When I was a child, I often encountered thunder, why haven t I experienced thunder in recent years?

In fact, there is a phenomenon of thunder every year during the thunderstorm season. When I was a child, I encountered it because I was very idle at that time, I often played outside, and when I encountered rainy weather, I preferred to play outside, and when I grew up, I rarely had time for outdoor activities. Because of work and life, everyone is under a lot of pressure, and it is almost three o'clock every day, so it is rare to encounter thunder.

In recent years, the rainfall has decreased in some areas, so there is very little thunder, due to the anomaly caused by climate change, many natural phenomena when I was a child, and many animals and plants, are not seen now.

Yes, I just think that when I was a child, I often encountered thunder and was scary, but in recent years, there has been less thunder, which may be the reason for the change of celestial phenomena, just like climate change, and now the climate in winter is much warmer than in the past.

You are indiscriminate, my farmers work in the field every day, what is the pressure, I just said that this year there is less thunder and umbrellas than in previous years, what is the reason for this, it rained a few years ago, as long as it was cloudy, lightning and thunder, this year there are few lightning and thunder, and it has nothing to do with the pressure,

It is caused by changes in climate.

During the rainy season, there will be thunder and lightning.

Women, if you have such qualities, then you will never lack people who love you. I'm Crystal Zhiqiu, you have a story, come to me. There is a saying that many women have said to me: when I was young, I didn't listen to my parents, and I was crazy about it.

There are many currents of air in the air that are constantly moving. Some of these currents run upwards and some downwards, in different directions and at different speeds, some are fast and 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 charges are repulsive, the positive and negative charges are concentrated at the opposite ends of the cloud. The faster the air moves, the thicker the clouds, and the more electricity is carried.

When the electricity carried by the cumulus clouds reaches a certain level, it will pass through the air and neutralize the two charges. Because when electricity passes through the air, it will heat up, causing the air to expand rapidly, thus making a loud noise, which is the 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 electricity from the ground if there is something protruding, so when we are in the wilderness, we cannot go to the tall trees to take shelter from the rain. 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 thunder is rare in China, but it often occurs in the winter in Toronto, Canada When the air is extremely unstable, it is easy to have a strong upward convective movement, and the formation of towering cumulonimbus clouds, the clouds are filled with water vapor running up and down, static electricity will be generated, 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** , heat and glow, glow is lightning, expansion ** makes a huge sound is thunder.

Thunder is a natural phenomenon that is usually caused by an imbalance in the distribution of electric charges in the atmosphere. When an electric charge is concentrated on the magnetic field line of the earth, an electric field is generated, which causes the phenomenon of electric discharge, which is called lightning.

During thunderstorms, lightning is the dominant phenomenon. Lightning is a high-energy electrical discharge process that can generate up to thousands of volts of electricity in an instant. When lightning occurs, the gas molecules in the atmosphere are ionized, resulting in the production of a large number of electrons and ions in the air, forming a conductive system of Solo's.

These electrons and ions move through the conductive system, creating an electric current that produces thunder and flashes of light.

In addition, lightning can also cause various disasters, such as fires, and people. Therefore, we need to understand the formation mechanism and preventive measures of lightning to reduce the occurrence of lightning disasters.

Thunder's imagination is that some clouds in the sky have positive poles and some negative poles, and when the two clouds collide together, they will emit lightning, and at the same time release a lot of heat, causing the surrounding air to heat up and expand. The air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration.

This is thunder.

The answer is because of the vigorous convective movement. When a cumulonimbus cloud is formed, the cloud is filled with water vapor rushing up and down, which generates static electricity, and 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 will have 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, and the expansion makes a loud sound is thunder.

The process of clouds drifting in the sky rubs against the air and generates static electricity. When static electricity accumulates to a certain level, the voltage breaks through the clouds"Breakdown"voltage, it will break through the clouds and discharge (or the air between the clouds and the ground).

The clouds collide, the positive and negative poles meet, just like the sound you make when you take off your sweater.

It's big, though, so it's loud!

Because the positive and negative ions in the clouds are in contact with each other.

A spark discharge phenomenon is generated. So lightning was born.
