Cloud-to-Cloud Strikes

Inter-cloud or "cloud-to-cloud" lightning takes place between oppositely charged areas in two different clouds. The positive and negative charges speed toward each other, completing an electrical circuit that bridges the gap of clear air between the clouds. The nature of these flashes is not very well understood.
