Why does the sky thunder and lightning?

Question 1: How to dominate in the true soul? Really? The ability balance of the soul-serving role is still good, but it is not complementary. I just feel that Wang Hu is not very strong. Maybe this is a defect.

Question 2: Why is there lightning and thunder in the sky? There are clouds with two kinds of charges in the sky, one is positively charged and the other is negatively charged; When they are moving, the sound produced by mutual friction is the thunder we hear, and the electron flow released by the electrons formed by the collision of positive and negative electricity is the lightning we usually see.

Question 3: Why does the sky thunder and lightning? It is a discharge phenomenon caused by the meeting of two big clouds with different charges: there are positive and negative charges between the clouds.

Question 4: Why is there lightning in the sky? The rain in the sky comes from the clouds in the sky, but it is actually the condensation of water, which comes from the evaporation of water vapor on the ground. When the water droplets in the cloud reach a certain level, that is, they cannot be supported by the rising airflow, the water droplets (possibly ice droplets and snowflakes) will fall to the ground, that is, the rain (hail and snow) we see. The evaporation of water vapor will happen at any time, but it won't rain at any time. In the air, when the temperature is high, the amount of water vapor that can be accommodated is large, and when the temperature is low, the amount of water vapor that can be accommodated in the air is small. When air moves from high temperature to low temperature, water vapor will change from unsaturated to supersaturated and condense into water droplets. When the weight of water drops exceeds the buoyancy of air, it will rain. For example, in the summer afternoon, due to the strong evaporation, rise and condensation of water vapor, showers are formed; Cold air meets southeast hot and humid air to form frontal rain, and so on. As rivers, lakes and oceans are exposed to sunlight, water becomes steam. When the water vapor rises, it becomes small water droplets or ice crystals, and the airflow below constantly transports the water vapor into the clouds. Small water droplets and small ice crystals in the cloud collide with each other in motion, and the volume will increase. The water droplets in the lower layer of the cloud gradually get bigger. After the ice crystals in the upper layer of the cloud increase in volume, they will fall between the water droplets in the lower layer of the cloud, and the water droplets will become larger and larger. When these water droplets are too big for the updraft to drag, it rains. -Lightning is a common natural phenomenon in summer. Do you know what lightning is? It is static electricity generated by the friction between clouds moving at high altitude. When static electricity accumulates to a great extent, it will discharge each other, thus forming the lightning that we see piercing the sky. Thunder is actually the vibration produced when lightning penetrates the air. A lightning bolt is usually several hundred meters to several thousand meters, so the sound from this lightning bolt will reach our ears in a few seconds or more (the speed of sound propagation in the air is 340m/s). And thunder will reflect back and forth between clouds, so we won't hear thunder until after lightning, and thunder will "rumble" for a long time.

Question 5: Why do natural phenomena like thunder and lightning appear when it rains? To put it simply: when it is going to rain, there will be large cumulus clouds in the sky. These clouds are electrostatic. When two oppositely charged cumulus clouds approach, they will discharge. This is the lightning we see. Because of the high current and high temperature. This makes the surrounding air rapidly expand and explode, thus generating lightning.

Question 6: Why do electric balls appear in the sky when it thunders? Spherical lightning, commonly known as rolling thunder, is a spherical lightning ball. This is a real physical phenomenon, not an energy cannon of science fiction or comic series. This phenomenon was recorded as early as 1838. Scientists have studied it for 160 years and published thousands of related reports and more than 2,000 scientific papers. However, we still have no reasonable explanation for this phenomenon, but it is not credible to say that it can cross any object.

Spherical lightning usually appears in thunderstorm weather. It is very bright, slightly spherical and about 20 to 50 cm in diameter. Usually it lasts only a few seconds, but there are also 1-2 minutes. Even more amazing, it can move independently and slowly in the air. Some witnesses said it would follow metal objects, such as telephone lines, but most people said its path was uncertain. Most witnesses said it moved horizontally. In its short life of a few seconds, its luminosity, shape and size remain unchanged. It has appeared in open spaces, closed rooms and even airplane cabins! There are signs that it is closely related to lightning between clouds and the ground (that is, common ordinary lightning), and witnesses say it will form or disappear after ordinary lightning. Spherical lightning may explode violently, or it may suddenly disappear quietly. In terms of color, opinions vary and there is no consistent description.

Spherical lightning is destructive. It can not only destroy the glass window, but also make the outer layer of the wall peel off. It also caused human and animal casualties, but due to insufficient information, the real cause of death has not yet been known. There is no evidence that ball lightning will destroy trees, which is slightly different from ordinary lightning. Spherical lightning can hardly be destroyed Someone once used a rifle to shoot ball lightning, but it didn't work.

Because of the low frequency of spherical lightning, it is difficult for scientists to make systematic observation, and no one has taken high-quality photos for scientific research so far. Theoretically, some people think it is a hot air mass or a vaporized element, such as carbon, sodium valve or copper. Although this theory can explain some characteristics of spherical lightning, it can't explain why it can form in the aircraft cabin. In addition, there are many different theories, such as plasma, ions, charged dust, and water with an outer electron layer, but none of them can fully explain this scientific unsolved case. If you have ever seen or taken photos of ball lightning, be sure to record all the information! That will be very valuable research data.

