This program calculate the distance between you and the lightning by using an easy to use interface.

It will show the distanse in meter or feet, and a history of the 5 last distances will give you an indication of the movement of the lightning.

Science of Lightning:

Lightning is an atmospheric electrostatic discharge (spark) accompanied by thunder, which typically occurs during thunderstorms,and sometimes during volcanic eruptions or dust storms.

From this discharge of atmospheric electricity, a leader of a bolt of lightning can travel at speeds of 220,000 km/h (140,000 mph), and can reach temperatures approaching 30,000 °C (54,000 °F), hot enough to fuse silica sand into glass channels known as fulgurites which are normally hollow and can extend some distance into the ground. 

There are some 16 million lightning storms in the world every year. Lightning causes ionisation in the air through which it travels, leading to the formation of nitric oxide and ultimately, nitric acid, of benefit to plant life below.

Lightning can also occur within the ash clouds from volcanic eruptions, or can be caused by violent forest fires which generate sufficient dust to create a static charge.

How lightning initially forms is still a matter of debate: Scientists have studied root causes ranging from atmospheric perturbations (wind, humidity, friction, and atmospheric pressure) to the impact of solar wind and accumulation of charged solar particles. Ice inside a cloud is thought to be a key element in lightning development, and may cause a forcible separation of positive and negative charges within the cloud, thus assisting in the formation of lightning.

The irrational fear of lightning (and thunder) is astraphobia. The study or science of lightning is called fulminology, and someone who studies lightning is referred to as a fulminologist.

这个程序计算通过一个易于使用的界面和闪电之间的距离。

它会显示distanse的米或英尺，最后5距离历史会给你一个指示闪电的运动。

闪电科学：

闪电是大气中的静电放电（火花）伴随着雷声，这通常发生在雷暴期间，有时在火山爆发或沙尘暴。

一道闪电的领导者可以从这个排放大气电学，出行220,000公里/小时（140,000英里）的速度，并能达到温度接​​近30,000°C（54,000°F），热到足以熔化硅砂到玻璃渠道通常是中空的，可以延长一段距离到地面的闪电熔岩。

有大约16万闪电风暴在世界上每年。闪电引起电离，通过它行进在空气中，导致一氧化氮的形成，最终，硝酸，有利于下面的植物生命。

闪电也可以发生在从火山喷发的火山灰云，或可引起猛烈的森林大火产生足够的灰尘创建一个静态电荷。

如何防雷初步形成仍是一个有争议的问题：科学家们研究的根源，从大气扰动（风力，湿度，摩擦，和大气压力）带电太阳粒子的太阳风和积累的影响。冰云内部被认为是闪电发展的一个关键因素，可能会导致在云内的正电荷和负电荷的强制分离，从而协助闪电的形成。

非理性的恐惧闪电和雷声是astraphobia。闪电的研究或科学的称为fulminology，研究雷电的人谁被称为作为fulminologist。</div> <div class="show-more-end">
