How lightning occurs diagram
WebExplain how lightning takes place? Answer: During the development of a thunderstorm, the air currents move upwards while the water droplets move downwards. These vigorous movements of air currents cause separation of charges. The positive charges collect near the upper edges of the clouds and the negative charges accumulate near the lower edges. Web9 nov. 2024 · This form of lightning occurs when the electrical discharge occurs between the bottom of the cloud and objects on the surface of the ground. Usually, the negatively charged bottom half of the cloud is responsible for the surface of the ground below it becoming charged with positive ions.

Around the world it’s estimated that there are as many as 8 million lightning strikes per day, and around 44 strikes per second are recorded at any one time.
WebLightning Research Laboratory (UF) Weblightning strikes is currently on the increase globally. The magnitude of lightning discharges around the world have been measured from 2000A to more than 200kA, with rise times to peak current of less than 10µs. The variation in magnitude and rise times follows the ‘log-normal’ distribution typical of many natural phenomena.
WebCloud-to-cloud lightning is the discharge between areas of cloud without the discharge channel reaching the ground. For most of the time, it occurs between oppositely charged portions of the same cloud but sometimes it takes place between two separate clouds. Since the discharge channel of cloud-to-cloud lightning may be obscured by the cloud ... WebWhen the air can no longer withstand the force of the electricity, it discharges, and lightning occurs. The positive and negative charges are attracted to each other and discharge in the air. The lightning that occurs in clouds or between thunderclouds is cloud discharge, and the lightning that occurs between clouds and the earth is so-called ...
