- In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground. When the opposite charges build up enough, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we know as lightning.

Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground.

- Thunder
All thunderstorms go through stages of growth, development, electrification and dissipation. Thunderstorms often begin to develop early in the day when the sun heats the air near the ground and pockets of warmer air start to rise in the atmosphere. When these pockets of air reach a certain level in the atmosphere, cumulus clouds start to form. Cont...
Lightning is a giant spark of electricity in the atmosphere or between the atmosphere and the ground. In the initial stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground; however, when the differences in charges becomes too great, this insulating capacity of the ...
Thunder is the sound made by a flash of lightning. As lightning passes through the air it heats the air quickly. This causes the air to expand rapidly and creates the sound wave we hear as thunder. Normally, you can hear thunder about 10 miles from a lightning strike. Since lightning can strike outward 10 miles from a thunderstorm, if you hear thun...
A cloud-to-ground lightning strike starts as a channel of negative charges called a stepped leader makes its path towards the ground. The stepped leader continues towards the ground in a series of steps that are each about 50 to 100 metres in length. The stepped leader can branch out in many directions.

Jan 9, 2022 · The first detailed observations of lightning's emergence inside a cloud have exposed how electric fields grow strong enough to let bolts fly.
2 days ago · Cloud-to-ground lightning is initiated by a preliminary breakdown process within the cloud, typically between the centre region of negative charge and the small positive charge below it. This process creates a channel of partially ionized air—air in which neutral atoms and molecules have been converted to electrically charged ones.
Most CG lightning causes the transfer of electrons (i.e., negative charge) from cloud to ground, and is called negative-polarity lightning. About 9% of CG lightning is positive-polarity, and usually is attached to the thunderstorm anvil (Fig. 15.21) or to the extensive stratiform region of a mesoscale convective system.
