The thunder rumbles on a rainy day, and it is particularly clear and loud to hear near me, what s go

The process by which thunder is generated.

Along with the lightning came the rumbling of thunder. As it sounds, thunder can be divided into two types. One is the crisp and loud, like the sound of thunder, which is generally called "explosive thunder"; The other is a dull rumble, which some people call "muffled thunder".

There was also a low, long-lasting rumble, somewhat like the sound of grinding. People often call it "pulling thunder", which is actually a form of stuffy thunder.

The air in the lightning path suddenly and violently heats up, making its temperature as high as 15,000-20,000, thus causing the air to expand dramatically, and the air pressure near the channel can increase to more than 100 atmospheres. This is followed by rapid cooling, the air shrinks rapidly, and the pressure decreases. This sudden expansion and contraction occurs in a short period of a few thousandths of a second, so in the moment of the lightning explosion, a shock wave is generated.

The shock wave travels in all directions at a speed of 5,000 meters per second, and during propagation, its energy quickly decays, while the wavelength gradually increases. Seconds after the lightning strikes, the shock wave evolves into a sound wave, which is what we hear as thunder.

There is also a theory that thunder is the sound produced when **gas occurs**, which is formed due to the decomposition of air and water vapor molecules under the action of high-voltage electric sparks. The sound of thunder is the same as ** sound waves for the first tenths of a second. This wave spreads at a speed of about 5,000 meters per second, and after that, it evolves into an ordinary sound wave.

Thunderbolts, as they are often referred to, are the sounds of cloud-to-ground lightning that are very close to the observer. In this case, the observer hears thunder almost immediately after seeing the lightning; Sometimes thunder is heard at the same time as the lightning. Because the lightning is near the observer, the ** wave it produces has not had time to evolve into ordinary sound waves, so it sounds like ** sound.

If lightning is in the cloud, the thunder is reflected many times in the cloud, and when the ** wave is decomposed, many sound waves of different frequencies are generated, which interfere with each other and make people sound dull, which is the muffled thunder we hear. Generally speaking, a thunderbolt is less loud than a thunderbolt and is not as scary as a thunderbolt.

Pull mill thunder is a long-term muffled thunder. The reason for the prolongation of the thunder is mainly due to the multiple reflections of sound waves in the clouds and the effect of multiple lightning bolts with different heights and distances. In addition, sound waves are reflected when they encounter mountain peaks, buildings, or ground.

Some sound waves are reflected multiple times. It is possible for these multiple reflexes to reach our ears one after the other in a very short interval. At this time, we sounded that the thunder was dull and long, like a grinding.

When thunder strikes, the air vibrates violently, causing a sound.

Rumbling is caused by the different heights of the clouds, and there are multiple layers of clouds, and the sound is repeatedly reflected in the clouds.

The rumbling thunder is a process of gathering electricity, the sound of a thunderbolt is a process of discharge, and a very loud sound is discharging, tearing the air, and the sound made by touching a certain substance does not rule out that it may hit something.

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.

My friend replied that the thunder was so loud that you could hear it very clearly.

Your ears are more sensitive than others.

Thunder is produced by a classic impact in the sky, and the propagation of sound is affected by distance. So you will see lightning first, then thunder, and it will rumble. Comments0 0 Load more Other(1) Latest (1) Dream Life Level 1 2015-09-24 Because in the air Light is transmitted.

One is lightning, but it is high-altitude lightning, and there is no electric light on the ground, only thunder, and the second is that there are airplanes in the sky. Why is there a sudden whining sound in the sky? Why is there a whining sound all of a sudden, it must be thunder, the kind of sound that will only be worn after a day of taking a branch wax, don't be afraid if it's okay.

Especially at night, there is a horizon.

The rain became heavier and heavier, and the sound of "booming" rain and "booming" thunder intertwined, playing a symphony of summer rainstorms. Ten minutes later, the rain was noticeably lighter, and it fell on the leaves, making a rustling sound, and the thunder gradually disappeared, and the surroundings were quiet.

It is because the clouds with positive and negative charges in the sky meet and collide and discharge, and the area is very large, so it is not a boom, but a lot of times, and there is a rumbling sound. When it rains, some of the clouds in the sky have yang electricity and some have yin electricity, and when the two clouds come together, they will discharge electricity, emitting very bright lightning.

Thunder is loud because electricity generates heat when it passes through the air, causing the air to expand rapidly, resulting in a loud noise.

Warm and moist air climbs violently at high altitude, and a strong convection phenomenon occurs, forming cumulonimbus clouds, so there is a weather phenomenon of snow on one side and thunder on the other. There were many air currents in the air that were constantly moving and trembling. Some of these currents run upwards and some downwards in different directions.

The speed is also different, some are fast, some are slow. The movement of the air currents causes some cumulus clouds in the air to rush upwards and some to descend. The friction between clouds and clouds causes clouds to carry different kinds of charges.

