When there is thunder, why is there a cloud of light in the clouds?

That's lightning. Here's the explanation.

In thunderstorm clouds, air currents generate static electricity due to the friction and decomposition of water molecules. There are two types of electricity. One is the positive charge with the positively charged particles, and the other is the negative charge with the negatively charged particles.

Positive and negative charges attract each other, like magnets. The positive charge is at the upper end of the cloud, and the negative charge attracts the positive charge on the ground at the lower end of the cloud. The air between the clouds and the ground is both an insulator that prevents the current of the charge at the poles from passing through.

When the charge in the thundercloud and the charge on the ground become strong enough, the two parts of the charge will break through the air barrier and come into contact to form a strong current, and the positive charge and the negative charge will come into contact. When these opposite-sex charges meet, a neutralizing effect (discharge) occursThe intense neutralization of the charge emits a large amount of light and heat, and these emitted light forms [lightning].

Most lightning bolts are connected twice. The first time it is called a pilot flash, it is an invisible air called a leader, and it goes down to the place close to the ground. This stream of live air acts like a wire, creating a path for the second current.

The moment the lead approaches the ground, a reconnect current jumps up along the path, and the flash produced by the reconnect is what we normally see as lightning.

When thunder, the positive and negative electrostatic ions in the clouds collide and produce a short-circuit fire, which is reflected from the clouds to the ground, and the effect is seen like a flash of clouds.

Thunder is a natural phenomenon. Before thunder, the water vapor (clouds) in the air move violently, and the clouds and fogs ionize due to intense friction, that is, positive and negative static electricity is generated. A single positive or negative static electricity does not thunder.

And as soon as they collide and the ionized electrons are neutralized, they release a huge fire, and a loud sound, which is what people hear about thunder.

The fire, resulting from the collision of the ionosphere, travels at the speed of light at 299792458 meters per second. Therefore, it is common to see the light cluster first and then hear the thunder. This is because the speed at which sound travels through the air is only about 340 meters per second, which is much slower than the speed of light.

If, during thunder, light and sound are seen and heard almost simultaneously, it is a very dangerous environment, indicating that the thunder is nearby.

When dust, ice crystals and other substances in the air roll in the clouds, they go through some complex processes to make these substances have a positive charge and a negative charge respectively. As a result of the movement, a heavier substance with the same charge will reach the lower part of the cloud (usually a negative charge), and a lighter mass substance with the same charge will reach the upper part of the cloud (usually a positive charge). In this way, the convergence of homogeneous charges forms some charged centers, which are formed when the air between the charged centers of the opposite sex is broken down by its strong electric field"Inter-cloud discharge"(i.e. lightning).

When the negatively charged cloud is close to the ground, the protrusions and metals on the ground will be induced to have a positive charge, and with the gradual enhancement of the electric field, the thundercloud will form a downward leader downward, and the objects on the ground will form an upward flash, and the two will meet to form a discharge to the ground. This can easily cause lightning disasters.

Thunder and lightning are formed during atmospheric motion, which is caused by the violent frictional electricity generated during atmospheric motion and the cutting of magnetic field lines by clouds.

The most common shape of lightning is dendritic, in addition to balls, sheets, bands. The forms of lightning include cloudy lightning, inter-cloud lightning, and cloud-to-ground lightning. When lightning strikes between clouds, the friction between clouds forms thunder.

It is produced by the collision of positively charged clouds and negatively charged clouds, respectively.

The charge of the clouds in the sky is different, when the negatively charged cloud collides with the positively charged cloud, it is thundered and discharged, and the positive and negative charges are neutralized.

Ball lightning.. It's very rare. A natural phenomenon.

The electricity is high.

It's not ball lightning, you can't see it at all, you have to be closer to the clouds, and the height is not invisible. And the movement of ball lightning is not what you describe.

It's ball lightning. The shapes of lightning are divided into snake lightning, tree lightning, and ball lightning.

Personally, I think there are two possibilities:

1. Ball lightning. The causes of this lightning are complex, and they are very harmful and penetrating, and can penetrate walls and enter the room. However, this type of lightning is relatively rare;

2. Projection of a ground searchlight on clouds.

In favor of the view upstairs, I have long heard of ball lightning. I haven't been lucky enough to see it, but I actually let you see it, you can go to the encyclopedia to check it, and the explanation is very detailed.

Are you looking forward to me saying that it is a UFO, you have to believe in the existence of miracles, you may see that it is really a UFO, and it is not impossible to say that the searchlight is true!

