Is it useful to close the windows when it is thundering?

Weather changes are a normal phenomenon, but we will close the windows of our homes when it thunders and rains, and closing the windows when it thunders has a partial effect, which can be explained as follows:

Clause. 1. Close the windows when thunder can reduce the noise of thunder. Especially in the summer, the weather changes more strongly, the sound of thunder is relatively loud, at this time if the window is closed, the window has a certain sound insulation effect, if the home is installed with a sound insulation effect of the window effect will be better, it will make the thunder a lot smaller, especially some families prefer to be quiet or have a baby who is afraid of thunder, the effect of closing the window at this time will be much better.

Clause. Second, generally thunder is raining together, and the weather that only thunders and does not rain is relatively rare. Therefore, closing the windows during thunder can be said to be a prevention of bad weather, especially when you are about to go out, at this time, you don't have to worry about the rain drifting into the house, adding security to the safety of the family brought by bad weather.

Clause. 3. Closing the windows has little effect on the damage of lightning to household appliances. Especially in some big cities, the floors are very high and more susceptible to lightning attacks, these buildings are generally equipped with lightning protection facilities, if there are no lightning protection facilities, just close the windows to thunder has almost no effect, so you have to turn off the power supply at home.

However, for small buildings in rural areas, many families are not equipped with lightning protection facilities, at this time, in addition to closing the windows, it is better to turn off the power supply at home, otherwise household appliances may be struck by devastating lightning, and even cause a fire in the home.

In short, closing the windows during thunder has a certain effect on sound insulation or preventing rain, and it basically does not have much effect on preventing lightning strikes.

Definitely useful Otherwise cable TV can be struck by lightning.

Yes. Usually, lightning affects the safety of household appliances caused by the intrusion of induction lightning. Induced lightning refers to the electromagnetic pulse of lightning generated when lightning enters various metal pipes and lines of the building when lightning occurs.

For a family, there are four main ways for induction lightning to penetrate: power supply lines, ** lines, feeders of cable TV or wireless TV antennas, and external walls or pillars of houses.

Expert advice: When a thunderstorm is raging, it is best to stay inside and close the doors and windows to prevent lightning from invading. Thunderstorms can easily damage home appliances, but as long as you do a good job of protection, you can easily avoid thunderstorms.

During a thunderstorm, it is best to disconnect the power supply and antenna plugs of various electrical appliances and communication equipment, and do not use them temporarily. At this time, in order to ensure your personal safety, you should also try to avoid touching metal pipes and do not use shower equipment.

Indoor lightning protection.

1. When thundering, the first thing to do is to close the doors and windows to prevent lightning from hitting the room directly or spherical lightning from drifting into the room.

2. In case of thunderstorms, people should not stand under the bulb, and the power supply of household appliances should be cut off to avoid damage to electrical appliances.

3. During thunderstorms, try not to call, answer or use the Internet, and unplug the power supply and the metal wires that may introduce lightning such as the closed line of the TV and the TV.

4. Leave the metal water pipe and the sewer pipe connected to the roof indoors.

5. Do not pull the wire used for drying clothes and bedding to the window or door, so as to prevent the death of people caused by lightning caused by wire.

Outdoor lightning protection. 1. During thunderstorms, do not answer and call mobile phones outdoors, because the electromagnetic waves of mobile phones will also lead to thunder. At the same time, it is strictly forbidden to approach some power facilities that are operating during thunder.

2. People will generally not be attacked by lightning when they are in the car, but they should not put their heads and hands out of the window when they encounter thunder in the car.

3. In the event of a sudden thunderstorm, when the hair is stiff and stands up, you should squat down, reduce your height, and at the same time bring your feet together to reduce the harm caused by the stepping voltage.

4. Do not take shelter from the rain under a large tree. It is best to stay 5 meters away from large trees during thunderstorms.

5. When going out in thunderstorms, it is best to wear rubber shoes, which can play a role in insulation.

Basically not, this situation rarely happens, people indoors, the house itself constitutes a protective cage, and now the house generally has a lightning protection device, lightning can not be indoors.

There is no lightning rod.

should turn off the power supply in your home, because even if lightning does not hit the house, it may damage the electrical appliances in your home. When lightning strikes next to your house, the changing lightning will produce a changing magnetic field, and the changing magnetic field will produce an electric current, which is a phenomenon of electromagnetic induction.

It can make the metal wires in the home generate additional current, and the current overload will instantly burn the electrical appliances.

A house with a lightning rod may also be affected by lightning, the role of the lightning rod is to protect the building, and a large number of induced charges are gathered at the top of it, which can first combine with lightning and lightning to quickly channel lightning into the ground to ensure the safety of the building. However, the home power grid is externally powered, and if lightning strikes the external power grid, it can generate tens of thousands of volts of voltage in an instant, and directly burn the home appliances through the line.

Pay attention to the following points in thunder and lightning weather:

1. Don't stand under a light bulb indoors. When lightning strikes the light bulb line, it will increase the energy of electricity in an instant, overload the bulb, and release ultra-high light energy and heat energy in an instant, thus causing burns to the human body.

2. Don't pick up **. Try not to hit ** when thunder and lightning, or use a computer to surf the Internet, you should unplug the ** line and computer network cable, so as not to cause lightning strikes in the corresponding line, and do not use your mobile phone to receive ** when thundering, which will not only cause damage to the mobile phone but also increase the risk of lightning strikes.

3. Outdoor exercise is not suitable. During thunderstorms.

Do not exercise outdoors, if you encounter a thunderstorm during outdoor sports, you should find a suitable shelter as soon as possible to avoid lightning strikes, and do not open an umbrella when outdoors to avoid tip discharge.

Caught in a lightning strike.