Since the same kind of charges are repulsive, the positive and negative charges are concentrated at the opposite ends of the cloud. The faster the air moves, the thicker the clouds, and the more electricity is carried.

Precautions for thundering:

1. When it rains, it is strictly forbidden to stay on the top of the mountain or in the high hill area, and it is also important not to continue to pedal to a high place to watch the rain, not to take shelter under big trees or near telephone poles, nor to walk or stand in an open field, to hide in a low-lying place as soon as possible, or to find a house or dry cave as much as possible to take refuge.

2. During thunderstorms, do not use metal handle umbrellas, take off metal frame glasses, watches, trouser belts, if you are traveling by bicycle to leave the bicycle as soon as possible, you should also stay away from other metal objects, so as not to produce conductivity and lack of chance to be struck by lightning.

3. In thunderstorms, do not go to rivers, rivers, lakes for swimming, boating, fishing, etc.

The sound of wind and rain comes at night, and the flowers fall to know how much.

Thunder is caused by the friction of positive and negative charges between clouds and clouds in the atmosphere to produce violent discharge, produce high temperatures, make the atmosphere expand sharply, and produce a deafening loud sound, which is lightning and thunder.

When atmospheric charges are constantly accumulating in the clouds. If the amount of charge becomes strong enough, lightning will occur. When lightning crosses the sky, it can quickly warm up the air along its path.

The heated air swelled rapidly, and the clumps slammed into all directions as violently as if they were happening. This causes a huge sound wave. Ode to the Shed.

The reason for the loud thunder is that when there is a voltage difference between the positive and negative charges, it will cause an electric shock discharge, and then a strong current will be generated, which will run in the lightning channel, and then thunder and lightning will be formed. When lightning is formed, different weather conditions and environments can affect its sound propagation, resulting in loud sounds.

In an article in the magazine "Scientific American" it was noted that the main determinant of the magnitude of thunder is the speed of the sound waves emitted by the lightning channel, and the speed at which the sound waves travel through the air depends on factors such as the temperature and humidity of the air. The lightning channel will cause the surrounding air to heat up rapidly and turn into gas under the condition of ionization, forming a process similar to **, and the gas produced will spread outward at a rapid speed, forming a strong sound pressure wave, and the sound will be generated.

In addition to this, the sound of thunder is also affected by distance. The time it takes for people to hear thunder is not the time it takes for lightning to hit the ground to make a sound, but the time it takes for the sound to travel through the air to our ears. Therefore, the distance of thunder is directly related to how loud the sound of Bizha Li can be heard, and the sound heard at close range is louder than the sound heard at a distance.

In general, the loud thunder is caused by a powerful sonic boom caused by a lightning discharge. Different environmental and weather conditions affect the propagation and size of sound, and distance is also one of the main factors affecting the sound size. <>

Lightning is a discharge phenomenon in which a strong electric field is formed between various parts of the thunderstorm cloud or between the cloud and the ground due to different charged properties. Due to the narrowness of the lightning channel, too much current passes through it, which makes the air column in the lightning channel burn white hot, and causes the surrounding air to be heated and suddenly expand, and the cloud droplets will also suddenly vaporize and expand due to the high heat, resulting in a loud sound - thunder. The thunder generated inside and between the cloud is high-altitude mine; Thunder generated in cloud-to-ground lightning is called "landing lightning".

The huge current, blazing high temperature and electromagnetic radiation and accompanying shock waves formed by the landing mine all have great destructive power, which is enough to destroy the human body and buildings. For example, at 7:20 on April 25, 1986, in Guanyin Pavilion, Shuangjing, and Low Zhuang Township in Lipu County, Hunan Province, dark clouds were overwhelming, wind and rain were combined, and lightning and thunder were ......With a strong flash, a deafening thunderbolt - a thunderbolt on the ground, affected 3 townships and 6 villages, and suddenly there was chaos, thunder, rain, wind, crying, and shouting mixed together. According to the investigation of the prefectural and county joint investigation teams, 7 people were killed and 10 people were injured by lightning strikes on the spot, including 3 seriously injured.

After the lightning strike** accident, the investigation found that the wires in the houses of residents in this area were installed messily, the wiring position was very low, and 5 of the 7 people who died were struck by lightning under the lighting lights and switches; The room is quite humid before the lightning strike, which creates the conditions for the formation of lightning accidents. Therefore, the installation of wires must meet the requirements, and when lightning, stay away from metal objects that are easy to conduct electricity, and keep the room dry is one of the important measures to prevent lightning strikes.

The damage of lightning to the human body has the direct effect of electric current and overpressure or kinetic effect, as well as the effect of high temperature. When a person is hit by lightning, the current quickly passes through the human body, which can lead to the arrest of heartbeat and breathing, and the lack of oxygen in the brain tissue and death. In addition, lightning strikes produce sparks, which can also cause different degrees of burns.

Lightning injuries can also cause dendritic lightning strikes, epidermal peeling, intracutaneous hemorrhage, and rupture of eardrums or internal organs.
