Which color of lightning is the most powerful? What color is thunder and lightning

Black lightning is the most powerful. They are silent and invisible, and are produced by molecular aerogel aggregates, which are heated, charged substances that can easily be transformed into ball lightning, which is extremely dangerous. Black lightning and ball lightning are similar, general lightning protection facilities such as lightning rods, lightning balls, lightning nets, etc., can not protect black lightning, so it often reaches the vicinity of oil storage tanks, gas storage tanks, transformers, and explosives depots with extremely strict lightning protection measures, which is extremely dangerous, so it must not be approached.

Black lightning is the most powerful. Black lightning is different from ordinary lightning, it is silent and invisible, black lightning is produced by molecular aerogel aggregates, and these aggregates are heated charged substances, which are very easy to ** or turn into ball lightning, which is extremely dangerous.

Black lightning is similar to ball lightning, and general lightning protection facilities such as lightning rods, lightning balls, lightning nets, etc., cannot protect black lightning; Therefore, it often reaches the vicinity of oil storage tanks, gas storage tanks, transformers, and explosives depots with extremely tight lightning protection measures very smoothly, and it is extremely dangerous, so it must not be approached.

Severe convective weather is very frequent in summer, among which thunderstorms and thunderstorms are the most active, and if precautions are not taken, they may cause certain harm.

Thunder at the time of lightning comes in several colors

The color of lightning is mostly white, and the red and green shapes are mostly dendritic, but there are also pearls and rockets. Lightning is an electric arc discharge that emits white light and contains a large amount of ultraviolet light, giving it a purple appearance.

The color of light is only a part, and the red color mainly comes from the chemical change of some gases in the air under the action of strong light, resulting in colored gases.

Blue and white light is the light of different waves seen by the naked eye, when the cloud movement cave liquid is intense, the fire light - that is, the lightning energy is very large, it ionizes the air to produce purple light with long and short points of energy and high energy, and vice versa, it is red light.

The most common color of thunder and lightning is white, but there are also red and green, and the shape is mostly dendritic, but there are also pearls and rockets. Lightning is an electric arc discharge that emits white light and contains a large amount of ultraviolet light, giving people a purple color due to the object.

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, and sometimes hail and tornadoes.

In the tip discharge phenomenon, during the discharge process, the energy released by the huge collision generated by the high-speed opposite motion of the huge charged cloud, coupled with the energy released by the huge charge discharge, is superimposed to produce a huge bridge potato, accompanied by a strong flash and a huge thunder.

There are four types of lightning: direct lightning, electromagnetic pulse, spherical lightning, and cloud flash.

1) Direct lightning strike.

Direct lightning strikes are formed by electrical discharges between clouds and ground protrusions. Direct lightning strikes can injure and kill people and animals in an instant. Huge lightning currents flow into the ground, resulting in extremely high ground voltages at the lightning strike point and the metal parts connected to it, which may directly lead to electric shock accidents involving contact voltage or step voltage.

2) Spherical mines.

Spherical lightning is a spherical, reddish or extremely bright white fireball that travels at a speed of about 2 ms. Spherical mines can penetrate into the room through doors, windows, chimneys and other passages, which is extremely dangerous.

3) Lightning induction, also known as induction lightning.

There are two types of lightning induction: electrostatic induction and electromagnetic induction. Electrostatic induction is caused by a thundercloud approaching the ground and inducing a large amount of anisotropic charge on top of a ground protrusion. When the thundercloud is discharged from other parts, the charge at the top of the protrusion loses its restraint and propagates extremely quickly along the protrusion in the form of lightning waves.

Electromagnetic induction is caused by a powerful magnetic field caused by a large lightning current that changes rapidly in the surrounding space after a lightning strike. This magnetic field can induce high voltages on nearby metal conductors, causing secondary discharges to the human body and thus damaging electrical equipment.

4) Lightning intrusion waves.

Lightning shock waves are lightning waves that are rapidly propagating along or in pipelines due to impulse voltages generated on overhead lines or on metal pipes in the air as a result of lightning strikes. Its propagation velocity is 3 108m s. Lightning can destroy the insulation of electrical equipment, causing high voltage to flow into low voltage, causing serious electric shock accidents.

For example, during a thunderstorm, the indoor electrical equipment is suddenly damaged or damaged, and a person is suddenly electrocuted to death when using electrical appliances or playing in the house.

Types of lightning:

Burst lightning.