If you are at home, if the windows are not closed, you may be killed by thunder and rain.

Because there is a kind of ball lightning that is very scary, it can enter the room through the cracks in doors and windows.

This should be impossible to be normal, no problem, unless the big spherical mine is more powerful, the other mines are not so powerful, don't worry. But to be on the safe side, it's better to close the door on rainy days.

Under normal circumstances, people are indoors and will not be struck by lightning.

However, in special cases, such as when a person happens to touch a metal object connected to the outdoors, there is still a ...... that may be struck by lightning

So, on a thunderstorm day, you really need to pay attention to safety!

In addition......If you don't close the window, it won't affect ......

Of course not, there are lightning rods on the roofs.

Close the windows when thundering. When encountering thunder, the first thing to do is to close the doors and windows to prevent lightning from hitting the room directly, or to prevent spherical lightning from drifting into the room. And the wire for drying clothes and bedding should not be pulled to the window or door to prevent the wire from causing lightning.

In addition, the power supply of household appliances should be cut off immediately to avoid damage to the appliances.

Thunder is a natural phenomenon, and when it rains, some clouds in the sky have positive poles and some negative poles. 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.

This 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. 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 hailstones, which can produce the so-called winter thunderstorms. Knowing these reasons, it is not surprising that there is a winter thunderstorm.

Keep windows closed when thunder strikes

When thundering, it is relatively safe indoors, but keep doors and windows closed to prevent dangerous side lightning and ball lightning from intruding.

Live on a high floor and don't go near the window when it's thundering. Now there are more and more high-rise buildings, these high-rise buildings will have more opportunities to contact lightning, in addition to installing lightning rods and lightning belts on the top floor of the building, it is also necessary to make a pressure equalizing valve every two floors; All windows in the building must be connected to the building's polar installations. Because lightning rods and lightning belts are mainly used to prevent direct lightning strikes, while side lightning strikes are not enough to rely on lightning rods alone.

So now it doesn't matter if lightning strikes a high-rise building, lightning will follow these lightning protection devices into the ground, and there is no destructive effect on the building. However, experts still advise people who work in high-rise buildings to try not to stand by the window when thunder strikes, so as not to cause danger.

What is the cause of thunder

Electricity is the phenomenon of electrical discharge in thunderstorm clouds. 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 control of the continental cold air mass, 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.

You can't open the windows when thundering.

Be sure to close doors and windows when thundering. First, because the opening of windows and doors will form air convection, which is easy to cause ball lightning and cause potential safety hazards. The second is to prevent "rolling ball mines.""As the air enters the room, because of the "rolling ball thunder.""It will flutter with the air flow, and the opening of the window will introduce the air flow of the mold wheel front, increasing the risk.

In addition to closing the window, you should not stand by the window when thunder, because the glass is insulated from the wind but not electricity, and lightning can enter the room through the window.

In addition to installing lightning rods and lightning belts on the top floor of the building, there will be pressure equalizing valves every two floors, and all the windows of the building will be connected to the polar devices. Therefore, it is relatively safe to stay indoors during thunderstorms, so you don't have to worry too much.

The correct way to deal with the weather in the thunderstorm section

1. Close doors and windows and do not stay by the windows, cut off the power supply of indoor routers, refrigerators and other electrical appliances in time, and do not touch gas pipes, water pipes and various live devices.

2. When indoors, you should leave the lighting line, the first line, the radio line, the TV antenna and the various conductors connected to it, and turn off the mobile phone, remove all the communication signal equipment around you, and prevent the secondary discharge of these lines and conductors to the human body.

3. When outdoors, wear a plastic raincoat in time, and enter the building with a wide metal frame or lightning protection measures as much as possible.

4. It is forbidden to take shelter from thunderstorms under big trees, and if there are tall trees around, keep a distance of at least 5 meters from the trunk, squat and keep your legs together.

The hazards of lightning are divided into three types: direct lightning, induction lightning and spherical lightning, and the most common are direct lightning and induction lightning. Direct lightning strikes are lightning strikes directly on an object; Induction lightning is induced by the conductor of electricity such as metal objects next to the target by lightning, and indirectly hits the object; Spherical thunder is commonly known as a folk.

A rolling mine is an orange or red flame-like glowing sphere, and also has a yellow, green, blue, or purple diameter of a spherical mine.

Generally in 20 to 30

centimeters, the largest spherical mine diameter can reach.

About 1 meter. It can enter the room along the holes of the building or open doors and windows, and most of them disappear along the electrified body, but if it encounters flammable materials, such as clothing, bedding, wood, etc., it is easy to cause combustion. The most common spherical mines are rolled down large trees and sometimes drifted indoors.

Indoor lightning protection tip 1

When thunder, the first thing to do is to close the doors and windows to prevent lightning from hitting the room and spherical lightning from drifting into the room. 2．

Leave the metal water pipes that enter the house and the sewer pipes that are connected to the roof when you are indoors. 3．

During a thunderstorm, try not to call, answer, or use the Internet, and unplug the power supply and metal wires such as wire and TV feeder that may introduce lightning. The safe and scientific way is to install the power arrester on the power line, install the lightning arrester on the line, install the lightning arrester on the antenna feeder and do a good job of grounding. 4．

Keep the house dry, and if the house leaks, it should be repaired in time. 5．

The insulator iron feet of the incoming power cord should be grounded, and the three-phase socket should be connected to the grounding wire. 6．

Do not pull the wire used for drying clothes and bedding to the window or door to prevent the wire from causing lightning. 7．

Do not stay in isolated gazebos, grass huts and houses for long periods of time, take care to avoid power lines, do not stand under light bulbs, and preferably cut off electricity or do not use electrical appliances.
