Lightning
, lightning is caused by a natural phenomenon that occurs under clouds or thunderstorms, meteorologists called Nimbus cloud accumulator Barcelona. (Cumulonimbus), which is a cloud that resembles a large chunk mammoth bases of the clouds (bottom) is a height of approximately 2 kilometers and at the cloud top (top edge), it may be as high as 20 km. When the clouds are moving with the wind into the clouds and air currents to flow in fast and furious. Make ice cubes and water droplets in clouds, causing friction and found that positively charged ions usually gathered on a cloud. The negative charge in the base of the cloud negatively charged cloud base may induce the surface of the Earth is "under the shadow" of it has a positive charge. As a result, devises birth The electric field between those charged when the charge has accumulated a lot. The electric field causes a strain of rising beyond durability. Air voltage Cause discharging up at the origin of the lightning discharge may occur between clouds or between a cloud and the earth, which calls this phenomenon the "lightning"
aspect
1. lightning within clouds. The connection anionic, cationic below the top together. Lightning is most often caused
by lightning 2. From cloud to cloud as the first one. The negative charge in the cloud to cloud more positive ions in one lump
3. lightning from the cloud base to the ground. Or delete lightning Caused by the release of negative ions out of the clouds, so-called lightning negative (negative lightning) and harm to people, animals and things on the floor that would have cut the area under the shade of clouds, rain fiery. because those areas have induced a positive charge
4. lightning from the cloud to the ground. Positive or lightning Caused by the release of positive charge out of the clouds, so-called lightning positive (positive lightning) Lightning additive can operate farther away from the cloud up to 40 kilometers, within one second, often resulting in the conclusion of a thunderstorm. After the rain, and
lightning protection,
lightning protection means. To prevent damage due to lightning, which is the result of mechanical, thermal and electrical effects of lightning often cause damage. A threat to life and property if there is no protection or action to prevent problems.
