Lightning, Inspiring Beautiful Natural Phenomena Photos.
Lightning – one of the most beautiful natural phenomena, both frightening and awe-inspiring. About 50 times per second in the world comes a lightning strike (more than 4 million times a day).

The Lightning Hunters:
Despite this frequency, the mechanism of occurrence of lightning is not yet fully understood and it is amazing.
Most “lightning” place in the world – a small village in the mountains Kifuka eastern Democratic Republic of Congo. On average, this happens every year 158 lightning strikes per square kilometer.
Lightning – a giant electric spark discharge in the atmosphere, typically occur during an electrical storm, manifesting a bright flash of light and its attendant thunder. The current in a lightning strike reaches 10-300 thousand amperes, voltage – from tens of millions to a billion volts.
Lightning were also detected on Venus, Jupiter, Saturn and Uranus.
Average length zipper – 2.5 km, although some level stretch in the atmosphere at a distance of 20 km.
Most often occurs in the lightning cumulonimbus clouds, then they are called lightning; sometimes lightning is formed in nimbostratus clouds, as well as volcanic eruptions, tornadoes and dust storms.
In 1989 he was discovered by a special kind of lightning – elves, lightning in the upper atmosphere. In 1995, he opened another kind of lightning in the upper atmosphere – jets.
A bolt of lightning is an electrical explosion and in some respects similar to the detonation of the explosive. It causes a shock wave in the immediate vicinity of the danger. The shock wave from a sufficiently powerful lightning at distances up to several meters can be applied destruction, break trees, bruise and injure people even without direct electric shock.
Lightning – a serious threat to human life. The defeat of the human or animal lightning often occurs in open spaces, as the electric current flows along the shortest path “storm cloud-to-ground.” Often lightning strikes in the trees and transformer installation on rail, causing them to fire.
In the body of the victims marked the same pathological changes as in electric shock. The body is usually possible to detect “tags current” point of entry and exit of electricity.
Tall trees – a frequent target for lightning. On relict trees-survivor can easily find multiple scars from lightning – gromoboiny. It is believed that most solitary standing tree struck by lightning, although in some forest areas gromoboiny can be seen on almost every tree. Dry trees lit by lightning. Of trees killed by lightning, sometimes make musical instruments, assigning them unique properties
Lightning is also a very big threat to surface ships in mind that the latter are raised above the surface of the sea and have a lot of sharp items (masts, antennas) that are hubs of the electric field. In times of wooden sailboats with high resistivity body, lightning almost always ended tragically for the ship: the ship burned or destroyed, electric shock people died.
Lightning is the most dangerous for low-flying aircraft or helicopter, as in this case, the aircraft can play the role of conductor of the lightning current from the cloud to the ground. Known that the planes at high altitudes relatively frequently affected by lightning and nevertheless cases of catastrophes for this reason unique.
With powerful ground-based nuclear explosions near the epicenter by the electromagnetic pulse may appear lightning. But unlike these lightning lightning start from the ground and go up.