There are four types of lightning: direct lightning, electromagnetic pulse, spherical lightning, and cloud flash. Among them, direct lightning and spherical lightning will cause harm to people and buildings, while electromagnetic pulse mainly affects electronic equipment, mainly caused by induction; Cloud flashes are the least harmful to humans because they occur between two clouds or on both sides of a cloud.

Direct lightning is to gather a lot of electric charges on the cloud, and a large number of electric charges have to find a channel to vent, sometimes it is a building, sometimes it is an iron tower, sometimes it is a person in an open place, so these people or objects become a channel for the discharge of electric charges, and the person or building is injured. Direct lightning is the most powerful lightning, while spherical lightning is less powerful than direct lightning.

The law of lightning activity:

1 The general conditions for lightning activity are as follows:

1) Geological conditions: When the relative value of soil resistivity is small, it is conducive to the rapid accumulation of electric charges. Places with low local resistivity are susceptible to lightning strikes; Places with sudden resistivity changes and underground conductive deposits are susceptible to lightning strikes; In fact, the resistivity of the grounding grid will increase the probability of lightning strikes.

2) Topographic conditions: the direction of the valley is consistent with the wind direction, and the wind outlet or downwind valley is prone to lightning strikes; There is a high probability that the slopes of the mountains near the lake or sea will be struck by lightning.

3) Ground conditions: It is conducive to the establishment of a good discharge channel between thunderstorm clouds and the earth. isolated buildings in open spaces, tall buildings in complexes that are susceptible to lightning strikes; Large trees, receiving antennas, and transmission lines in mountainous areas are susceptible to lightning strikes; In line with the characteristics of tip discharge, the probability of lightning strikes will also increase after the base station tower is completed.

2 Based on engineering experience, the following sites are likely to have a high probability of lightning damage:

1) The place where the soil resistivity R10 at a depth of 10m has a sudden change.

2) At the junction of rocky mountains, paddy fields and rivers, at the boundary of mineral deposits, at the boundary of mountains and forests, and at some geological fault zones.

3) The slope of the mountain or the windward slope facing the vast water.

4) Higher, isolated mountain tops.

5) Locations where lightning damage has occurred repeatedly in the past.

6) Isolated towers and cables, near towering buildings and other grounding protection devices.

Lightning is divided into bai direct strikes.

Induction thunder du and ball thunder.

Direct lightning is when a charged cumulus cloud approaches the DAO ground to a certain extent.

Strong response to a strong discharge with a ground target. Each discharge of direct lightning includes three stages: pilot discharge, main discharge, and afterglow. About 50 percent of direct lightning strikes have a repetitive discharge characteristic. Every lightning strike has.

Three or four shocks to dozens of impacts.

Induction lightning is also known as lightning induction, which is divided into electrostatic induction lightning and electromagnetic induction lightning. Electrostatic induction lightning is due to the charge cumulus inducing a large number of charges on the top of overhead line wires or other conductive protrusions, after the charged cumulus and other objects are discharged, the induced charges lose their binding, in the form of high-current, high-voltage shock waves, along the propagation of wire wires or conductive protrusions. Electromagnetic induced lightning is due to the high induced electromotive force generated by a rapidly changing strong magnetic field in the surrounding space when lightning is discharged.

Ball thunder is a fireball of red, orange, white, or other colors of light formed when lightning is discharged. From an electrical point of view, the ball mine should be a mass of charged gas in a special state.

In addition, both direct and induced lightning can produce lightning shocks that propagate rapidly along the lines or pipelines in both directions of the overhead line or on the aerial metal pipeline.

Types of lightning:

Lightning is divided into direct strike lightning, induction lightning, and ball lightning.

An important factor influencing the color of lightning is temperature. There's a law of physics that says that light starts orange at about 1,000 degrees Celsius, and as the temperature rises, the color shifts to blue. This is also the law of the common existence of luminous colors of high-temperature objects, from red carbon blocks to incandescent lamps to purple electric welding.

The gas is ionized at high voltages, and in the collision between the charged particles and the gas atoms, the excess energy is emitted in the form of light. Because of the different molecular structures of gases, small structural differences often cause obvious differences in the frequency of light, resulting in various colors of light. For example, neon signs, flame reactions and other colorful colors are caused by this effect.

According to folklore, blue lightning indicates hail, white lightning indicates dry weather, yellow lightning is caused by dust, and red lightning indicates that a downpour is likely. There is some truth to this statement, because dust and gas particles can scatter and absorb light, resulting in different colors.
