It has been mistaken for UFOs wreaked havoc on homes and eluded rational explanation for centuries.

几个世纪以来，球形闪电被认为是UFO造成的破坏，从而逃脱了寻求合理解释的诉求

But now ball lightning a large mysterious glow that appears during thunderstorms has been explained by scientists for the first time.

但现在，球形闪电这种在雷暴天气出现的，大型而神秘的发光现象，第一次有了科学的解释.

The eerie orb-light glow is created when microwave radiation given off during a lightning strike becomes trapped inside a plasma bubble new research suggests.

新的研究表明，当微波辐射暴露在闪电中时，辐射将被困于等离子体泡内，从而产生一个怪异的球形发光体

Researchers from Zhejiang University in Hangzhou China have proposed that the bright glow of lightning balls is created when microwaves become trapped inside a plasma bubble.

来自中国杭州浙江大学的研究员提出，当微波被困于等离子体泡内，将产生明亮的闪电球

'At the tip of a lightning stroke reaching the ground a relativistic electron bunch can be produced which in turn excites intense microwave radiation' the scientists said in a research paper published in Scientific Reports.

在一篇发表于科学网的研究报告中，科学家称，当雷电的一端到达地面时，会产生一种相对论电子束，这种物质反过来会刺激微波辐射剧烈活动。

'The latter ionizes the local air and the radiation pressure evacuates the resulting plasma forming a spherical plasma bubble that stably traps the radiation.'

后一种物质使局部空气离子化，并且辐射压疏散了所产生的等离子体，从而形成了球形等离子体泡，它可以将辐射稳定地困在内部。

Microwaves trapped inside the continue to generate plasma for a moments to maintain the bright flashes seen during ball lightning they added.

被困在内部的微波辐射在一段时间内会持续生成等离子体，来维持球状闪电发生时肉眼可见的闪光，研究人员补充道。

The fireball eventually fades away as the radiation held within the bubble starts to dissipate - and when microwaves leak out the lightning balls can dramatically explode.

最终，随着等离子体泡内的辐射开始消散，火球也会慢慢消逝---当微波外泄时，球形闪电可能会发生剧烈爆炸。

Ball lightning also known as fireballs and ghost lights have spooked sky-watchers for hundreds of years.

球状闪电也被称为“火球”和“幽灵灯”，数百年来不断引发观测者们的恐慌。

The strange phenomenon can appear in the sky from the size of a golf ball to several metres across and can last between one second and tens of seconds.


这种奇怪的现象可以出现在空中，尺寸从高尔夫球大小到几米不等，并可以持续一秒到几十秒。

The orbs mostly appear during thunderstorms but can also form inside aircraft and closed rooms.

这些球体大多在雷暴天气出现，但也可以在航空器内部和封闭的空间内形成。

And the globe-like structures can decay silently or explode loudly producing rancid odours in their wake.

这种球状体在其尾流中会默默衰减或者爆发出强烈的腐臭气味。

These strange and varying characteristics have presented a 'riddle' to scientists trying to work out their origins.

这些奇特又多样的特征给试图弄清楚它们起源的科学家们带来了一个“谜”。

But now researchers have come up with a theory to explain how the mysterious fireballs form.

不过现在研究人员已经提出了一个理论来解释这种神秘的火球是如何形成的。

Researchers from Zhejiang University in Hangzhou China have proposed that the bright glow of lightning balls is created when microwaves become trapped inside a plasma bubble.

中国杭州的浙江大学研究人员提出，当微波困于等离子体气泡中时，就会产生明亮的电光球。

Ball lightning has been reported to appear during thunderstorms as a glow for centuries.

据报道，球状闪电已经数百年间在雷暴天气出现。

Dad I hope you can see this you were right all along.

爸爸，我希望你能看到你一直都是对的。

Pretty obvious really!!

其实这个迷并不难解，真的！！

I saw ball lightning one stormy night while on hols in Scotland back in the 1980s. Weird stuff. Glad I was well away from it.

我在上世纪80年代到苏格兰度假，在一个风雨交加的夜晚，我看到了球状闪电。这是一个怪异的东西。很高兴我离它很远。

ugly words
Or its the firmament vale slipping off. Expect more of these so called phenomenons.

或者因为它是从天空底部向下滑落。期待能介绍更多这样的现象。

Why does it sometimes appear to follow people or vehicles?

为什么它有时会跟随人或车辆？

Static electric charge..Kind of like when you rub a balloon on your head and you can lift your hair with it like a magnet.. My mother was in the kitchen and a ball lightning popped out of the over (old style gas over you had to light with a match in the 60's).. it floated out of the oven and began following her so she ran out into the dining room and slammed the door shut.. The ball of whatever floated through the door and continued to follow her so she ran from it.. it still followed then disappeared with a pop!.

静电充能……就好比当你用气球磨你的头时，气球能像磁铁一样吸住你的头发。我老妈曾在厨房里看到过球形闪电，它从烤炉里蹦出来(那种六十年代的老式烤炉，要你用火柴点的那种)，它飘过烤炉然后朝我妈飘过去，我妈跑到餐厅然后迅速关上门……结果这玩意竟穿过了门并继续朝她飘去……我妈拼命地跑，它一直跟着……然后……呯的一声，不见了！

So how was your dad?

你爸咋样了？

Makes the electric universe theory even more viable.

让电子宇宙学更靠谱了。

Mr Happiness
I'm glad we finally got that sorted out.

我很高兴这个问题终于被我们解决了。

It could be that. Or the more probable explanation is: highlander

可能是这样。但更可能的解释是: 高地人(注: 苏格兰高地人，通常都很猛)
