How does science explain the conditions of lightning formation?
Lightning: high-intensity discharge phenomenon. Clouds are full of charged dust particles and water molecules. Some of these tiny dust particles are positively charged and some are negatively charged. The negatively charged particles are mainly concentrated at the bottom of the cloud, while the positively charged particles float at the top of the cloud. When cumulonimbus clouds are formed, the positive and negative charges between particles are separated, thus forming voltage in cumulonimbus clouds. The voltage in this cumulonimbus cloud can sometimes reach millions of volts, and eventually it will release electric energy in the form of lightning.
Lightning is a high-intensity discharge phenomenon, which occurs not only between clouds with different charges, but also between clouds and the ground. A thunderstorm not only produces a flash of lightning, but also forms many thundercloud bubbles of similar size every time. They operate independently and do not interfere with each other. Some thundercloud bubbles will gradually dissipate, while others will continue to generate. When no new thunderstorm bubbles are generated, the thunderstorm weather is over. Simply put, lightning is the light and brightness produced when the temperature rises suddenly in the process of converting electric energy into light and heat.
Thunder: the rumble of thermal expansion. Every time after lightning, thunder will follow, which is the result of lightning instantaneous high temperature. Because the air is heated and expanded, the generated air pressure will spread in the form of sound waves and reflect back and forth between the cloud and the ground, thus producing thunderous thunder.
/kloc-People within 0/5 to 20 kilometers can hear thunder, and you can also judge the distance between lightning and you by thunder. Since the speed of sound propagation in the air is about per hour 1224 km, which is equivalent to 340 meters per second, when you see lightning, start counting until you hear thunder, and multiply the counted seconds by 340 to get the distance from lightning to the ground. If you feel that lightning and thunder happen almost at the same time, it means that they are close to you.
Anecdote about lightning: Is it easier for lightning to hit people? You don't need to worry too much about lightning at ordinary times, but you need to pay attention to occasional lightning strikes and hurricanes caused by lightning. Sometimes when lightning strikes, people are just outdoors. For the sake of safety, it is safer to hide indoors quickly.
Death from lightning strikes occurs from time to time, but not all people who are struck by lightning will be in danger. According to statistics, thousands of people are killed by lightning every year in the world, and the number of injured people is 5- 10 times of the death toll. This is because most lightning current does not flow through the human body, but flows away from the skin surface. Therefore, most people who are injured by lightning are greatly frightened and have symptoms such as trance, temporary deafness and visual impairment. At the same time, lightning will leave a fernlike scar on the victim's skin surface.
80% of the people killed and injured by lightning are men. This is not a special phenomenon, but a simple probability problem. Men are usually more likely to stay outdoors and be struck by lightning than women.
In the traditional culture of China, Leigong Dian Mu in the traditional culture of China, the image of Leigong Dian Mu is actually the natural worship of the ancient ancestors for the lightning phenomenon. In ancient times, the climate changed abnormally, and lightning sometimes destroyed trees and hurt people and animals. The ancients thought it was Leigong who was angry, so they were afraid and worshipped him. There are many images of Lei Gong. In The Classic of Mountains and Seas, it is said that Leize has a leading Raytheon. It is said that Fuxi's mother stepped on the big footprints left by him and gave birth to Fuxi. The image of Raytheon is half man and half dragon, which is related to Longteng's view of the sky. There is a drum around his waist, and when it rings, it will give off thunder.
Dian Mu is also known as the lightning queen and the golden virgin. Dian Mu's belief can be said to be different from that of Lei Gong. In the early days, Lei Gong controlled the power of thunder and lightning, so it was also called? Uncle Lei Gong? Later, according to the idea of the opposition of Yin and Yang and the pairing of men and women, people separated the electric father from Lei Gong, and his gender became a woman, that is, Dian Mu. She has a mirror in her hand, and images often flash. Thor Dian Mu often appears with Storm God.
The above explains the reasons for the formation of lightning from the scientific principle, and the natural worship of lightning in ancient times due to the lack of scientific knowledge.
