What are the different types of lightning? What are the types of lightning?

Lightning, in atmospheric science, refers to the phenomenon of strong electrical discharges in the atmosphere. According to the location of its occurrence, it can be divided into three types of discharge: in the cloud, between clouds or between clouds. The electrical discharge of lightning usually produces lightning or electric light.

When the amount of electric charge reaches a certain level, which is equivalent to the voltage between the clouds or between the clouds and the earth, it will cause an electric discharge because the local electric field strength reaches or exceeds the electrical breakdown strength of the air under the current conditions. The electric power in the air is rapidly heated and expanded by the action of electric discharge, and is compressed into plasma due to the expansion, which in turn produces the special component of lightning (the sound of shock waves). At present, the specific process of discharge is not well understood, and it is generally considered to be similar to the phenomenon of long gap breakdown.

Thunderstorms are common during summer thunderstorms. Its occurrence is related to the intensity of the movement of the air flow in the clouds, and in the summer, the movement of the air flow is strong and produces more charges. There is information that thunder and lightning, i.e., thundersnow, can also occur when it snows in winter, but the probability of occurrence is quite small.

Discharges in clouds account for the vast majority of lightning, and discharges between clouds and ground are the main forms of impact on human production and life. The current of lightning is very large, and its peak can generally reach tens of thousands of amperes, but its duration is very short, generally only a few tens of microseconds. So the energy of the lightning current is not as great as imagined.

However, the power of lightning current is very large, and the damage to buildings and other equipment, especially electrical equipment, is very huge, so it is necessary to install lightning rods, lightning arresters, etc. to protect the safety of these buildings and equipment to a certain extent.

Thunder, in meteorology, refers to the sound waves degenerated by the shock wave generated by the rapid expansion of the lightning channel, which is manifested as a rumbling sound that accompanies the occurrence of lightning phenomena. Because sound and light travel at different speeds in the atmosphere, one can determine the distance at which lightning occurs by calculating the time interval between them. In the air, the speed of sound is about 340 meters and seconds, so lightning occurs about every 3 seconds at a kilometer (or 5 seconds a mile).

A lightning strike is actually a flash of lightning, but the power is relatively large, some buildings will collapse, trees will break, and people and animals may be killed or injured. In ancient China, lightning strikes were believed to be related to heavenly punishment, such as doing unfilial deeds, and the heavenly prince was furious and electrocuted the suspect to death as punishment. To prevent lightning strikes, a lightning rod directs the lightning to the ground wire.

According to the shape and characteristics, lightning can be divided into 7 types: linear lightning, ribbon lightning, sheet lightning, rocket lightning, thermal lightning, bead lightning and ball lightning. Ball lightning is also known as ball lightning or electric lightball.

Types of lightning.

Ordinary lightning that zigzags and forks are called dendritic lightning. A strip of lightning is called a strip of lightning when the wind blows to both sides of the channel, so that there appear to be several parallel lightning bolts. Two branches of lightning if they appear to reach the ground at the same time are called forked lightning.

When lightning flashes between the yin and yang charges in the clouds, and the sky of the whole region is brightened, it is called flake lightning.

Lightning that does not reach the ground, that is, lightning in the same cloud layer or between two clouds, is called intercloud lightning. Sometimes this rampant lightning will travel a distance and land on the ground many kilometers away from the storm, which is called a "thunderbolt on a sunny day".

The electrical effects of lightning sometimes create a halo-like red light around tall, pointed objects. Usually in stormy seas, a fiery red light can be seen around the ship's mast, and people borrow the name of the seafarer's patron saint and call this lightning "St. Elmo's Fire".

1. Ordinary lightning: also known as linear lightning or fork lightning, it is a cloud-to-ground, cloud-to-air, cloud-to-cloud or intra-cloud discharge.

2. Flake lightning: lightning that has no shape and covers a wide area.

3. Lightning does not always strike the ground, sometimes it is a cloud-to-cloud discharge.

4. Banded lightning: Ordinary lightning is offset by crosswinds, making lightning look like parallel, continuous lightning strikes.

Strike Protection. 1. Don't stand under a big tree.

2. Don't let yourself be the tallest object around.

3. Put down all metal objects. Don't ride a bike.

4. Do not use **, water pipes or electrical appliances that need to be plugged.

5. Keep away from doors, windows, heating stoves, stoves, and chimneys.

6. The safest place in the house is the largest room downstairs.

7. Highland security lightning rod.
