最近phys.org的一篇文章讨论了在喜马拉雅山脉上空观测到“红色精灵”闪电的现象。一位Hacker News用户指出,文章没有解释红色是怎么来的(另一位用户猜测可能是激发的氮气)。研究团队开发了一种新方法,利用卫星轨迹和星场分析,将视频片段与实际的闪电事件同步。这使得他们能够精确地将红色精灵与它们起源的闪电放电联系起来。文章提供了Springer上相关研究论文的链接。

For those wondering: There is nothing in the article about why they're red.


Excited nitrogen (N2) in the zone of death?


The article includes a video.

Lacking precise timestamps for detailed analysis, the research team developed an innovative method to synchronize video time using satellite trajectories and star field analysis. This innovative approach allowed them to determine the exact occurrence times of the sprites and link them to their parent lightning discharges.
