The sound of thunder in the middle of the night is strange, what is the reason for the particularly

The strange sound of thunder in the middle of the night is probably due to the following reasons:

1.In the middle of the night, the temperature is lower and the air is denser, which slows down the propagation of sound waves, resulting in abnormal echoes.

2.During a thunderstorm, a large amount of electric charge is released after the charge of the cloud collides, forming an electric field that causes the air to ionize and make a thunderous sound. Due to the uneven distribution of charges in the clouds, thunder can change in tone, timbre, and loudness.

3.Thunder is accompanied by heavy rain, and the collision of raindrops with the air can also have an effect on the thunder.

4.Different geographical location, topography, and climatic conditions may also affect the characteristics of thunder.

Taken together, the combination of these factors leads to the anomaly of thunder sounds in the middle of the night.

Thunder is the sound of clouds with positive and negative charges in the sky meeting and colliding and discharging, and the area is very large, so it is not a boom, but a lot of times, and there is a strange rumbling sound.

When thunder, the first thing to do indoors is to close the doors and windows, cut off all the power supplies at home, and do not use electronic devices, which can avoid damage to electrical appliances and reduce the probability of lightning strikes.

Thunderclouds form under conditions with ample water vapor and intense convective movements. In winter, due to the cold and dry air and weak solar radiation, convection is not easy to form in the air, so thunder and lightning are rare. However, sometimes thunderclouds are formed in winter when the temperature is high, and thunder and lightning are generated, and rain and snow occur.

Convection is particularly strong and can also form hail, which creates the so-called "winter thunder" weather phenomenon.

Because the air is extremely unstable when it rains, it is easy to have a strong upward convective movement, and the formation of towering cumulonimbus clouds, some of these clouds have a positive charge, some have a negative charge, when the two clouds meet together, they will discharge, emitting very bright lightning, and at the same time emitting a lot of heat, so that the surrounding air is quickly heated, expanded, and makes a loud noise.

The clouds in the humid weather are full of water vapor rushing up and down, which will produce static electricity, the upper end of the cloud will produce a positive charge, the lower end of the cloud will produce a negative charge, and the ground is a positive charge, and the voltage difference between the positive and negative charges is large enough to break through the air of the insulator, so that the temperature of the surrounding air increases sharply to produce thermal expansion, and then pushes the air to form a ** wave, which will produce thunder.

At the same distance, the stronger the glow of lightning, the greater the thermal radiation energy generated, and thus the higher the magnetoelectric induction on metal conductors, which will be accompanied by strong magnetic field radiation and damage to power and communication equipment. Therefore, during thunderstorms, do not use electronic devices such as televisions that send electromagnetic signals to the outside to prevent lightning damage.

"Thunder rings because electricity generates heat when it passes through the air, causing the air to expand rapidly and make 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. ”

It shows that Thunderbolt is very close to you, and it is really helping you look forward to adoption

The sound of thunder is very loud, which is a very normal weather phenomenon.

The reasons why there is sometimes thunder and sometimes no thunder on rainy days are as follows:

Thunder sometimes doesn't sound when it rains because: Thunderstorm is a large weather phenomenon caused by natural factors such as electrostatic induction, wind shear, and tropical cyclones. And when it rains, there are a lot of clouds in the sky, and when lightning passes through the clouds, the conductors connect the clouds and the earth, which leads to the passage of electric current.

Since the flow of electric current will produce a magnetic field, the surrounding metal will be attracted by the magnetic field, resulting in sparks and flashes.

If there is only thunder and there is little thunder when it rains in some areas, this may be due to the phenomenon of "wet tail". Wet tail refers to the phenomenon of lightning that was not heard when it happened, but then rained down. This is due to the fact that when lightning occurs, part of the cloud layer is broken down and an electric current leaks, causing some water vapor to condense in the air to form rainfall.

Therefore, thunder occurs only when it rains in some areas, and the thunder is low, which may be due to the wet tail phenomenon.

If you don't hear thunder when it strikes, it may be because you're on the edge of a thunderstorm. A thunderstorm is a very violent weather phenomenon that is usually accompanied by natural phenomena such as strong winds, torrential rain, blizzards, etc. When thunderstorms occur, natural factors such as electrostatic induction, wind shear, tropical cyclones, etc., occur simultaneously.

If you're on the edge of a thunderstorm, you may only hear part of the thunder, or you won't hear it at all.

I hope the above information is enough to solve your doubts, if you have any other questions, please let me know.

Thunder and lightning will occur on rainy days because when the air is extremely unstable, it is easy to have a strong upward convective movement, and the formation of towering cumulonimbus clouds, the clouds are filled with water vapor running up and down, static electricity will be generated, the upper and lower ends of the cloud will produce electric charges, and the air will expand in an instant** Thunder, and the electric spark emitted is lightning.

Why thunder and lightning when it rains.

When it rains, some of the clouds in the sky are positive and some are negative. When two clouds collide, lightning strikes, and at the same time emits a lot of heat, heating and expanding the surrounding air. The air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration, which is thunder.

Thunder and lightning are the phenomenon of electrical discharge in thunderstorm clouds. The formation of thunderstorm clouds generally requires two conditions, sufficient water vapor and violent convective movements.

Lightning is a phenomenon of intense electrical discharge between clouds, between clouds and the ground, or between parts of the cloud. Usually storm clouds (cumulonimbus clouds) produce electric charges, with yin electricity at the bottom and yang electricity at the top, and also a positive charge on the ground, which follows the clouds like a shadow. Positive and negative charges attract each other, and the positive charges run towards trees, hills, the tops of tall buildings, and even the human body, reaching down and getting closer to the ground.

Eventually, the negative charge of the cluster base finally overcame the barrier of air and connected, and a huge electric current surged along the conductive airway from the ground to the clouds, and lightning was generated.

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. <>
