Gigantic Jet Lightning over India

Explanation: Yes, but can your lightning bolt do this? While flying from Munich to Singapore earlier this month, an industrious passenger took images of a passing lightning storm and caught something unexpected: gigantic jet lightning. The jet was captured on a single 3.2-second exposure above Bhadrak, India. Although the gigantic jet appears connected to the airplane's wing, it likely started in a more distant thundercloud, and can be seen extending upwards towards Earth's ionosphere. The nature of gigantic jets and their possible association with other types of Transient Luminous Events (TLEs) such as blue jets and red sprites remains an active topic of research.

说明:对了,你见过像这样的闪电吗?本月早些时候,一位勤劳的旅客在从慕尼黑飞往新加坡的途中,拍摄到一场正在发生的雷暴,并捕捉到一些意想不到的现象-巨大的喷流。这道喷流是在拍摄于印度巴德拉克上空的一幅曝光时长为3.2秒的影像中捕捉到的。尽管这道巨大的喷流似乎与飞机的机翼相连,但它很可能是从一片更遥远的雷云发出的,我们可以看到它朝着地球的电离层向上延伸。巨大喷流的本质及它与其他类型的瞬变发光事件(如蓝色喷流和红闪)的可能关联仍然是一个活跃的研究课题。
