What should I pay attention to when thunder and lightning?

Close doors and windows, don't hit.

Don't hit **.

Turn off the power.

Thunder and lightning are 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.

1. Don't venture out unless absolutely necessary. Stay indoors.

2. Do not approach open doors, windows, stoves, radiators, metal pipes, gutters, and electrical appliances plugged in.

3. Do not use plug-in electrical devices such as hair dryers, voltage brushes or electric shavers during storms.

4. During the storm, do not use **, lightning may hit the outside ** line.

5. Don't go to the clothes on the clothesline.

6. Do not engage in the installation of fences, power lines, pipelines or construction steel.

7. Do not use metal objects such as fishing rods and golf clubs. Golfers who wear shoes with nails made excellent lightning rods.

8. Do not dispose of flammable materials in open containers.

9. Get out of the water and the boat.

10. If you are traveling, then stay in your car, which is often an excellent lightning protection facility. When there is no shelter, avoid the highest objects in the area. If there are only isolated trees nearby, your best defense is to crouch in the open air and stay twice as tall away from the isolated tree.

11. Avoid agreed, open spaces, wire railings, metal clotheslines. Open sheds and any conductive objects that protrude from the ground.

12. When you feel an electric charge, i.e. if your hair stands on end, or your ** flutters, then you may have received an electric shock. Immediately fall to the ground. People who have been struck by lightning will be in severe shock and may be burned, but they are not charged and can be safely handled.

People who are stunned by electrocution are usually able to wake up with timely mouth-to-mouth breathing, cardiac massage, and prolonged artificial respiration. In a group of people who have been electrocuted, the apparent death should be dealt with first. Those who still show signs of being alive may recover on their own.

The above content refers to the encyclopedia of lightning.

Lightning usually hits the spire of the tallest object outdoors, so isolated tall trees or buildings are often the most vulnerable to lightning strikesPeople should follow the following rules outdoors to ensure safety when lightning strikes: 1. During thunderstorms, do not answer and dial phones outdoors, because the electromagnetic waves of mobile phones will also lead to lightning. 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.

Thunderstorm precautions are as follows:1. When thunderstorm and lightning, do not dial and answer, and unplug the ** line. The phone can be used normally.

However, in general, try not to receive mobile phones outdoors or indoors near a window.

2. When thunderstorm lightning, do not turn on the TV, computer, VCD player, etc., unplug all power plugs, turn off household appliances, and unplug the power plug to prevent lightning from invading from the power cord.

3. Don't stand under the light bulb and don't take a shower.

4. Try not to go out, if you must go out, it is best to wear rubber shoes and a raincoat, which can play an insulating role in lightning.

1. When thundering, close the doors and windows to prevent lightning from hitting the room directly.

2. In the event of a thunderstorm, try not to dial or answer, and unplug the power supply and the cable and TV closed circuit.

3. 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.

4. Keep away from the metal water pipes and sewer pipes connected to the roof.

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.

On land, there are more opportunities to occur in the summer afternoon when the thermal convection is strong, forming "hot thunderstorms". At sea, because the sea surface cools slowly at night, the air is very unstable, so night thunderstorms often occur, and frontal thunderstorms can be produced at the same time as thunderstorms are generated near the front, and in mountainous areas, there can be terrain rain. Thunderstorms are generally gusty, often with strong winds, sometimes accompanied by tornadoes and hail, persistent and intense thunderstorms, often up to the level of heavy rain, the most active thunderstorms in the world are in the tropics and mountains.

There are an average of 75-100 thunderstorm days per year in the tropics, 20-50 thunderstorm days in the mid-latitudes, only a few thunderstorm days in the polar regions, and no thunderstorms all year round north of 82 degrees north latitude. The most thunderstorms in the world are Bogor City, Indonesia, with an average of 322 thunderstorm days per year, so it is known as the "thunderstorm capital of the world", and the area with the most thunderstorms in China is the Nanling Mountains, with an average of 50 thunderstorm days per year. Nada City on Hainan Island has an average of 130 thunderstorm days throughout the year, and is known as the "Thunder Capital" in China.

Close doors and windows, try not to play with mobile phones, do not touch metal devices, do not take shelter from the rain in buildings without lightning protection facilities, and do not ride bicycles. At home, it is best to turn off some major appliances to avoid damage to household appliances. When thunder and lightning strike, try to avoid traveling, and find a place to shelter from the rain outdoors.

When it is thundering and raining, it is strictly forbidden to stay on the top of the mountain or high hills, not to take shelter under big trees, near the telephone pole and the model belt, and do not walk or stand in the open field, you should try to find a house to take shelter as much as possible.

Do not use an umbrella with a metal handle, take off metal objects on your body, and if you are still riding, leave the bicycle as soon as possible, and stay away from other metal objects to avoid being struck by lightning.

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