Why don t you stand under a tree during a thunderstorm

It is not safe to take shelter from the rain under a tree and is susceptible to lightning strikes.

Why? Because from a physical point of view, electricity has the phenomenon of "tip discharge". So how do you understand "tip discharge"?

We can imagine that there is a piece of charged dielectric, and we make it in two shapes: spherical and cone-shaped. Then the charge surface density on the spherical charged body is certain, which is smaller than the vertebrae apex of the conical charged body, so that the charge at the tip is larger, and the ability to attract objects is stronger, and if there is a candle next to it, we will see the offset of the flame. The famous Van der Graaf starting motor is made using this principle.

Our common "lightning rod" is also made according to this principle. Therefore, lightning in the sky is attracted to pointed objects (note that they are "pointed" rather than "high", and sharp objects in a large area are represented as tall objects. Therefore, lightning is a volume that hits a high object, so it is scientifically reasonable to not be able to shelter from the rain under a tree or a tall building on a rainy day.

However, if the energy of the lightning is very large and the surface area is small, and the object is not enough to attract or the lightning is offset to hit the room, it is also possible, but in terms of probability, this is indeed a small probability event.

When there is a thunderstorm in summer, there will be thunder in the air, thunder is a phenomenon of air discharge, there will be a strong electric current through a protruding object on the ground, such as tall buildings or trees, may attract thunder and lightning, if you stand under a tree on a rainy day.

Thunder and lightning often flash over the ground when it will split the ground higher places, such as trees, when lightning cleaves trees, it will also split people, so you must not stand under the tree on rainy days, otherwise it will cause life danger, when you encounter a thunderstorm outside, do not panic, to take shelter under the eaves, if there is no eaves nearby, it is only possible to run to safety.

Because, standing under a tree, the thunder strikes the tree, and the tree will hit you.

Thunderstorms can not hide under the rain, if you hide under the rain, it will bring you fatal danger, we all know that thunder or lightning, is between the clouds and the clouds, the clouds and the ground, the current generated inside the clouds, this current will pass through the rain in the trees, if the person is under the tree at this time, the strong current will hit the human body, will give a fatal blow, so that people lose their lives.

When the human body comes into contact with a large tree, a strong lightning current flows through the trunk of the tree, generating a high voltage that knocks the person down. This is because the human body is in direct contact with this high voltage, commonly known as contact voltage injury.

The second is that although the person has not been in contact with the tree, the lightning current flows through the trunk of the tree to produce a voltage that is high enough to discharge the human body through the air and cause injury, which is usually called counterattack injury. In addition, although people do not have direct contact with the tree, and there is a certain distance from the tree, because standing under the tree, when the strong lightning current flows into the ground through the tree and spreads around, it will produce different voltages in different places, and there is a potential difference between the feet of the human body standing, so there is an electric current flowing through the human body to cause injury. Commonly referred to as step voltage damage, the discharge object of a thunderstorm is selective, and the lightning current always chooses the closest and most conductive path to the earth.

That is, it is easy to discharge the highest object in the occurrence area;

Large trees are higher than the ground and tend to form loops with lightning strikes during lightning. In this way, you become a conductor for electrical discharge under the tree. Of course, there are also places where lightning strikes are higher than large trees.

In an open place, trees and people tend to be the tallest, so they are often struck by lightning. Therefore, open fields, beaches, seas, and even football fields and golf courses are very dangerous places during thunderstorms.

In the urban area, many large trees are very close to the overhead line, and the usual safe distance is enough, but in thunderstorms, the air is humid, especially when there is wind. Even if there is no lightning, there is a good chance that the tree will be energized to the line. Standing under the tree, you are the conductor of the leakage of the overhead line.

Generally, overhead lines, especially those on the main street, are 10,000 volts. You can basically activate it in the open air. Of course, there are also disadvantages of leakage and more dangerous places under the big tree, such as:

Transformer pole underneath!

Even if there is no danger of lightning strikes and leakage, rain will make the ground wet and hard. Especially in cities, trees are not deeply rooted, and it is easy for trees to fall or break branches when continuous rainfall and strong winds occur. Then you become a cushion for the tree to fall.

It is easy to be struck by lightning. The big tree is relatively tall and is a good conductor of thunder and lightning, and to take refuge under the big tree is undoubtedly to use yourself as a lightning rod.

