There are certain conditions for the formation of thunderstorm clouds, that is, there must be sufficient water vapor in the air, there must be a power to make the moist air rise, and the air must be able to produce violent convective movements. In spring and summer, due to the influence of the warm and humid airflow from the south, the air is humid, and at the same time, the solar radiation is strong, the air near the ground is constantly heated and rises, and the cold air in the upper layer sinks, which is easy to form strong convection, so there are many thunderstorms and even hail.
In winter, due to the cold air mass of the continent, the air is cold and dry, and the solar radiation is weak, the air is not easy to form violent convection, so thundershowers rarely occur. However, sometimes the weather is warm in winter, and the warm and humid air is stronger, and when the strong cold air in the north occasionally goes south, the warm and humid air is forced to rise, and the convection intensifies, thundershowers will be formed, and the so-called "thunder winter" phenomenon appears. Meteorologists also say that the generation of thunderstorms does not depend on the temperature itself, but on the distribution of the temperature up and down.
In other words, although the temperature is not high in winter, if the temperature difference between the upper and lower reaches a certain value, strong convection can also be formed, resulting in thunderstorms. Winter thunderstorms are rare in China, but they are common in winter in Toronto, Canada.
When the air is extremely unstable, it is easy to have a strong upward convective movement, and form a towering cumulonimbus cloud, the cloud is full of water vapor rushing up and down, it 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, then, there is air as an insulator between the positive and negative charges, if the voltage difference between the positive and negative charges is large enough to break through the air of the insulator, so that the air expands in an instant**, heats up and glows, and the light is lightning, expanding** Making a loud noise is thunder. That's why the house shook.
-
The frequency of the sound waves emitted by thunder, close to the natural frequency of the house, resonates.
-
Thunder produces strong sound waves that can be felt by a person, as if the house is vibrating.
-
is the physical connection effect of sound waves.

The possibility of a house being knocked down by a thunderstorm is almost non-existent, and the reason is that in one".EarthquakesLiterally. Because thundershowers mainly play a destructive role in heavy rain, thunder will also play a destructive role in high-rise buildings without lightning protection facilities, such as in the early years of wooden power poles without lightning protection facilities, there are power poles split by lightning. In rural areas, there have been cases of spherical mines breaking through the adobe of farmhouses.
There have even been cases where a corner of the ancient tower has been struck off by lightning. But that's the action of an extremely powerful electric current, not a vibration.
Nowadays, buildings are equipped with lightning protection facilities, and there are almost no reports of damage to houses caused by thunderstorms, so there is no such thing as thunderstorms collapsing houses.

What a thunderstorm you have. Trouble may collapse your house.

Thunder is the sound made when a thundercloud discharges electricity to the ground.
Due to various reasons, clouds in the air lose or gain an electric charge, making their voltage to the ground higher and higher, and when it reaches a certain value, it will break through the air and discharge to the ground, which may also cause damage to buildings.
Why thunder when it rains, because rain generally has a certain acidity, which makes the air humid, and the insulation strength of the air is greatly reduced, so most of the thunder phenomenon occurs when it rains.
The sound waves of the sound emitted when the thunder strikes are transmitted to the building, just like if you hit the wall with an object, the wall will vibrate, but the difference is that it is direct contact, and the thunder strikes the building through the sound waves.

Proportional also. 1.The impact of sound waves. 2.Psychological effects 3Thunder and lightning disrupt your nerve currents, and there is dizziness to drive away.
In the countryside, the yard of each household is generally relatively large, but I always feel that no matter how big the place at home is, it is full of piles, and I can't put anything at all, and I always feel that it is not enough. Why is that? Today we are going to talk about this topic. >>>More
Personally, I think there are many reasons, but many times the house does not move, and the window glass vibrates, so I think it is the house that shakes. When the car walks by, the general weight of the car does not have a great impact on the ground, but the car will have the influence of sound and airflow, which will drive the change of the surrounding air, and then when the influence range reaches the glass, it will cause the window to tremble, which may be related to the resonance frequency.
Exercise more and stay at night, pay attention to nutritional supplements, eat more fruits, and drink a glass of milk before going to bed.

First of all, for some friends, they may have not fully repaired due to the fatigue of the previous period, so there will be a period of time when they have not done anything every day, and they will also feel very tired. In this case, you need to relax yourself and rest for a period of time to be able to better devote yourself to life and work. >>>More
