No, lightning is a build up of static electricity. The lightning flash is a very short natural electrical discharge between the thunder clouds and the ground, or from cloud to cloud. The route taken by the lightning creates a vacuum, and the roll of thunder sound is the surrounding air crashing back to refill the vacuum.
Lightning is caused by the buildup of electrical charges within a storm cloud. When the charge difference between the cloud and the ground or between two parts of a cloud becomes too great, it discharges as a bolt of lightning.
Lightning is static electricity. It's a buildup of charge, and it is facilitated by charge separation. In that light, it is DC.
Yes. Although the development of these charges is still mostly understood, the buildup of opposite charges in the clouds can create a discharge (lightning) between the cloud and the ground, or the cloud and another cloud. Sometimes the distribution of charges can be seen in a dendritic (forked) pattern of lightning bolts. (see related link)
Inter-cloud lightning!
Sheet lightning is Cloud to Cloud where Lightning is Cloud to Ground.
It's called in-cloud or cloud-to-cloud lightning.
It's called in-cloud or cloud-to-cloud lightning.
The cloud
Lightning is formed with a nimbocumilus cloud.
It's called in-cloud or cloud-to-cloud lightning.
cloud to cloud lightning
It's called in-cloud or cloud-to-cloud lightning.
