What is Thunder What is the difference between lightning and electricity?

Thunder and lightning is a majestic and somewhat intimidating electrical discharge phenomenon accompanied by lightning and thunder. Thunder and lightning are generally generated in cumulonimbus clouds with strong convection, so they are often accompanied by strong gusts of wind and heavy rain, sometimes hail and tornadoes. The top of the cumulonimbus cloud is generally high, up to 20 km, and the upper part of the cloud often has ice crystals.

Processes such as the attachment of ice crystals, the breaking of water droplets, and the convection of air cause electric charges to be generated in the clouds. The distribution of charges in the cloud is more complex, but in general, the upper part of the cloud is dominated by positive charges and the lower part is dominated by negative charges. 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 will be generated, which is our common lightning phenomenon. The average current of lightning is 30,000 amps, and the maximum current can reach 300,000 amps. The voltage of lightning is high, about 100 million to 1 billion volts.

A moderate thunderstorm can reach 10 million watts, which is equivalent to the output of a small nuclear power plant. During the discharge, due to the sudden increase in temperature in the flash channel, the volume of air expands sharply, resulting in a shock wave that causes a strong thunderclap. When a charged thundercloud comes close to a protrusion on the ground, a violent discharge occurs between them.

At the site of the lightning discharge, there will be a strong flash of light and a roar. This is the lightning and thunder that people see and hear. Satisfied.

Naturally, thunder and lightning are generated in cumulonimbus clouds with strong convection, so they are often accompanied by strong gusts of wind and heavy rain, and sometimes hail. The second is the secondary effect of lightning, that is, the electrostatic induction and electromagnetic induction generated by the lightning current.

Thunder and lightning is a kind of discharge phenomenon, which is a discharge phenomenon caused by the collision of a positively charged cloud and a negatively charged cloud. The electricity emitted is lightning, lightning has huge energy, can destroy trees, buildings, and can also hurt human beings, so in ancient times when science was not developed, thunder and lightning were called the wrath of God.

Thunder and lightning is an extremely majestic natural phenomenon that occurs in the atmosphere, it is often accompanied by rainfall, and occasionally thunder on sunny days, commonly known as "thunderbolt on a sunny day".

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. As a result of the movement, a heavier substance with the same charge will reach the lower part of the cloud (usually a negative charge), and a lighter mass substance 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, which are formed when the air between the charged centers of the opposite sex is broken down by its strong electric field"Inter-cloud discharge"(i.e. lightning).

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 leader downward, 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.

It is said that thunder and lightning are used to punish bad people.

It's two clouds with the same pole [like the two poles of a battery] that collide and produce lightning.

1. The principle is different.

The former arises in cumulonimbus clouds with strong convective development, so they are often accompanied by strong gusts of wind and heavy rain, and sometimes hail and tornadoes;

The latter is a pulsed discharge phenomenon in the atmosphere, consisting of multiple discharge pulses, with short intermittent times of only a few hundredths of a second.

2. The characteristics are different.

The former emits lightning when the clouds collide together, and at the same time emits a lot of heat, which heats up and expands the surrounding air. The air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration;

The length of the latter may be only a few hundred meters, the shortest is 100 meters, but the longest can be several thousand meters. Its temperatures range from 17,000 to 28,000 degrees Celsius, and the air swells violently along the way.

3. The nature is different.

The former, as a powerful sound, has the direct action of electric current and overpressure or kinetic action, as well as the action of high temperature;

The latter, as a form of energy that can be easily transmitted, can be used for applications that are increasing dramatically day by day.

Difference Between Thunder and Electricity: Thunder is sound, while electricity is light.

1. Thunder and lightning are a natural phenomenon, a discharge phenomenon produced by the encounter between positive and negative charges when the clouds in the sky carry a large amount of positive and negative electricity.

2. We saw lightning first because the propagation speed of light is 3600 kilometers per second, which is the fastest, and then we heard thunder, and the sound propagated in gas, solids, and liquids, the fastest in solids, and a little slower in gases. So we see lightning first and then hear thunder.

3. During the formation of cumulonimbus clouds, some clouds have a positive charge and some clouds have a negative charge. When the charge accumulates to a certain extent, the electric field strength between the clouds of different charges, or between the clouds and the earth, can penetrate the air and begin to discharge freely, which we call it"Pilot discharge"。

The cloud-to-ground pilot discharge is a gradual development of the cloud leaping towards the ground, and when it reaches the ground, it will produce a reverse conductive main discharge from the ground to the cloud. In the main discharge stage, due to the violent neutralization of the opposite charge, a large lightning current will occur, followed by strong lightning and loud noises, which will form lightning.

The characteristics of lightning and electrical discharge are:

1. Large current: The lightning current discharge current is large, and the amplitude is as high as tens to hundreds of kiloamperes.

2. Short discharge time: The discharge time is extremely short, only about 50-100 s, and the steepness of the wave head is high, up to 50ka s, which belongs to high-frequency shock waves.

3. High voltage: The voltage generated by lightning induction can be as high as 300-500K.
