Why is it easy for thunder to slash at tall objects such as trees 10

To be exact, it's not a thunder batch, but a lightning batch, hehe, everyone says thunder criticism in life, so I won't change the statement here).

First of all, why does thunder slash into trees:

Trees are generally high in the open area and relative to the surrounding objects, and when the lightning effect occurs, the trees will act like lightning rods, attracting lightning (lightning) to the earth.

Besides, why does thunder chop down trees and even scorch them into charcoal:

When the current passes through the conductor, it will produce heat, which is proportional to the square of the current, because the voltage of lightning is quite high, and the object will become a conductor to connect with the earth, so when the lightning strikes the object, it is equivalent to instantly heating the object to a very high temperature, causing thermal effects such as melting, ionization, expansion, and combustion. If the tree is approved, the tissue will be destroyed, and of course it will zoom or fall to the ground.

The lightning effect on the upper floor is because the electric current is the easiest to pass through the object with low resistance, relative to lightning, air is equivalent to resistance, the shorter the distance, the smaller the resistance, the distance from the tall object to the cloud is shorter than the ground, which is why the tall object is easy to be hit by lightning.

The reason why lightning will slash into trees: Trees are generally in an open area and relatively high relative to the surrounding objects, and when the lightning effect occurs, the trees will act like lightning rods, attracting lightning (lightning) and directing it to the earth.

When the current passes through the conductor, it will produce heat, which is proportional to the square of the current, because the voltage of lightning is quite high, and the object will become a conductor to connect with the earth, so when the lightning strikes the object, it is equivalent to instantly heating the object to a very high temperature, causing thermal effects such as melting, ionization, expansion, and combustion.

Because big trees are like lightning rods, they are easily struck by lightning.

There are three forms of lightning hazards to people who stay under trees:

1. When the human body is in contact with a tree, a strong lightning current flows through the trunk of the tree to produce a high voltage to knock people down, which is usually called contact voltage injury.

2. Although the person has not been in contact with the tree, the lightning current flows through the trunk of the tree and produces a high voltage that is enough to discharge the human body through the air and cause injury, which is usually called counterattack injury.

3. People do not have direct contact with the tree, and there is a certain distance from the tree, but 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 a current flowing through the human body to cause injury, which is usually called step voltage injury.

The main reasons why trees attract lightning are as follows:

1.There is a lot of water in the body of the tree, and the big tree is relatively tall, the thunder hits the height, if you hide under the big tree, once the thunder hits, the electricity will be transmitted to the human body, the tree is not only a conductor, but also before the rain, the hot air on the surface rises, and the tree will rub and charge. Trees are taller, and when thunder strikes, they attract each other to thunder and lightning.

Lightning is a high-voltage force that can damage nearby objects when it propagates underground with trees as conductors.

2.Rain is conductive, and because the tree is close to lightning, the lightning will rot and walk along the nearest tree or building to discharge the earth, and the voltage and current at the time of lightning are very strong, when there is a thunderstorm, it is easy to be hit and easily electrocuted, the tree is higher than a person, and the probability of electric shock is greater. And once a tree is struck by lightning, the huge energy of the lightning can instantly heat the water in the tree, evaporate it, and then push the hard skin on the outside, and the result can be imagined.

Therefore, in a thunderstorm, we should avoid standing at a high place and near conductive objects to avoid being struck by lightning and causing injury.

Reason 1: Because the electrical system prefers to choose the easiest path to travel, that is, the less resistance there is to the cable.

The more electricity is loved. In fact, the resistance of air is so great.

And the resistance of trees is fine and many times better.

Moisture. The distinction is even more obvious) So d thunder and lightning will choose trees more than air Reason 2: Because the trees are more pointed (compared to the flat silver ground) are attracted by the electric charge of the thunderclouds in the sky.

The charge will be much more concentrated than it would be when the ground is attracted.

So the chances of attracting thunder and lightning are greatly increased P.S. Therefore, a thousand prayers are not used to sound the thunder and use an umbrella in an open place. The resistance is so thin.

It is also the highest point.

And it's so sharp! It's better than a thunderbolt! - Support for questions for the person who asked the question.

Make a targeted.

Trees will not attract thunder and lightning, and if it is an open place, thunder and lightning will first stimulate a tree, and if it is a city, many high-rise buildings will be excited to high-rise buildings, because lightning is electrified. And the electricity system is like to flow to the ground, and the higher the rocky tree, the faster the tree can flow to the underground horn.

5 series uses the word attraction. Most of the wild agitated heights.

Because the tree is very tall, thunder will hit it.

Because of the height of the tree, the thunder catches to the highest point.

Summary. Hello dear. When it strikes, you may be struck by lightning under the tree.

Hello dear. When it strikes, you may be struck by lightning under the tree.

Hello! Being under a tree is dangerous when thunder strikes, as trees are conductors of electricity and are able to absorb and conduct electric current. If you are under a tree, when lightning strikes a tree, there is a high chance that an electric current will enter your body through the trunk, causing an electrical injury.

