In the most common type of cloud-to-ground lightning (CG), a channel of negative charge, called a stepped leader, will zigzag downward in roughly 50-yard segments in a forked pattern. This stepped leader is invisible to the human eye, and shoots to the ground in less time than it …

2017年12月18日 · Lightning can strike the ground, the air, or inside clouds, but there are roughly 5 to 10 times more cloud flashes than cloud-to-ground flashes. Discover the different types of lightning!

Lightning can occur between opposite charges within the thunderstorm cloud (intra-cloud lightning) or between opposite charges in the cloud and on the ground (cloud-to-ground lightning). Lightning is one of the oldest observed natural phenomena on earth.

2025年1月19日 · Lightning is usually associated with cumulonimbus clouds (thunderclouds), but it also occurs in stratiform clouds (layered clouds with a large horizontal extent), in snowstorms and dust storms, and sometimes in the dust and gases emitted by erupting volcanoes.

There are two main types of lighting: intra-cloud lightning and cloud-to-ground lightning. Intra-cloud lightning is an electrical discharge between oppositely charged areas within the thunderstorm cloud. Cloud-to-ground lightning is a discharge between opposite charges in the cloud and on the ground. Cloud-to-ground lightning can either occur ...

2024年4月18日 · Depending on the lightning cloud, its appearance, surrounding weather, and other atmospheric criteria, some of the most common flashing lightning to be aware of include: Intra-Cloud (Sheet Lightning) Cloud To Ground; Cloud …

Cloud-to-ground lightning is divided into two different types of flashes depending on the charge in the cloud where the lightning originates. Thunder. Thunder is the sound made by a flash of lightning. As lightning passes through the air it heats the air quickly. This causes the air to expand rapidly and creates the sound wave we hear as thunder.

2023年4月5日 · The Lightning Process: Keeping in Step. Tall objects, such as trees and skyscrapers, are commonly struck by lightning. Mountains also make good targets. This is because their tops are closer to the base of the storm cloud. Remember, the atmosphere is a good electrical insulator.

Cloud-to-ground lightning is the most damaging and dangerous form of lightning. Although not the most common type, it is the one which is best understood. Most flashes originate near the lower-negative charge center and deliver negative charge to Earth. However, an appreciable minority of flashes carry positive charge to Earth.

Intra-Cloud: The most common type of lightning. It happens completely inside the cloud, jumping between different charge regions in the cloud. Intra-cloud lightning is sometimes called sheet lightning because it lights up the sky with a 'sheet' of light. Cloud to Cloud: Lightning that occurs between two or more separate clouds.