Spherical lightning is mysterious because it is not common. Its ethereal whereabouts, changeable colors and shapes, and its great destructive power to stop time fascinate human beings. Therefore, as early as ancient Greece, people began to pay attention to this strange natural phenomenon.

Question 7: Why does the sky thunder, lightning and rain? Thunder is caused by the collision of two or more huge dark clouds. Lightning is caused by friction after dark clouds collide. Rain is the condensation of water vapor in the dark clouds after the temperature drops, and then it is affected by gravity, and finally it becomes a cloud to cause rain.

Question 8: Why does the sky twinkle tonight? But it doesn't mean that thunder doesn't happen. Where there is lightning, there must be thunder, and the propagation law of thunder is the same as that of water waves. When the water waves are far away, it will be close to calm, and so will thunder. If you can't hear the thunder, then this lightning phenomenon happens at a distance from us. In the process of propagation, the thunder will spread outward. So there was no thunder.

Question 9: Why does it thunder? When it rains, some clouds in the sky are positively charged and some are negatively charged. When two clouds meet, they will discharge, emit bright and bright lightning, and at the same time release a lot of heat, which will make the surrounding air heated, expand and make a loud noise. This is thunder.

Introduction:

According to experts' analysis, lightning is a discharge phenomenon in thunderstorm clouds. Thunderstorm clouds generally have two conditions, sufficient water vapor and strong convection. In winter, because the air is cold and dry, the solar radiation is weak, and convection is not easy to form in the air, so lightning is rare. But sometimes when the temperature is high in winter, it will form thunderstorm clouds, leading to lightning and rain and snow. Convection is particularly strong, and it can also form hail, which will produce the so-called "winter thunder" weather phenomenon. Since the middle of 5438+ 10, the warm and humid air flow has been extremely strong, and the temperature is obviously high. On June 5438+04, the highest temperature reached 22. 1℃, the highest in the same period in history. On June 5438+07, the strong cold air in the north went south and the two met. It not only snowed, but also thundered. Knowing these reasons, it is not surprising that it thunders in winter.

Reason:

It is reported that one night in the early spring of 1970, the north wind roared in the middle and lower reaches of the Yangtze River in China, and it was snowing with rare goose feathers. Suddenly, there was lightning and thunder in the sky, which is a rare weather phenomenon and makes people feel strange. There is also a phenomenon of heavy snow accompanied by thunder in the Lantern Festival in western Shandong. So, why does it thunder on snowy days?

Lightning and thunder are common weather phenomena in summer, while it usually snows in winter. These are two completely different weather phenomena. However, as long as the weather in a certain place has the conditions of snow and thunder at the same time, these two completely different weather phenomena can appear at the same time.

In winter, the sky is overcast, the temperature of the upper clouds is below zero, and the water vapor in the clouds condenses into snow. When snowflakes fall from the clouds, they will melt into raindrops if the air temperature near the ground is high. On the contrary, if the temperature near the ground is low and the snow cannot melt, it will snow.

Thunderstorms are caused by strong convection of warm and humid air in some places. The sharp rise of warm air produces the violent vibration of cumulonimbus clouds, which will accumulate a lot of charges and produce lightning.

The formation of lightning:

As we all know, the lightning in thunderstorm season is the same as the ionization breakdown of insulating materials in high voltage electric field. In thunderstorm weather, the high-voltage electric field formed by charged clouds is very strong. Usually, this is the case when charged clouds discharge to the earth. Clouds have a high potential in the positively charged region, while the earth has a low potential in the negatively charged region. Air is originally non-conductive, but under the action of strong electric field force, the outermost electrons of gas nucleus will be excited by electric field force to make a transition and form charged ions. The atoms that gain electrons are called negative ions, and the atoms that lose electrons are called positive ions. Under the action of electric field force, charged ions can form electron flow. In addition, the electrons of the insulator are strongly influenced by the gravitational field of the nucleus, which can also be called the binding force of the nucleus on the electrons. In the general external electric field, the peripheral electrons are in a large inert state, and it is difficult to excite the orbit to become charged ions. If the applied electric field force exceeds the binding force of its insulator to the electron, that is, the excited state of the electron, then its insulator will form what we often call a breakdown state and participate in conduction. Among natural substances, natural mica is the most conductive inert substance, followed by glass, ceramics, plastics and so on. Air is a general insulating medium, and the free inertia of electrons around the nucleus of pure single gas is also very strong. However, the composition of space gas is not pure, and it is also doped with other material particles or water molecules, which is easy to form ionic States formed under low electric field. Dielectric breakdown ionization conduction is a common technical term in electrotechnics. In the face of the strong electric field formed in nature, the insulating medium formed by space gas is insignificant, and the voltage field of hundreds of millions of volts can easily excite electrons outside the gas core to become charged ions to participate in conduction. The breakdown of insulating medium is the ionic state of insulating substance, and the arc discharge phenomenon formed by high-voltage electric field is the optical radiation produced by the energy release formed after the electrons outside the core of insulating medium are excited freely.

Lightning is a plasma conduction state formed by the extranuclear electrons of space gas excited by electric field, accompanied by optical radiation and thermal effect. Due to the action of light and thermal radiation, the temperature of the surrounding air rises sharply, leading to thermal expansion, which in turn pushes the air to form a shock wave, that is, the sound of thunderstorm we hear. The greater the concentration of water molecules in the air, the more impurities there are, and the greater the possibility of breakdown ionization by high-voltage electric fields. & gt
