The luminous phenomenon accompanying a sudden electrical discharge (see cloud-air lightning, cloud-cloud lightning, cloud-ground lightning and in-cloud lightning).
A sudden visible flash of energy and light caused by electrical discharges during a thunderstorm.
Sudden high-current discharge caused by a planet atmosphere's electrical breakdown.
Discharge of an electric field from a cloud.
Visible discharge of electricity created by thunderstorms.
(abbrev. LTNG) A visible electrical discharge produced by a thunderstorm. The discharge may occur within or between clouds, between the cloud and air, between a cloud and the ground or between the ground and a cloud.
The flash of light accompanying a sudden electrical discharge which takes place from or inside a cloud, or less often from high structures, the ground or mountains. Lightning is caused when the negative charge in the lower part of the cloud and the positive charge in the upper part of the cloud become so great the air within the cloud breaks down to allow an electrical current to flow through it and discharge. The mechanism of charge separation is still highly debated. See also thunder.
A sudden and visible discharge of electricity produced in a thunderstorm, creating a flash of light generated by the flow of electrons between opposite charged parts of a cumulonimbus cloud. This can occur within a cloud, between clouds, from the cloud to air, or from the cloud to the ground. For examples, see heat lightning and ball lightning.
The flash of light that accompanies an electric discharge between two clouds or between a cloud and the earth. It is produced by static electricity built up during a thunderstorm.
Most simply defined as the discharge of electricity from one cloud to another, or from a cloud to the ground.
A natural electric discharge in the atmosphere, usually evidenced by a flash of light produced by such discharge. A lightninig rod attracts the discharge and sends it to the ground. Ben Franklin invented the lightning rod.
A visible discharge of electricity associated with thunderstorms.
abrupt electric discharge from cloud to cloud or from cloud to earth accompanied by the emission of light
the flash of light that accompanies an electric discharge in the atmosphere (or something resembling such a flash); can scintillate for a second or more
The visible flash of light accompanying a large-scale high-voltage natural electric discharge in the atmosphere.
A sudden flash of light generated by the flow of electrons between oppositely charged parts of a cumulonimbus cloud or between the cloud and the ground.
any and all forms of visible electrical discharges produced by thunderstorms.
The electrical discharge from a thunderstorm cloud. Lightning is responsible for more deaths in Florida, by far, than any other weather-related cause.
A visible electrical discharge produced by thunderstorms.
visible bright flash created from the discharge of the current between areas of opposite charges; can form between clouds or from cloud to ground
if a thunderstorm approaches: get off exposed alpine ridges and summits - get as far down the mountain as you can do not stand under a lone tall tree (or small clump of trees), or at the edge of a taller forest get off any body of water (lakes), do not stand on damp ground (swampy areas, ditches) do not stand in shallow caves, or rock scoops in cliffs do not stay in wooden shelters or tents get into forest of uniform height, or into a vehicle if you are caught in a storm: discard large metal objects sit on your dry pack if it is greater than 4" thick; or squat or kneel on ground cover ears with hands
An enormous discharge of electricity in the atmosphere that results when a thunderstorm cloud becomes polarized.
A very positive omen implying a major stroke of good luck coming your way in the near future. Even if the lightning was accompanied by rain and thunder, it is still a positive omen, but positive events will be preceded by a period of anxiety.
A sudden visible flash of energy and light caused by electrical discharges from thunderstorms.
a current of electricity that flows between clouds or between a cloud and the Earth
A visible electrical discharge produced by a thunderstorm from one cloud to another or from cloud to ground. Lightning kills more people in the US than do tornadoes.
Any and all of the various forms of visible electrical discharge caused by thunderstorms. Severe thunderstorms usually have very frequent and sometimes nearly continuous lightning. However, some non-severe thunderstorms also contain frequent and vivid electrical displays, while some severe storms are accompanied by little lightning.
any visible electrical discharge produced by thunderstorms
is a discharge of atmospheric electricity accompanied by a vivid flash of light. During thunderstorms, static electricity builds up in clouds. A positive charge builds in the upper part of the cloud, while a negative charge builds in the lower portion. When the difference between the charges becomes great, the charge jumps from one area to another, creating a lightning bolt. Most lightning bolts strike from one cloud to another but they can also strike the ground. Such bolts occur when positive charges build up on the ground. A negative charge or "leader" flows from the cloud toward the ground and then a positively charged leader (called the return stroke) runs from the ground to the cloud. What appears as a lightning bolt is actually a series of downward and upward strokes, all taking place in less than a second.
An electrical discharge produced by a thunderstorm.
The flash of light which accompanies a static electricity discharge between two clouds or between a cloud and the earth during a thunderstorm.
An electrical discharge from a thunderstorm.
A static electrical discharge between two clouds or between a cloud and the earth accompanied by a flash of light.
The release of static electricity, formed from water molecules rubbing against each other when storm clouds are developing.
Generally, any and all of the various forms of electrical discharge produced by thunderstorms.
Any and all forms of visible electrical discharge produced by a thunderstorm.
(Foudre) Most fire insurance policies make the company liable for all losses caused by lightning, even when no fire occurs. Most policies, however, carry the electrical apparatus clause, which excludes loss caused by artificially generated electrical currents to electrical equipment.
An atmospheric electrical phenomenon associated with thunderstorms; a surge on a system that results from energy being impressed on the system.
Luminous manifestation accompanying a sudden electrical discharge which takes place from or inside a cloud or, less often, from high structures on the ground or from mountains.
A sudden and visible discharge of electricity produced in response to the build up of electrical potential between cloud and ground, between clouds, within a single cloud, or between a cloud and surrounding air.
Discharge of static electricity in the atmosphere, usually between the ground and a storm cloud.
Lightning is an atmospheric discharge of electricity, which usually, but not always, occurs during rain storms, and frequently during volcanic eruptions or dust storms.
