Thunder is not there, the problem of thunder?

The whole lake turned red (it was blood), and a hand was stretched out from the lake, and the girl's feet were grabbed, and she was pulled into the lake, and then, 100 kilometers away from the forest, the girl's body and clothes were found, but her head was missing, and the people opened her backpack and were frightened, and the bag was her head, and her expression was very painful, and the people who found her had abandoned her body in the forest, and then left, and since then, no one has dared to go to that forest.

If you read this post, please reply to the post immediately, and click "Bodhisattva bless", and then post this in another bar **3 copies, if not, that hand will be stretched out when you take a bath, and you will end up with that girl! Be sure that everything is true.

Thunder and lightning are the phenomenon of electrical discharge in thunderstorm clouds. The formation of thunderstorm clouds generally requires two conditions, sufficient water vapor and violent convective movements. In winter, due to the cold and dry air and weak solar radiation, convection is not easy to form in the air, so thunder and lightning are rare.

However, sometimes thunderclouds are formed in winter when the temperature is high, and thunder and lightning are generated, and rain and snow occur. Convection is particularly strong and can also form hail, which can produce the so-called "winter thunder". Knowing these reasons, it is not surprising that "winter thunder" strikes.

Lightning and thunder are common weather phenomena in summer, while snow is generally in winter, which are two completely different weather phenomena. However, as long as the weather in a certain place is suitable for both snow and thunder, these two completely different weather phenomena can occur at the same time.

In winter, when the sky is overcast and the temperature in the clouds above the sky is below freezing, the water vapor in the clouds condenses into snow. When snowflakes fall from clouds, if the air temperature near the surface layer is high, the snowflakes will melt into raindrops. Conversely, if the temperature near the ground level is low and the snowflakes cannot melt, then it will snow.

Thunderstorms are caused by strong convection of warm and moist air in local places, and the sharp rise of warm air produces violent vibrations of cumulonimbus clouds, which will accumulate a large amount of electric charge and produce lightning phenomena.

Thunder is because the water vapor in the cumulonimbus cloud produces static electricity when it is constantly moving, resulting in a voltage difference between the cloud and the ground, when the voltage difference is very large, it will break through the air, so that the air expands in an instant, heats up and glows, and the light emitted is lightning, and the huge sound emitted by the expansion ** is thunder.

Causes of thunder:

Thunder is a normal natural phenomenon like wind and rain. Thunder is also the phenomenon of the discharge of thunderclouds, in general, thunderclouds are close to the ground, and because the top of the thundercloud has a positive charge, the bottom has a negative charge. When encountering an air current, the thundercloud changes irregularly with the air flow, and the water vapor inside the thundercloud causes the air to rub against each other to produce a large amount of electric charge.

Eventually, the thundercloud was released after it could not be loaded, and the thunder and lightning were generated. That is, there are two necessary conditions for the formation of thunder and lightning: strong air currents and sufficient water vapor.

Thunder is common in summer, because in the summer when the temperature is high, a large amount of water on the ground evaporates to form a sufficient amount of water vapor, and the air on the ground is warmer to form a violent convection with the sinking cold air.

Reasons why there is rarely thunder in winter:

Judging from the conditions for the formation of thunder and lightning above, there is one thing that is really difficult to meet in winter, and that is water vapor. Winter is the driest season of the year, and the humidity in the air and on the ground is relatively low. In addition, solar radiation is the smallest season of the year in winter, so it is difficult for the air above the ground to form strong convection.

Therefore, it is true that there is very little thunder in winter.

However, less does not mean nothing. When the temperature rises during a certain period of time in winter, the content of water vapor in the air will also increase, and if strong cold air is encountered at this time, violent convection will occur. This chain sample satisfies the two necessary conditions for the formation of lightning at the same time, and thunder will occur at this time.

Because the clouds in the sky are like two positive and negative poles, when these two positive and negative pole clouds collide together, they will emit terrifying lightning at this time, and at the same time as the lightning is emitted, it will release a huge amount of heat, which will make most of the surrounding air heat and expand. At this moment, the heated and expanding air will naturally push the surrounding air that is not heated and expanded, and then cause that strong explosive vibration.

When the air around us is extremely unstable, then a strong upward convective movement will occur, and then the formation of the kind of towering cumulonimbus clouds that we are familiar with, and the clouds will also be covered with the kind of water vapor rushing up and down, which will then cause the generation of static electricity, which is also one of the necessary conditions for the formation of thunderclouds.

Precautions for thundering.

1. When thunder, the first thing to do is to close the doors and windows to prevent lightning from hitting indoor objects directly or spherical lightning from drifting into the room.

2. In case of thunderstorms, people should not stand under the bulb, and the power supply of household appliances needs to be cut off to avoid damage to electrical appliances.

3. During thunderstorms, try not to call, answer or use** the Internet, at this time, you should unplug the power supply and the metal wires that may introduce lightning such as the ** line and the TV closed circuit.

4. Leave the metal water pipe and the sewer pipe connected to the roof indoors.

Hello, thunder is a phenomenon of electrical discharge in the atmosphere. When it rains, the clouds are thick and the air is humid. At this time, when the charge is neutralized, a large amount of light and heat will be released in an instant, and the surrounding air will be heated and expanded to a high temperature of 30,000 degrees Celsius.

At the same time, the surrounding air is pushed to cause the air to vibrate, and the sound produced at this time is thunder. Electrical discharge occurs when two dissimilarly charged clouds meet or when the dissimilarly charged clouds are close to the earth.

1. I don't hate thunder, because thunder just makes lightning in the air manifest.

2. I don't hate thunder, because thunder is just to neutralize the positive and negative charges.

3. I don't hate thunder, because thunder just makes God's anger vent.

4. I don't hate thunder, because thunder just makes the brook laugh, the trees shake, and the mountain's waist rises.

5. I don't hate thunder, because thunder just makes the fire burn the clouds, like old people, like birds, like lions, slowly changing.