Therefore, in the event of a thunderstorm, you should avoid staying under trees and find a safe place to take shelter. In addition, if you have a safe area, there are a few things you need to know to help you reduce the risk of being struck by lightning. For example, do not stand above the ground, do not go near metal railings or other conductive materials, and do not stay near water or other wet places.

If you're outdoors, it's best to choose a low-lying place and squat down with your feet together to reduce the risk of being struck by lightning. In short, when thunder strikes, lightning will strike under trees, so you need to pay attention to safety and try to avoid staying in dangerous areas. Hope mine can help you!

Qingxin. Dear, do you have any other problems that you don't understand and need to solve for you?

In thunderstorms, tall trees are generally prone to thunder. Rainwater is electrically conductive, and trees are better when they are wet with rain. In this way, the ground potential is approximately directed to the tip of the tree, and the tree plays the role of lightning rod to guide lightning, but the conductivity of trees is still relatively poor compared with lightning rods.

Generally, the lightning current is tens of thousands of amperes, the energy is huge, the temperature is extremely high, and the trees burst and collapse because they can't withstand such high energy. That's why, in the event of a thunderstorm, personnel should not take shelter under the trees.

On rainy days, the tree is wet and becomes a conductor, and it is easy to be struck by lightning when it is tall, so you can't take shelter under the big tree on a rainy day High-rise buildings need to be equipped with lightning rods to prevent electric shock.

According to reports, one night in the early spring of 1970, the wind roared in the middle and lower reaches of the Yangtze River in China, and it was snowing with rare goose feathers. Suddenly, the sky was filled with lightning and thunder, a rare weather phenomenon that was strange. This year, there is also heavy snow accompanied by thunder on the day of the Lantern Festival in Luxi area.

So, why does it still thunder on a snowy day?

Lightning and thunder are common weather phenomena in summer, while snow is generally in winter, which are two completely different weather phenomena. However, as long as the weather in a certain place is suitable for both snow and thunder, these two completely different weather phenomena can occur at the same time.

Thunderstorms are caused by strong convection of warm and moist air in local places, and the sharp rise of warm air produces violent vibrations of cumulonimbus clouds, which will accumulate a large amount of electric charge and produce lightning phenomena.

At that time, the ground temperature was around zero degrees Celsius, and the conditions for snow were available. At high altitude, warm and moist air climbs violently, and a strong convection phenomenon occurs, forming cumulonimbus clouds, so there is a weather phenomenon of snow on one side and thunder on the other.

There are many currents of air in the air that are constantly moving. There is a direction to these air currents.

Running up, some running down, in different directions, the speed is also different, some are fast, some are slow. The movement of the air currents causes the cumulus clouds in the air to either rush upwards and some downwards. The friction between clouds and clouds causes clouds to carry different kinds of charges. Since the same kind of charge repels each other, it is positive and negative.

The charges are gathered at the ends of the cloud. The faster the air moves, the thicker the clouds, and the more electricity is carried. Cumulus clouds carry electricity reached.

To a certain extent, it will pass through the air and neutralize the two charges. Because electricity generates heat when it passes through the air, it makes it empty.

The gas expands rapidly, resulting in a loud noise, which is called a transport mine.

If the charged cumulus cloud is relatively close to the ground, the electrostatic inductance will cause the ground to carry a different charge than the lower layer of the cloud.

When the charge reaches a certain level, the cumulus cloud will discharge to the ground, which is a landing mine that is easy to cause disasters.

Generally speaking, it is easy to discharge from the ground if there is something protruding, so when we are in the wilderness, we cannot take refuge under the tall trees.

That's a little bit more, hehe).

When dust, ice crystals and other substances in the air tumble and move in the clouds, they go through some complex processes to make these substances carry positive and negative charges respectively. After movement, a heavier substance with the same charge will reach the lower part of the cloud (usually negative), and a lighter mass with the same charge will reach the upper part of the cloud (usually a positive charge).In this way, the convergence of homogeneous charges forms some charged centers, and when the air between the charged centers of the opposite sex is broken down by its strong electric field, a "cloud discharge" (i.e., lightning) is formed

When the negatively charged cloud is close to the ground, the protrusions and metals on the ground will be induced to have a positive charge, and with the gradual enhancement of the electric field, the thundercloud will form a downward pilot, and the objects on the ground will form an upward flash, and the two will meet to form a discharge to the ground.

This can easily cause lightning disasters.

Thunder and lightning are formed during atmospheric motion, which is caused by the violent frictional electricity generated during atmospheric motion and the cutting of magnetic field lines by clouds.

The most common shape of lightning is dendritic, in addition to balls, sheets, bands. The forms of lightning include cloudy lightning, inter-cloud lightning, and cloud-to-ground lightning.

When lightning strikes between clouds, the friction between clouds forms thunder.
