The paper questions what exactly lightning is and what makes the light actually appear, and presents the hypothesis that lightning is an electrical charge that moved from the storm to the ground. The paper goes on to explain that lightning is a release of atmospheric electricity which is brought about by a buildup of conflicting charges within a cloud, and the consequence is a rapid discharge of electricity which results in a distinct bright flash. The paper relates that lightning can be positively charged, negatively charged or both, and it does not move strictly from the storm to the land; it can travel from a cloud to the ground, from the land back up to a cloud and even from cloud to cloud.
From the Paper:"Lightning is a conduit of negative charge, known as a stepped leader that crisscross down in approximately fifty yard fragments in a forked outline. This step leader cannot be seen by the human eye. Lightning discharges to the ground quicker than a person can blink their eyes. As it gets close to the ground, the negatively charged step leader becomes attracted to a positively charged conduit that is reaching up. This is called at a streamer and is usually by way of something tall. When the streamer and the oppositely charged leader connect, a potent electrical current commences flooding. A come back stroke of bright light moves about 60,000 miles per second back in the direction of the cloud. A burst is made up of one or possibly as many as twenty come back strokes. People see the flash when the development quickly duplicates itself numerous times along the same pathway. The real breadth of a lightning channel is about a couple inches (About Lightning, 2010).
"When a stepped leader gets near the land, the occurrence of opposite charges on the land augments the power of the electric field. The electric field is heaviest on ground linked things whose tops are nearest to the bottom of the thundercloud. If the electric field is powerful in a sufficient amount, a conductive release can expand from these points."
