It used to be mistaken for UFOs, for centuries without reasonable explanation. But now, Chinese scientists have photographed for the first time in ball lightning in a thunderstorm weather videos.
Researchers at the Lanzhou Northwest Normal University in Qinghai province, in a thunderstorm when you draw a map of radiation accident record of the elusive glow ball. A ball of light rising from the ground, lightning, through 15 meters in the ground, and then disappears. Researchers say it has a diameter of about 5 meters, only appeared in less than 2 seconds. And it happened at the 2012 storm video spectra, is considered by far the nature of ball lightning scientific record for the first time.
This study details published in a recent issue of the physics review letters on, confirm the real existence of ball lightning, and provided important clues for ball lightning.
Ball lightning is cloud to ground lightning, steady glow during horizontal movement. Very early on he was seen ball lightning, but because of its rarity, nobody shooting record to this phenomenon.
The Lanzhou Northwest Normal University researchers using spectral devices record ball lightning, which can identify form a major element of ball lightning. They found that ball lightning consists of: iron, Silicon, calcium, and soil composition are the same.
In 2000, James-Denise and others have published research report pointed out that ball lightning may be ordinary lightning struck the ground, it has an intense heat, full of silica in soil evaporation.
Background knowledge
Ball lightning
Rolling ball lightning, commonly known as mines, lightning, thunderstorms usually occur under, just a round ball-shaped lightning ball. For many years, scientific community believe that the phenomenon of ball lightning is false, only decades ago acknowledged its truth.
Rumors of hundreds of people have seen ball lightning, but for hundreds of years it was always a difficult mystery. Previous theory believed that microwave radiation, aerosols, oxide of nuclear energy, dark matter, antimatter and black holes may cause ball lightning.
Ball lightning through the cracks of doors, Windows, Chuck, going into them, sometimes it explodes, destroying buildings, causing human or animal casualties. Passing through it along the way, encounter any obstacles, invincible, but could not burn combustible things around. Typically, a ball lightning explosion releases energy, equivalent to about 10 kilograms of TNT as the explosive release of energy, usually charring, ozone or sulfur odor.
In the 40 's, in France in the small town, 3 soldiers sheltering from the rain under a bodhi tree was killed by lightning, but they still stood, as if nothing happened. After a thunderstorm, pedestrians and talk to them, there was no response, when pedestrians to get in touch with them, it suddenly hit the 3 bodies, and turned it into a pile of ashes.
In the United States, a small town had a strange thing happened: a woman returned home from the market, opening the refrigerator, she put the duck, all become raw meat and cooked food. After the scientists to understand, is ball lightning turned the refrigerator into a furnace, strangely enough fridge not damaged!

它曾经被误认为是不明飞行物，几个世纪以来一直没有合理解释。但如今，我国科学家首次拍到在雷暴天气出现的球状闪电的视频。
兰州西北师范大学的研究人员在青海省一个雷暴天气中绘制辐射地图时，意外记录下这个难以捉摸的发光球。光球从地面升起，变成一道闪电，在地上穿行15米，然后消失。研究人员说，它的直径约5米，只出现了不到2秒钟。这场发生在2012年的风暴的视频和光谱，被认为是迄今为止自然界球状闪电的首次科学记录。
这项研究详细内容发表在近期出版的《物理学评论快报》上，证实了球状闪电的真实存在性，并提供了球状闪电如何存在的重要线索。
球状闪电是云层至地面的闪电，在持续发光期间水平移动。很早就有人目击球状闪电，但是由于其罕见性，没有人拍摄记录到这一现象。
此次兰州西北师范大学研究人员使用光谱设备记录了球状闪电，从而能够识别构成球状闪电的主要元素。他们发现球状闪电中包含：铁、硅、钙，这与土壤主要成分相同。
2000年，詹姆斯-迪尼斯等人曾发表研究报告指出，球状闪电很可能是击在地面上的普通闪电，它具有巨大的热量，完全可以将土壤中的二氧化硅蒸发。
背景知识
球状闪电
球状闪电俗称滚地雷，闪电的一种，通常都在雷暴之下发生，就是一个呈圆球形的闪电球。多少年来，科学界都认为球状闪电是子虚乌有的现象，直到几十年前才承认它的真实性。
传闻有数百人看到过球状闪电，但是数百年来它始终是一个难解之谜。以前的理论认为，微波辐射、氧化浮质、核能、暗物质、反物质和黑洞都有可能引起球状闪电。
球状闪电能穿过门、窗的缝隙、登堂入室、钻进人家，它有时发生爆炸，毁坏建筑物，造成人畜伤亡。它在行经的沿途，遇到任何障碍物时无坚不摧，却又不烧坏周围的可燃之物。通常，一个球状闪电爆炸时释放出的能量，约相当于10公斤TNT炸药爆炸时放出的能量，一般会留下烧焦、硫磺或臭氧的气味。
上世纪40年代，在法国的小城镇里，有3个士兵在一棵菩提树下躲雨时被雷击毙了，但他们仍然站着，像没事一样。雷雨之后，行人跟他们说话，却不见回应，当行人去接触他们时，3具尸体顿时倒地，化成了一堆灰烬。
在美国的一个小城里曾发生了一件怪事：一位主妇从市场回到家里，打开电冰箱一看，她放进去的生鸭、生肉全都变成了熟食品。后经科学家的研究才明白，是球状闪电把冰箱变成了电炉，奇怪的是冰箱没有损坏！
