When lightning strikes the ground or an object on the ground, the discharge occurs in and along the ground surface (not deep into the ground). This creates a dangerous and potentially deadly ground current near the lightning strike.

Cloud-to-Ground (CG): This is the most recognised type, where lightning strikes the Earth. It is dangerous and can cause significant damage. Intra-Cloud (IC): Lightning that occurs within a single cloud. It is the most common type but often not visible from the ground. Cloud-to-Cloud (CC): Lightning that travels between different clouds.

A lightning strike or lightning bolt is a lightning event in which an electric discharge takes place between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning.

By safely conducting a lightning strike to the ground, a lightning protection system, usually incorporating at least one lightning rod, can greatly reduce the probability of severe property damage.

There are two ways that flashes can strike ground: naturally downward (those that occur because of normal electrification in the environment), and artificially initiated or triggered upward. Artificially initiated lightning is associated with things like very tall structures, rockets and towers.

When lightning strikes a tree or other object, much of the energy travels outward from the strike in and along the ground surface. This is known as the ground current. Anyone outside near a lightning strike is potentially a victim of ground current. In addition, ground current can travel in garage floors with conductive materials.

If a lightning flash is going to strike ground, a channel develops downward toward the surface. When it gets less than roughly a hundred yards of the ground, objects like trees and bushes and buildings start sending up sparks to meet it.

What happens to the ground when lightning strikes it? What tends to happen when lightning strikes ground is that it fuses dirt and clays in to silicas. The result is often a glassy rock (called a fulgurite) in the shape of a convoluted tube.

No, lightning does not always strike the ground. Lighting can occur between clouds (“cloud-to-cloud”) or even inside a cloud (“intra-cloud”). Only about 20% of lightning strikes hit the ground and are known as “cloud-to-ground” lightning.

2024年4月15日 · Lightning causes electric currents along the top of the ground that can be deadly more than 100 feet away. Get inside a safe location; no place outside is safe. Avoid anything that will increase your risk of being struck by lightning, such as being near or under tall trees.
