satellite. The authors found that sprites over the southern Tibetan Plateau formed not only from mesoscale convective systems, but also from smaller-scale convective systems. |
