When it rains, why can t you stand under a tree to shelter from the rain?

From the formation and process of lightning and thunder, on open fields, on the roofs of buildings, under tall trees, near rivers and lakes, swimming pools and wet areas are lightning accidents. When you encounter thunder, you should stop outdoor activities and find a lightning shelter as soon as possible, you can go to a low-lying, dry or windy or cave. However, you will not be able to enter low-lying timber buildings, such as mineralized facilities such as mine houses.

When driving, if you are driving, do not "abandon your car" to avoid it, you should stay in the car. The car shell is metal, and because of the shielding effect, there is no harm in the car, and the car is an ideal place to avoid lightning strikes.

When the human body comes into contact with a large tree, a powerful lightning current flows through the trunk to capture the high voltage. This is because the human body is in direct contact with this high voltage, which is often referred to as contact voltage damage. Second, while people do not come into contact with large trees, lightning currents generate high voltages to cause damage to the human body through the air, which is often referred to as counter injury.

In addition, there is no direct contact with the tree, and it is also a certain distance away from the tree, but because the strong thunder flow through the tree, it will produce different places. There is a voltage, and there is a potential difference between the feet standing, so that there is an electric current that causes damage to the human body. As a rule, the discharge target of the thunderstorm is selected, and the lightning current is always selected, and the path that is most conductive is discharged.

That is, it is easy to discharge the tallest objects in the area.

In an empty place, trees and people tend to be the tallest, so it is usually struck by lightning. Therefore, open fields, beaches, oceans, and even football fields, golf courses, are very dangerous in the weather of thunderstorms. On days when thunderstorms are common, try to avoid going to these open areas as much as possible.

When you see lightning in the suburbs, you immediately hear thunder, which means that you are in an environment near a thunderstorm. You should stop walking immediately and squat down immediately with your feet together. This reduces the effective height of the human body.

If time permits, the most likely is to go to a nearby low-lying place or squat in a cave. At this time, remember that low houses and trees are not safe places.

Because trees conduct electricity. Trees that grow are wet and conduct electricity, and thunder is people who conduct electricity from the tree and indirectly chop under the tree.

It is very unsafe because it is accompanied by thunder and lightning when it rains, and it is easy to be struck by lightning when standing under a tree.

Because standing under a big tree, when a strong lightning current flows into the ground through the big tree and spreads around, it will produce different voltages in different places, and the voltage difference between the two feet of the human body will cause injury, which is usually called step voltage injury. If you have to take shelter from the rain under a tree, you must keep a distance of 3 meters from the trunk.

Because hiding under the tree on a rainy day will be struck by lightning, the tree will become a conductor when it touches the water, and it is very likely to be dangerous, so you can't hide under the tree when it is thundering on a rainy day.

This is because when it rains, it is often accompanied by thunder and lightning, and if you hide under a tree to block the rain, it is easy to attract lightning.

This is because when it rains, thunder is likely to occur, and if there is thunder, if you stand under a tree to avoid the rain, you are likely to be struck by lightning and killed by lightning.

Because standing under a big tree, there will be a strong lightning current, which will produce different voltages, and standing with a voltage difference will cause injury, called stepping voltage injury, which is very dangerous, so do not stand under the tree to hide from the rain.

When it rains, it is easy to be struck by lightning when taking shelter under a big tree, and a big tree is equivalent to a lightning rod because of the principle of tip discharge, and the big tree attracts lightning, so don't take shelter from the rain under the big tree.

Because when it rains and stands under a big tree to take shelter from the rain, when the thunder and lightning flow into the ground through the big tree and spread around, it will generate different voltages in different places, and when the human body is in contact with the tree, the strong lightning current will produce a high voltage through the trunk of the tree to knock people down and cause harm to the human body.

Other precautions for thunderstorms:

1. When thunderstorm and lightning, do not dial and answer, and unplug the ** line. Mobile phones can be used normally, but generally try not to receive mobile phones outdoors or indoors near windows.

2. During thunderstorms and lightning, do not turn on TVs, computers, VCD players, etc., and unplug all power plugs to avoid hurting people and damaging electrical appliances.

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.

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, when the human body is in contact with the tree, the strong lightning current flows through the trunk of the tree to produce a high voltage to knock people down, causing harm to the human body, in the days of thunderstorms, first of all, try to avoid going to an open place. <

Standing under the tree, when the strong lightning current flows into the ground through the tree and spreads around, it will produce different Niankong bucket voltage in different places, and when the human body is in contact with the tree, the strong lightning current flows through the trunk of the tree to produce a high voltage to knock people down, causing harm to the human body, in the days of thunderstorms, first of all, try to avoid going to an open place.
