你见过巨大的喷气式飞机吗？它们非常罕见，但却非常强大。巨型喷流是本世纪才记录到的一种闪电放电，发生在一些雷暴和地球电离层之间。上图是一架这样的喷气式飞机的中部和顶部，上周由美国波多黎各的闪电和流星相机拍摄到。飞机在不到一秒的时间内飞行了大约70公里。巨型喷流与常规的云对云和云对地闪电大不相同。巨型喷流的底部在外观上与另一种被称为“蓝色喷流”的云对空撞击相似，而顶部则与上层大气中的红色喷流相似。虽然造成巨大喷流的机制和触发因素是一个研究课题，但很明显，喷流减少了地球大气不同部分之间的电荷不平衡。寻找巨型喷气机的一个好方法是在一个清晰的地方观察强大但遥远的雷暴。几乎超空间：随机APOD生成器

Have you ever seen a gigantic jet? They are extremely rare but tremendously powerful. Gigantic jets are a type of lightning discharge documented only this century that occur between some thunderstorms and the Earth's ionosphere high above them. Pictured above is the middle and top of one such jet caught last week by a lightning and meteor camera from Puerto Rico, USA. The jet traversed perhaps 70 kilometers in just under one second. Gigantic jets are much different from regular cloud-to-cloud and cloud-to-ground lightning. The bottoms of gigantic jets appear similar in appearance to another type cloud-to-above strike called blue jets, while the tops appear similar to upper-atmosphere red sprites. Although the mechanism and trigger that causes gigantic jets is a topic of research, it is clear that the jets reduce charge imbalance between different parts of Earth's atmosphere. A good way to look for gigantic jets is to watch a powerful but distant thunderstorm from a clear location. Almost Hyperspace: Random APOD Generator