It is recommended that you watch Liu Cixin's sci-fi ** "Ball Lightning", and after watching it, I believe you will have a deeper understanding of ball lightning.

Ball lightning is so rare, I don't think it could be his, a relative of mine used to see it when I was a child, I haven't seen it yet, I don't know if I can see it.

I think it should be an abominable searchlight.

I also think it's ball lightning. Ball lightning is indeed rare.

Why do you see lightning first and then hear thunder?

Lightning is light, and the speed at which light travels in the air is 299,792,458 m s, generally 300,000 km h; Thunder is sound, the sound in the air is 340 meters and seconds, and the speed of light is much greater than the speed of sound, so thunder first sees lightning and then hears thunder.

The speed of light in air is about 882353 times the speed of sound, and light travels much faster than sound. So we always see lightning and then hear thunder.

Because light travels faster than sound, lightning is seen first, and thunder is heard later.

Because the eyes are in front and the ears are behind,,, hahaha. Just kidding.

The real reason: lightning travels at the speed of light, while thunder travels to our ears at the speed of sound, and the speed of light travels faster than the speed of sound.

I hope you understand.

The speed at which light travels is greater than the speed of sound.

The speed of light is much faster than the speed of sound, and the time difference between the two is as high as the time difference between human recognition.

Lightning and thunder are the result of static electricity interacting in the clouds in the sky. When the positive and negative electricity collide in the clouds, it not only emits a strong and dazzling electric light, but also emits a loud sound, which is what we call thunder. Scientists have measured that the transmission speed of electric light is 300,000 kilometers per second, and the transmission speed of sound in the air is only 340 meters per second, a difference of 880,000 times.

Therefore, when thunder and rain, it is always the electric light of lightning that reaches our eyes first, and then the sound reaches our ears. When the lightning is not far away from us, the difference is not very large, and if the lightning is far away from us, then it will be some time before we can hear the thunder.

Because the eyes are in front and the ears are behind.

Lightning is a natural discharge phenomenon. In summer, there are many clouds in the high sky that are constantly moving, and the clouds are staggered and rubbing against each other, thus generating a large number of electric charges and forming an electric field. Since the same charge repels each other, the positive and negative charges are concentrated at each end of the cloud.

When the electricity carried by the cumulus cloud reaches a certain level, it will pass through the air and discharge, neutralizing the two charges and generating sparks. This is the phenomenon of lightning. Because of the uneven resistance of the air, the shape of the electric advance is mostly zigzag, forming a band of light like a tree branch, which is called lightning.

And the discharge causes the air to vibrate and make a sound, which is thunder. Sound travels about 340 meters per second in the air, while light travels almost 300,000 kilometers per second in the air. So we always see lightning first and then hear thunder.

Sometimes, because the discharge cloud is too far away from us, or the sound is not loud enough, and the energy of the sound is less and less when it travels through the air, so we only see lightning and do not hear thunder. Most of the lightning occurs at low latitudes, such as Indonesia, central Africa, southern Mexico, Panama, and central Brazil. The place with the most thunderstorms in the world is Bogor City, Indonesia, which is known for its 322 days of lightning and lightning during the year"The thunder capital of the world"called.

From the comparison of the speed of light and the speed of sound, it is clear that lightning is seen first, and thunder is heard. You know, you can circle the earth seven and a half times in just one second! Lightning is spectacular, but it can also be harmful.

A single lightning bolt is equivalent to about 600 kilowatts of electricity, and it can destroy houses and cause forest fires. The destruction of high-voltage transmission lines has brought a lot of inconvenience to people's lives. Avoiding lightning hazards is as simple as directing lightning underground through electrical wiring.

As early as more than 1,000 years ago, the Chinese invented many ingenious lightning protection devices, such as in traditional buildings, the eaves of the roof are often decorated with dragons, and the dragon's mouth spits out a metal tongue to the sky. The base of the tongue is connected to a wire that leads to the ground. When lightning strikes the house, the electric current travels from the dragon's tongue along the wire to the ground.

For thousands of years, after many ups and downs, lightning and thunder, it is such a simple, practical and beautiful device that has protected one ancient and precious building after another! Lightning is a natural phenomenon that often occurs in nature, and because the speed of light is much greater than the speed of sound, we often see lightning first and then hear thunder. Lightning can bring different degrees of harm to people, so lightning rods came into being.

If you can see lightning but you can't hear thunder, it means that you are far away from the thunder, and if it doesn't rain, it means that you are far away from the clouds.

Thunder and rain are not necessarily related to thunder, and rain is a phenomenon of electrical discharge, and rain is formed by the condensation of water vapor into small raindrops.
