2 days ago · Lightning, the visible discharge of electricity that occurs when a region of a cloud acquires an excess electrical charge, either positive or negative, sufficient to break down the resistance of air. It can occur within the cloud, between clouds, between the cloud and the air, or between the cloud and the ground.

Oct 19, 2023 · Lightning is very, very hot—hotter than the surface of the sun. It can reach 28,000 degrees Celsius (50,000 degrees Fahrenheit). Lightning is more likely to strike objects that stick up off of the ground, including people.
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.
Three primary types of lightning are defined by the "starting" and "ending" points of a flash channel. Intra-cloud (IC) or in-cloud lightning occurs within a single thundercloud unit. Cloud-to-cloud (CC) or inter-cloud lightning starts and ends between two different "functional" thundercloud units.
Aug 27, 2024 · Learn how lightning forms as a result of static charges in a rain cloud and how thunder is created by the heated air around it. Find out how to stay safe in a lightning storm and how to observe lightning from space.
