lightnings

تعريف lightnings في الإنجليزية الإنجليزية القاموس.: archaic, plural of lightning
lightning: Extremely fast or sudden
lightning: Anything that moves very fast
Nobs, though, was lightning by comparison with the slow thinking beast and dodged his opponent's thrust with ease. Then he raced to the rear of the tremendous thing and seized it by the tail.
lightning: The flash of light caused by the discharge of atmospheric electrical charge
lightning: To produce lightning
I don't know, Father, but believe me, it has been a horrible night — one that I'll never forget. It thundered and lightninged, and I was very hungry.
lightning: Moving at the speed of lightning
lightning: {n} the flash that precedes thunder
Lightning: leven
Lightning: fulgury
Lightning: levin
lightning: - an electrical discharge that results from the buildup of positive and negative charges within a thunderstorm When the buildup becomes strong enough, lightning appears as a "bolt " This flash of light usually occurs within or between, the clouds and the ground When a lightning bolt occurs, the air surrounding its channel is instantaneously heated to as much as 50,000° F, a temperature that is five times that of the sun
lightning: A discharge of atmospheric electricity accompanied by a vivid flash of light During thunderstorms, static electricity builds up within the clouds A positive charge builds in the upper part of the cloud, while a large negative charge builds in the lower portion When the difference between the positive and negative charges becomes great, the electrical charge jumps from one area to another, creating a lightning bolt Most lightning bolts strike from one cloud to another, but they also can strike the ground These bolts occur when positive charges build up on the ground A negative charge called the "faintly luminous streamer" or "leader" flows from the cloud toward the ground Then a positively charged leader, called the return stroke, leaves the ground and runs into the cloud What is seen as a lightning bolt is actually a series of downward-striking leaders and upward-striking return strokes, all taking place in less than a second
lightning: Lightning describes things that happen very quickly or last for only a short time. Driving today demands lightning reflexes. very fast, and often without warning. Visible discharge of electricity when part of the atmosphere acquires enough electrical charge to overcome the resistance of the air. During a thunderstorm, lightning flashes can occur within clouds, between clouds, between clouds and air, or from clouds to the ground. Lightning is usually associated with cumulonimbus clouds (thunderclouds) but also occurs in nimbostratus clouds, in snowstorms and dust storms, and sometimes in the dust and gases emitted by a volcano. A typical lightning flash involves a potential difference between cloud and ground of several hundred million volts. Temperatures in the lightning channel are on the order of 30,000 K (50,000 °F). A cloud-to-ground flash comprises at least two strokes: a pale leader stroke that strikes the ground and a highly luminous return stroke. The leader stroke reaches the ground in about 20 milliseconds; the return stroke reaches the cloud in about 70 microseconds. The thunder associated with lightning is caused by rapid heating of air along the length of the lightning channel. The heated air expands at supersonic speeds. The shock wave decays within a metre or two into a sound wave, which, modified by the intervening air and topography, produces a series of rumbles and claps. See also thunderstorm
lightning: A discharge of atmospheric electricity, accompanied by a vivid flash of light, commonly from one cloud to another, sometimes from a cloud to the earth
lightning: An electrical discharge from a thunderstorm
lightning: the large electric sparks produced in and around thunderclouds
lightning: (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
lightning: 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 thedifference 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
lightning: 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
lightning: a flash of light in the sky produced when electricity passes from one cloud to another or between a cloud and the Earth
lightning: A visible discharge of electricity produced by a thunderstorm
lightning: Very rarely a hazard in Scotland, you will be relieved to hear An approaching electrical storm is normally accompanied by thunder, heavy rain, extra static in the air Leave high and exposed points before it hits
lightning: Any and all of the various forms of visible electrical discharge caused by thunderstorms Severe thunderstorms usually have frequent -- sometimes continuous -- lightning However, some non-severe thunderstorms also contain frequent and vivid electrical displays, while some severe storms are accompanied by little lightning
lightning: The discharge of atmospheric electrical charge itself
lightning: Lightning is the very bright flashes of light in the sky that happen during thunderstorms. One man died when he was struck by lightning Another flash of lightning lit up the cave. thunder and lightning. see also forked lightning
lightning: 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
lightning: A rapid, visible discharge of electricity hotter than the surface of the sun Lightning is caused by the build up of electrical potential between cloud and ground, between clouds, or between clouds and the surrounding air
lightning: a flash of light in the sky caused by the discharge of atmospheric electricity from one cloud to another or between a cloud and the earth
lightning: Usually, any and all of the assorted forms of observable electrical release created by thunderstorms
lightning: Most simply defined as the discharge of electricity from one cloud to another, or from a cloud to the ground
lightning: 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
lightning: {s} of or pertaining to lightning
lightning: visible electrical discharge in the atmosphere, as in: Flashes of lightning illuminated the night sky
lightning: Electrical discharge at high gas pressure, which occurs between thundercloud and soil The electric current in the lightning channel can reach values of 10,000 A The plasma and the neutral gas inside the channel is strongly heated by the current flow This causes a sudden expansion of the lightning channel which can be heard as thunder It could only recently be proved that lightning discharges occur between cloud and ionosphere
