When will it thunder and when will it thunder?

Why does it rain As rivers, rivers, lakes, and seas are exposed to the sun, water turns into water vapor. The water vapor rises and turns into small droplets, and finally into clouds. The small water droplets or Xiaoice crystals that make up the cloud are supported by the air flow below, and the rising air flow is constantly transporting the water vapor below the cloud to the cloud.

The small water droplets and Xiaoice 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 become larger, and as the volume of the ice crystals in the upper layer of the cloud increases, the water droplets fall between the droplets in the lower part of the cloud layer, and the water droplets become larger and larger. When these droplets are so big that the updrafts can't hold them, it rains.

Why is it thundering There are many air currents in the sky that are constantly moving. Some of these currents run upwards and some downwards, in different directions and at different speeds, some are fast and some are slow. The movement of the air currents causes the cumulus clouds in the air to either rush upwards and some downwards.

The friction between clouds and clouds causes clouds to carry different kinds of charges. Since the same kind of charges are repulsive, the positive and negative charges are concentrated at the opposite ends of the cloud. The faster the air moves, the thicker the clouds, and the more electricity is carried.

When the electricity carried by the cumulus clouds reaches a certain level, it will pass through the air and neutralize the two charges. Because when electricity passes through the air, it will heat up, causing the air to expand rapidly, thus making a loud noise, which is the transport mine. If the charged cumulus cloud is relatively close to the ground, the electrostatic inductance will cause the ground to carry a different charge than the lower layer of the cloud.

When the charge reaches a certain level, the cumulus cloud will discharge to the ground, which is a landing mine that is easy to cause disasters. Generally speaking, it is easy to discharge electricity from the ground if there is something protruding, so when we are in the wilderness, we cannot go to the tall trees to take shelter from the rain.

There is no way to know the exact time of the thunder. Thunderstorms are natural conditions, but under normal circumstances, thunderstorms do not last too long, and this phenomenon rarely lasts for more than 1 hour in a row. Some of the clouds in the sky have positive poles and some have negative poles.

When two clouds collide, lightning is emitted and a lot of heat is released, causing the air to heat up and expand. The heated and expanded air pushes the surrounding air, causing a strong vibration that makes the cherry blossoms violently. This is thunder.

Thunder Introduction: Lightning is a 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, in some cases, thunderstorm clouds are formed when the temperature is high in winter, and thunder and lightning are generated, and rain and snow occur.

Convection is particularly strong and can also form hailstones, which can produce the so-called winter thunderstorms. Since the middle of January, the warm and humid airflow has been unusually strong, and the temperature has been significantly high, with the highest temperature on the 14th, the highest in the same period in history. On the 17th, the stronger cold air from the north moved south, and the two converged, and not only snow fell in the sky, but also thunder sounded.

Knowing these reasons for the liquid plexus, it is not surprising that there is thunder in winter.

Thunder in November is also winter thunder, thunder all year round, is a normal weather phenomenon, but there are fewer thunderstorms in autumn and winter. Although not common in autumn and winter, "thunder winter" weather is nothing more than a weather phenomenon.

Through long-term and detailed observation of the phenomenon of "thunder and winter", the folk have summed up the law of "thunder and snow in winter", which means that thunder in winter indicates that the air humidity is high and it is easy to form rain and snow; There is also a folk saying that "thunder strikes in winter, ten cattle pens are nine empty", which means that in winter, thunder, warm and humid air is very active, cold air is also very strong, the weather is cold, there is a lot of ice and snow, and even cattle may be frozen to death.

Thunder is summer.

There are many thunderstorms in summer, and thunder requires sufficient water vapor and vigorous convective movement, and the rain is abundant in summer, which is more satisfying. Thunder is a phenomenon of discharge in the thundercloud rain, when the positive and negative clouds come into contact with the lightning will be generated, and at the same time release a huge amount of heat to cause the surrounding air to vibrate, which further leads to the appearance of thunder, forming the common thunder and lightning in our lives.

Precautions for thundering

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

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

3. Showers should not be used. Although water pipes are generally equipotential connected to lightning grounding, lightning currents may be conductive through water currents and cause human beings**.

4. During a thunderstorm, try not to call, answer or use** the Internet, and unplug the power supply of electrical appliances, wires and TV feeders and other metal wires that may introduce lightning into the room.

5. Keep the house dry, and repair it in time when the house leaks.

6. The insulator iron feet of the power cord should be reliably grounded, and the protective ground wire in the indoor power socket should be well connected. Bonai.

7. Do not pull the wire used for drying clothes and bedding to the window or door to prevent the wire from causing lightning.

8. Do not stay in the rain for a long time without lightning protection devices or isolated pavilions and grass sheds. Be careful to avoid electrical wiring, do not stand under light bulbs, and preferably when the power is off or not in use.

Thunder is a natural phenomenon, because the cloud droplets or ice crystals in the cumulonimbus cloud increase to a certain extent, so that the electric field strength in the cloud reaches or exceeds the breakdown electric field strength of the gas, resulting in violent friction of the air inside the cloud or between the cloud and the ground, thereby generating a large amount of instantaneous heat energy, making the air volume expand sharply, causing strong ** vibration, and at the same time making the surrounding air appear extremely strong charged effect, causing lightning.

When the weather is cooler, it stands to reason that there is less chance of lightning than on a hot day, so why are thunderstorms still frequent? This is because in the summer we stay in the "greenhouse" and blow the air conditioner all day long, on the one hand, the relative humidity becomes smaller; On the other hand, when lightning occurs, there is often a random turbulence that spreads out and acts as a good conductor. In the cool autumn and winter, there are fewer conductors, and lightning strikes occur from time to time.

Thunderstorms are mostly concentrated in convective or downburst clouds with particularly strong convection, at this time, in the front and upper parts of the convective or downburst clouds, upward shock waves are often generated, and with the strengthening of convection, the shock wave gradually strengthens. What followed was a flash of lightning, and a large-scale discharge between clouds and between clouds and between clouds and the earth was generated.
