For some people, lightning is frightening. But, for the other people this natural electric is a beauty of nature that very adorable as well as harmful. To avoid the dangerous effects of lighining, you should understand what the lightning is and how the occurrence of lightning. The Lightning is formed by some wind updrafts and downdrafts that take place in the atmosphere, create a charging mechanism that separates electric charges, leaving negative charge at the bottom and positive charge at the top of the cloud.

As charge at the bottom of the cloud keeps growing, the potential difference between cloud and ground, which is positively charged, grows as well. This process will continue until air breakdown occurs.

The way in which a cloud-to-ground flash develops involves a stepped leader that starts traveling downwards following a preliminary breakdown at the bottom of the cloud.

It is important to highlight that the terminating point on the ground is not decided until the downward leader is some tens of meters above the ground plane and that it will be attached to one of the growing upward streamers from elevated objects such as trees, chimneys, power lines, and communication facilities