When thunder, a large number of negative ions will be produced in the air, and they will collide with each other to produce electric charges, these negative ions will adhere to relatively high objects, easy to attract lightning, lightning splitting down with a great current, because the tree is not a good conductor, the resistance of the trunk is relatively large, so the current will stop pouring directly from the tree to the earth. In the process of sheltering from the rain in the tree, when the thunder and lightning of the big tree reached the top of the person's head, an electric arc flashed down, flashed and hit the person's head, and then poured down into the ground through the human body.

Because the height of the trees is relatively high, it is especially easy to attract lightning during thunderstorms, so it is easy to be struck by lightning when hiding under large trees.

Because trees are very tall, if lightning strikes that tree, it will generate electricity along the tree, which will cause harm to people. So it's better not to stand under a tree.

This is because during a thunderstorm, it may be easy to be struck by lightning under a large tree, causing some life safety hazards.

Because wet wood is electrically conductive, and because trees usually grow very tall, it is particularly easy to be struck by lightning, if people stand under a big tree during a thunderstorm, it is easy to be struck by lightning.

This is because in the process of sheltering from the rain under a large tree, it is easy to be struck by lightning, and it can also be life-threatening.

Because damp trees are conductors, hiding under the trees, we have a particularly high chance of being struck by lightning.

Whenever summer comes, the lightning weather always increases. This is a normal weather phenomenon, but lightning also causes a lot of people** and natural disasters. Rural areas, in particular, seem to be the hardest hit by lightning strikes, and it is often said that they died from electric shocks or that electrical appliances were burned.

Rural areas have also developed faster and faster in recent years, but there is still such news, what is the reason?

The prevalence of lightning strikes in rural areas is closely related to buildings. The houses in the city are relatively tall, and safety is also fully considered when building, and high-rise buildings have lightning protection devices, so household appliances are rarely damaged by lightning. The rural areas were mostly residential, with almost no lightning rods on the roofs, and early rural houses did not have grounding wires connected when installing circuits and switch sockets.

This leads to a great safety hazard, and there is a high probability that the electric current caused by lightning will burn the appliance.

When we were children, when we were reading texts, we learned that we should not stand under a big tree on a rainy day and it would rain heavily. Because rainy days can be accompanied by thunder and lightning, lightning usually transmits protrusions or electricity from the ground. Trees not only conduct electricity, but they also provide rain.

If a person is standing directly under a tree, there is a high chance that he will come into contact with the high-voltage current caused by lightning, so if he is hit, it will be difficult to survive.

The whole process of the tree being struck by lightning is fast, so it can only evaporate the water of the tree in such a short period of time, and it cannot ignite the trunk. Of course, small twigs can catch fire due to the strong heat, but lightning tends to only happen on rainy days, so sporadic fires are also extinguished by the rain, eventually leaving behind split trees.

Of course, you should never stand under a tree on a rainy day. This is because it increases the danger of direct human contact with trees. For example, when a tree is struck by lightning, a person will naturally become a conductor, producing contact lightning.

Also, for example, you don't come into contact with a tree when you stand under it, but when lightning touches a tree, a strong electric current will form radioactivity around the tree.

Who is more struck by lightning?

1.A person standing on a high place.

Lightning is from top to bottom, so it usually hits the tallest object, so avoid turning yourself into the tallest object or standing near the tallest object.

2.People who take shelter from the rain under trees.

Thunder and lightning strike the trees, and lightning currents pour down through the trunks. If someone under the tree is sheltering from the rain, the thunder and lightning from the tree can easily be channeled into the human body, and the person will be injured.

3.People who stay in open spaces.

On rainy days, people become the commanding heights in the open field, and like a lightning rod, they are easy targets for lightning.

4.People who go crazy in the rain.

Thunderstorms are not suitable for outdoor sports, nor are they good for driving a motorcycle, riding a bike quickly, or speeding through the rain. Because the greater the gait of the body, the greater the stepping voltage, and the more prone to lightning injuries.

5.People with metal objects.

Don't stay in a thunderstorm with metal objects. Because metal objects are electrically conductive substances, they sometimes play a role in attracting thunder during thunderstorms.

