Positive lightning is less common than negative lightning and on average makes up less than 5% of all lightning strikes. [8] A bolt from the blue lightning strike which appears to initiate from the clear, but [clarification needed] the turbulent sky above the anvil cloud and drive a bolt of plasma through the cloud directly to the ground. They ...
These flashes usually begin as normal IC lightning flashes before the negative leader exits the cloud and strikes the ground a considerable distance away. [10] [11] Positive clear-air strikes can occur in highly sheared environments where the upper positive charge region becomes horizontally displaced from the precipitation area. [12]
A lightning strike can also create a large Lichtenberg figure in grass surrounding the point struck. These are sometimes found on golf courses or in grassy meadows. [ 12 ] Branching root-shaped " fulgurite " mineral deposits may also be created as sand and soil are fused into glassy tubes by the intense heat of the current.
A lightning strike or lightning bolt is a lightning event in which an electric discharge takes place between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning.

Pockels (1897) estimated lightning current intensity by analyzing lightning flashes in basalt (c. 1900) [12] and studying the left-over magnetic fields caused by lightning. [13] Discoveries about the electrification of the atmosphere via sensitive electrical instruments and ideas on how the Earth's negative charge is maintained were developed ...
