Who is the scientist who unravels the mystery of thunder and lightning!

Franklin, USA.

Benjamin Franklin was a famous American politician and scientist, as well as a publisher and printer, a journalist, a writer, a philanthropist, and an outstanding diplomat and inventor. Born in Boston, Massachusetts, in 1706, Franklin was involved in the drafting of important documents and served as U.S. ambassador to France, successfully gaining French support for American independence. He has conducted a number of experiments on electricity, and invented the lightning rod, as well as the leaky rock leak of bifocal glasses, fins, etc.

He was the first scientist and inventor in American history to achieve international fame. In order to explore electricity, he has made a famous kite experiment, and has made remarkable achievements in electricity, and in order to deepen the law of electric motion, many special terms such as positive electricity, negative electricity, conductive key retarder, battery, charge, discharge, etc. have become common words in the world. He borrowed the mathematical concept of positive and negative, and the first scientifically used the concept of positive and negative electricity to express the properties of electric charge.

He also put forward the idea that electric charges cannot be created or destroyed, and later generations discovered the law of conservation of electric charges on this basis. He was the first to put forward the idea of lightning rods, and the lightning rods created from this avoided lightning disasters and broke superstitions.

Zhang Jiao's famous words: The sky is dead, Huang Tian should be in Jiazi, and the world is auspicious and Lei Gong will help me.

1, Lei Gong. A:

Lei Gong is also known as the God of Thunder or the Master of Thunder. The god of thunder in ancient myths and legends is worshiped by Taoism as the servant god who performs the thunder law. Legend has it that Lei Gong and Dianmu are a couple.

The name of Lei Gong was first seen in "Calling the Hidden Bird Chu Ci", because Lei is the yang energy of the heavenly court, so he is called "Gong Carries the Old". It is said to have been in the form of a beast, or a ghost, or a pig, and most of them are monkeys; The back shape is like a wrestler, with an open chest and exposed abdomen, two wings on the back, three eyes on the forehead, a red monkey-like face, feet like an eagle, holding a wedge in the left hand, holding a cone in the right hand, showing the shape of wanting to hit, and several drums are hung next to the god and the morning, and there are drums under the feet. The drumming is thunder.

Able to distinguish between good and evil in the world, enforce the law on behalf of heaven, kill the guilty, and uphold justice.

In summer, the sun shoots a large stream of gas particles into the earth, heating the earth, air and water vapor, so that the air and water vapor carry enough gas molecules. When the gas particles escape with air and water vapor to the edge of the universe in the opposite direction of the earth's core, they fall behind due to the weight of the large water droplets, and at the same time, the rising gas beads compete with the core of the large water droplets for part of the gas particles, so that the large water droplets have cavitation force, that is, positive electricity. The lighter water droplets have more gas force, that is, negative electricity.

In this way, the upper layer of small water beads and clouds are negatively charged due to the more air force, and the low-altitude large water bead clouds are positively charged due to the more cavitary force, and when they are combined, the phenomenon of thunder and lightning in the air is produced.

If the heat on the earth's surface is greater and the pressure of gas particles is higher, when the gas particles escape with water vapor, the gas flow formed will also compete for part of the gas particles in the earth's core, so that the earth's core will form a cavitary force and become positively electric. At this time, all clouds have a negative potential towards the ground. In this case, the lightning phenomenon is more intense, and there is often a ground discharge, resulting in low-altitude lightning phenomenon, which causes harm to human beings.

When the gas flow escapes with water vapor, it competes for the gas particles of the large water droplets and the earth's core, and the combination of the cavity force and the gas force produces the phenomenon of thunder and lightning.

In simple terms, it is the physical effect of air breakdown caused by the strong potential difference between the positive and negatively charged clouds when they approach.

The upper part of the cloud is dominated by a positive charge, and the lower part is dominated by a negative charge. As a result, a potential difference is formed between the upper and lower parts of the cloud. When the potential difference reaches a certain level, an electric discharge is generated, which leads to the formation of lightning.

Thunderbolt is nature's ** home, and it will play his drum kit in the sky. It flips the clouds, and the clouds hit the middle like a drummer with a variety of different rhythms. In the beginning, the drum kit first made a small sound, like a soft light**.

After a while, there was a "boom" sound.

Abstract:During the formation of cumulonimbus clouds, positive and negative charges accumulate in different parts of the cloud under the simultaneous action of atmospheric electric field, temperature difference and fragmentation. When the charge accumulates to a certain extent, it discharges between clouds or between clouds and ground, which is what we see as lightning ......

People usually call the clouds where lightning occurs thunderstorm clouds, in fact, there are several kinds of clouds that are related to lightning, such as stratocumulus clouds, nimbus stratus, cumulus clouds, cumulonimbus clouds, and the most important thing is cumulonimbus clouds.

The formation of clouds is the process of condensation of water vapor in the air to a saturated or supersaturated state for various reasons. Saturation of water vapour in the air is a necessary condition for the formation of clouds, and the main ways of this are:

1) The water vapor content remains unchanged, and the air is cooled and cooled;

2) The temperature remains unchanged and the water vapor content increases;

3) It not only increases the water vapor content, but also reduces the temperature.

But for the formation of clouds, the cooling process is the most important. Process. In the process of cooling, the cooling effect caused by the upward movement is the most common.

A cumulonimbus cloud is a type of cloud that forms during a strong vertical convection. Because the ground absorbs much more radiant heat from the sun than the air layer, so the ground temperature rises more during the day, and this warming is more obvious in summer, so the temperature of the atmosphere near the ground also rises due to heat conduction and heat radiation, and the gas temperature will inevitably expand, the density will decrease, and the pressure will also decrease, according to the principle of mechanics, it will rise, and the density of the air layer above will be relatively large, and it will sink. During the uplift, the hot air expands and lowers the pressure, and at the same time exchanges heat with the high-altitude and low-temperature air, so the water vapor in the rising air mass condenses and fog droplets appear, forming clouds.

During strong convection, the fog droplets in the clouds further cool down and become supercooled water droplets, ice crystals, or snowflakes, which gradually increase with altitude. At the freezing altitude (-10 degrees Celsius), the latent heat is released due to the massive freezing of supercooled water, which causes the cloud top to develop abruptly upwards and spread horizontally near the tropopause. When the charge accumulates to the point where it is milled to the point of a balance, there will be a discharge between clouds or between clouds and ground, which is what we see as lightning.
