What Is Lightning Lightning Facts And Safety Tips Learn how thunderstorms produce lightning by separating electric charges and generating electric fields within and below the cloud. see how lightning develops between the cloud and the ground with a stepped leader and a streamer. Lightning occurs when regions of excess positive and negative charge develop within the cloud. typically, there is a large volume of positive charge in the upper regions of the cloud, a large negative charge in the centre, and a small positive charge in the lower regions. these charges reside on water drops, ice particles, or both.
How Lightning Forms Hubpages Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type. Lightning is a large scale natural spark discharge that occurs within the atmosphere or between the atmosphere and the earth’s surface. on discharge, a highly electrically conductive plasma channel is created within the air, and when current flows within this channel, it rapidly heats the air up to about 25,000°c. the lightning channel is an example of terrestrial plasma in action. Learn how thunderstorms develop and how lightning forms as a result of the charge separation in the cloud and the ground. find out how to stay safe from lightning and how to measure its distance and sound. If we are watching the sky, we see the lightning before we hear the thunder. that is because light travels much faster than sound waves. we can estimate the distance of the lightning by counting how many seconds it takes until we hear the thunder. it takes approximately 5 seconds for the sound to travel 1 mile.
