Lightning is a discharge of electricity. A single stroke of lightning can heat the air around it to 30,000°C (54,000°F)! This extreme heating causes the air to expand explosively fast. The expansion creates a shock wave that turns into a booming sound wave, known as thunder.
What is the scientific explanation of lightning?
In the initial stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground; however, when the differences in charges becomes too great, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we.
Does lightning come from ground or sky?
Cloud-to-ground (CG) 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 under a typical thunderstorm.
How does lightning give light?
Lightning is visible as a flash of light because of both incandescence (due to its high temperature it glows blue-white) and luminescence (excitation of nitrogen gas in the atmosphere). The distinctive blue-white color of lightning is caused by light emitted as the electrons drop back to their original energy states.
Does lightning touch the ground every time?
Does lightning strike from the sky down, or the ground up? The answer is both. 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.
Can fire Turn lightning?
Wildfires can create their own weather systems that can produce lightning, hail, and tornadoes. GRAND JUNCTION, Colo. There’s nothing too unusual about that in the summertime, but this lightning was triggered by a very unusual thunderstorm – a Pyrocumulonimbus or fire thunderstorm.
Can lightning strike a house?
Stay indoors and avoid travel if possible. This is because lightning can travel through a building’s plumbing and metal pipes.
What attracts lightning to a person?
Myth: Structures with metal, or metal on the body (jewelry, cell phones,Mp3 players, watches, etc), attract lightning. Fact: Height, pointy shape, and isolation are the dominant factors controlling where a lightning bolt will strike. The presence of metal makes absolutely no difference on where lightning strikes.
Why is the lightning green?
The colder the lightning, the closer the color would be to the far end of the spectrum. The most unusual and alarming lighting color is green. Green lighting indicates that a tornado might be on its way. This phenomena occurs later in the day, when the sun gets closer to the horizon.
What color lightning is the strongest?
White – this is by far one of the most dangerous color of lightning due to the fact that this type of lightning is the hottest. This color can indicate a low concentration of moisture in the air as well as a high concentration of dust in the air.
Is lightning blue or white?
Lightning comes in every color of the rainbow (Red, Yellow, Green, Cyan, Blue, and Violet, to name a few). It’s almost always white, but often it’s tinged with another color around the edges. The three most common colors, aside from white, are blue, yellow, and violet.
What comes first thunder or lightning?
If we are watching the sky, we see the lightning before we hear the thunder. That is because light travels much faster than sound waves. It takes approximately 5 seconds for the sound to travel 1 mile. If the thunder follows the lightning almost instantly, you know the lightning is too close for comfort!.
Can thunder hurt you?
What is there to be scared of? Most storms are harmless, even soothing to some, and nurturing to plants and wildlife. Thunder can’t hurt us, of course, but lightning strikes can be deadly. Still, lightning strikes are deadly, which is why you should go indoors when you hear thunder.
Can lightning power a city?
There is so much power in a thunderstorm. Some places in the world are renown for the sheer number of lightning strikes they get a year. One of these places is Tampa Bay, Florida. This lightning city could theoretically harness the incredible power of lightning to power their city.
What are the 3 types of lightning?
There are three common types of lightning: cloud to ground, cloud to cloud and cloud to air. Cloud to ground lightning is the most dangerous. The ground is mainly consisted of positively charged particles while the bottom of violent storm clouds have negative charged particles.
Can lightning strike the same place twice?
Myth: Lightning never strikes in one place twice. Fact: Actually, lightning can, and often does, strike the same place repeatedly — especially if it’s a tall and isolated object. For example, the Empire State Building is hit about 25 times per year . 5.
Which is hotter lightning or the sun?
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).
What is lightning made of?
Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges.
What happens when thunder hits water?
Lightning doesn’t strike the ocean as much as land, but when it does,it spreads out over the water, which acts as a conductor. It can hit boats that are nearby, and electrocute fish that are near the surface. If you’re at the beach and hear thunder or see lightning, get out of the water.
