What are some of the best rare natural phenomena that occur on Earth? Ball lightning is an unexplained atmospheric electrical phenomenon. The term refers to reports of luminous, spherical objects that vary from pea-sized to several meters in diameter. Though usually associated with thunderstorms, the phenomenon lasts considerably longer than the split-second flash of a lightning bolt.

The most common type of discharge - lightning inside a single storm cloud, jumping between different charge regions in the cloud. Intracloud lightning is sometimes called sheet lightning because it lights up the sky with a 'sheet' of light.

- The Vincent Black Lightning was essentially a made-to-order motorcycle, designed to race. As such, it was equipped with various go-fast goodies, including rearset foot controls, alloy rims and special lightweight brake backing plates.

Weather Library > Lightning Types and Classifications Ground-to-Cloud Lightning. Ground-to-Cloud Lightning. Ground-to-Cloud lightning (sometimes called Upward-moving lightning) is a discharge between cloud and ground initiated by an upward-moving leader originating from an object on the ground.Ground-to-Cloud lightning strikes are common on tall towers and skyscrapers.his is typically caused by wind blowing the lightning channel sideways during the exposure. The stronger the wind and closer the lightning strike, the more horizontal displacement will exist on the recorded image. Camera movement during the capture of a lightning photograph can also result in the same effect.

What is the science behind how a lightning bolt is hotter than the surface of the sun? How Hot Is Lightning? Technically, lightning is the movement of electrical charges and doesn't have a temperature; however, resistance to the movement of these electrical charges causes the materials that the lightning is passing through to heat up. If an object is a good conductor of electricity, it won't heat up as much as a poor conductor.

- Cloud-to-ground lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts. Objects on the ground generally have a positive charge.

Lightning Lightning is a sudden electrostatic discharge that occurs during a thunderstorm. This discharge occurs between electrically charged regions of a cloud (called intra-cloud lightning or IC), between two clouds (CC lightning), or between a cloud and the ground (CG lightning).

Thunderstorm A thunderstorm, also known as an electrical storm, lightning storm, or thundershower, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Thunderstorms occur in association with a type of cloud known as a cumulonimbus. They are usually accompanied by strong winds, heavy rain, and sometimes snow, sleet, hail, or, in contrast, no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line. Strong or severe thunderstorms, known as supercells, rotate as do cyclones.

Lightning Most lightning occurs within cumulonimbus clouds like these, but it can also be released from wide, layered formations called stratiform clouds. Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. Sheet lightning describes a distant bolt that lights up an entire cloud base. Other visible bolts may appear as bead, ribbon, or rocket lightning.

Lightning rod In a lightning protection system, a lightning rod is a single component of the system. The lightning rod requires a connection to earth to perform its protective function. Lightning rods come in many different forms, including hollow, solid, pointed, rounded, flat strips or even bristle brush-like. The main attribute common to all lightning rods is that they are all made of conductive materials, such as copper and aluminum.

Severe Weather 101 Lightning Types. Lightning strikes the ground, the air, or inside clouds. There are roughly 5 to 10 times as many cloud flashes as there are cloud-to-ground flashes. There are two types of ground flashes: natural (those that occur because of normal electrification in the environment), and artificially initiated or triggered.

Flash Facts About Lightning • During a thunderstorm, each flash of cloud-to-ground lightning is a potential killer. The determining factor on whether a particular flash could be deadly depends on whether a person is in the path of the lightning discharge.

Thunderstorm A thunderstorm, also known as an electrical storm, lightning storm, or thundershower, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder.[1] Thunderstorms occur in association with a type of cloud known as a cumulonimbus. They are usually accompanied by strong winds, heavy rain, and sometimes snow, sleet, hail, or, in contrast, no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line.

Severe Weather 101 The actual diameter of a lightning channel is one-to two inches. Charge distribution in a typical storm cloud [+]. Charge distribution in a typical storm cloud. A typical cloud-to-ground flash is a negative stepped leader that travels downward through the cloud, followed by an upward traveling return stroke.The net effect of this flash is to lower negative charge from the cloud to the ground.riggered lightning goes from ground to cloud, while “natural” lightning is cloud to ground. In 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.

Upper-atmospheric lightning Representation of upper-atmospheric lightning and electrical-discharge phenomena. Upper-atmospheric lightning or ionospheric lightning are terms sometimes used by researchers to refer to a family of short-lived electrical-breakdown phenomena that occur well above the altitudes of normal lightning and storm clouds.

- Sheet Erosion. Sheet erosion is the movement of soil from raindrop splash and runoff water. It typically occurs evenly over a uniform slope and goes unnoticed until most of the productive topsoil has been lost. Deposition of the eroded soil occurs at the bottom of the slope (Figure 3) or in low areas.
