How Does Lightning Form from the Sky?

Lightning do often occurs during stormy weather conditions. Countries under tropical regions often experience heavy rainfalls accompanied by lightning and thunderstorms.

But, how does lightning really form?

Before rain starts to fall, try and observe the behavior of the clouds. You will observe that a group of dark clouds will suddenly overlap the white clouds making your surrounding slightly dim. This will then be followed by some roaring loud thunder and flashes of lightning before the rain starts to fall.

To explain how lightning exactly occurs, those dark clouds are negatively charged or composed of highly charged electrons. Just like a magnet where its negative side is attracted to the positive side, the clouds with negative charges are attracted to the clouds with positive charges. Another instance is that negatives charges in the clouds can also be attracted with positive charges on the ground.

The most common and best understood form of lightning is known as the "Cloud-to-Ground" lightning. Due to its behavior where it often strikes right on the surface of the Earth, this had allowed scientists to conduct researches and studies about lightning. As a result, scientists are able to measure the power of lightning through voltage-measuring instruments. Other than the voltage, they were able to discover that this form of lightning occurs when positive charges from the ground attracts the negatively charged electrons from the clouds.

As a result, lightning occurs when both the positive and negative charges collide.

The second form of lightning that can also be observed from the sky is the "Cloud-to-Cloud" lightning. This is a form of lightning that occurs from the discharge of a negatively charged cloud into another positively charged cloud. There are two different type of occurrences when a cloud-to-cloud lightning occurs. First is known as the "inter-cloud lighting" where the discharge occurs between two separate clouds. Second is when the discharge occurs within one of the two clouds which is referred as "intra-cloud lightning".

A third form of lightning which has been recently discovered by the scientists is known as the "Dark Lightning". It is created by thunderstorm which produces a high form of energy-radiation. With the advancement of our technology, scientists can now observe on their sophisticated instruments the terrestrial-gamma rays that flashes out from the discharge of the thunderclouds. They even found out that dark lightning flashes at a faster speed than the normal type of lightning.

Beware Lighting Strike Can be Deadly


Most people think that once a certain person was hit by a lightning, he is surely dead. This is completely a wrong notion because basing from all previous incidents, the majority of people that has been struck by lightning have survive. They did survive but they had suffered long-lasting neurological damage. Thus, it is still very dangerous to be hit by a lightning even though upon knowing that you have high chances of survival.

Lightning is a very unpredictable force of nature that you will never know when it suddenly strikes you down. The best way to avoid getting hit by a lightning is simply to stay indoor during thunderstorm.