Because the branches and leaves on the top of the big tree are relatively slender, it is easy to attract lightning, which is why the lightning rod can protect against lightning. Although branches and leaves can attract lightning, the trunk is a bad conductor and cannot completely transmit lightning. Of course, if there is water inside and outside the trunk, it can also conduct electricity, but the effect is negligible.

Because if you split it, it will definitely be a relatively high thing, and the tree is like a lightning rod, so it will be more dangerous, so try to stay away.

Because on a rainy day, there is a high chance that two dark clouds in the sky will collide and cause lightning, and the food on the ground is relatively high enough to attract thunder, so it is easy to be struck by lightning.

Because standing under a tree during thunder will expose you to lightning strikes, you can't stand under a tree during thunder.

When a person comes into contact with a tree, a strong lightning current flowing through the trunk creates a high voltage that knocks the person down. This is because the human body is directly exposed to this high voltage, commonly known as contact voltage injury. Second, although a person does not come into contact with a tree, the high voltage generated by the lightning current flowing through the tree is enough to discharge through the air and cause harm to the human body, which is often referred to as counter-attack injury.

Then there is no direct contact with the tree, but there is a certain distance from the tree, but because standing under the tree, when the strong lightning current spreads through the tree into the ground and spreads around, it will produce different voltages in different places, and there is a potential difference between the feet of the human body standing there, and there is a current flowing through, causing harm to the human body.

Commonly known as stepped voltage destruction, the discharge object of a thunderstorm is selective. Lightning currents always choose the closest, most conductive path to discharge to earth. i.e. easy to discharge to the tallest objects in the area; Because rain is conductive, and because the tree is very close to the thunderbolt, the thunder and lightning will automatically discharge along the nearest tree or building to the earth, and the voltage and current of the thunderbolt are very strong, standing under the tree in the thunderstorm is easy to be hit, easy to be electrocuted, the tree is higher than the person, and the probability of electric shock is very high.

Do not hide under a tree on a rainy day, if you have to stay under a tree, keep a distance of more than two meters from the tree or branches, squat down with your feet together as much as possible, put your hands on your knees, and do not touch the ground with your arms. If you can achieve better results with a raincoat, never lie on the ground. Avoid huddles together.

The trees are tall and chirping, and they are attracted to lightning. Thunder is high-pressure, and when trees spread underground, they can hit nearby things and get hurt.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Because the tree is very humid during thunderstorming, it will become a conductor of electricity, so it is very easy to be struck by lightning when hiding under the tree.

Because if you hide under a tree, you will be struck by lightning, the tree is very tall, and there is a lot of water in the body of the tree, so the chance of being struck by lightning is relatively high.

Because lightning strikes some tall things, trees are very tall, so they are very susceptible to lightning.

Introduction: Many people don't know why they can't hide under a big tree during a thunderstorm and don't know what to expect.

Many people don't know why they can't hide under a big tree during a thunderstorm, and they don't know what kind of impact it will have, so they must use it in the right way. If you find thunder, be sure to avoid big trees and go to a safe place to protect yourself. Many people like to take shelter from the rain under a big tree, and if you hide from the rain under a big tree, it will be easy to hurt yourself if there is lightning in the sky, so you must learn to protect yourself.

If it rains and you want to take shelter from the rain, you must choose a safe place so that you can better protect yourself, and if there is a thunderstorm, you must avoid big trees and do not encounter lightning strikes. When many people choose to shelter from the rain, they must choose the right way, do not let themselves always stand under the big tree, do not feel that it is safe under the big tree, and must adjust some of their usual habits. Many people will also feel uncomfortable in the process of sheltering from the rain, so they must bring their own umbrellas appropriately.

Many people must take a look at the weather of the day when they go out, and if the weather is raining, they must bring their own umbrellas, and do not let themselves hide from the rain under the big trees, which will also cause danger to themselves. When many people are sheltering from the rain, they must take a look at whether their surroundings are safe, and they must try to hide under the house as much as possible, and do not hide under the big trees, which will also cause great danger to themselves. Many people always like to play under the big tree, at this time must not enter a bad place, and do not let yourself be left alone, to go to a crowded place to find a suitable way, you can go to a better place appropriately.

If there are always a lot of thunderstorms, you should change yourself appropriately, don't let yourself be in this situation, and be sure to adjust your state appropriately, so that you can better avoid the rain.
