Why is rain after lightning? How does the lightning in the sky come from when it rains?

Because the eyes are in front. The ears are in the back.

Rain with lightning is called a thunderstorm, and rain without lightning is ordinary rain.

That's all about the object.

Who said, there was no lightning and it rained.

Lightning is a phenomenon of electrical discharge produced by clouds and clouds, clouds and the earth, and lightning is produced when positive electricity meets negative electricity.

Lightning is a phenomenon of intense electrical discharge between clouds, between clouds and ground, or between parts of the cloud body (usually in cumulonimbus clouds).

Usually storm clouds (cumulonimbus clouds) produce electric charges, with yin electricity at the bottom and yang electricity at the top, and also a positive charge on the ground, which follows the clouds like a shadow. Positive and negative charges attract each other, but air is not a good conductor.

When it rains, cumulonimbus clouds produce an electric charge, with a negative charge at the bottom and a positive charge at the top, and also on the ground. The positive and negative charges attract each other, and finally the positive and negative charges finally overcome the air barrier and connect.

The main reason is that there are certain ions in the air, and the collision of these ions will produce a huge amount of energy.

Because before the rain, there are a lot of clouds in the sky, which will produce a large amount of electric charges, and when these charges are connected, lightning will be formed. During the hot summer months, especially in the south, there are often sudden rainstorms. We will find that before the sudden heavy rain, there are often lightning and thunderstorms, generally speaking, lightning first, then thunder, and then heavy rain is coming.

1. Intense electrical discharges between clouds in the sky, or between clouds and the earth, during lightning on a rainy day. There are many types of lightning, such as line lightning and ball lightning. The most common is the line of lightning, which when it is strongly discharged, it is shaped like a river on a map, with a main line and many branches.

When it is about to rain, the clouds in the sky are generally thick, and these clouds will inevitably cause friction and form a large amount of electrical charge.

2. The formation principle of lightning The large number of charges generated by the friction of clouds are divided into two types, one is positive charge and the other is negative charge. The positive and negative charges are supposed to attract each other, but air is not a good conductor. The positive charge will run towards the trees, mountains, and the negative charge will stretch downwards and approach the ground.

Eventually, when the positive and negative charges overcome the obstacle and finally meet, a huge electric current phenomenon is generated, known as lightning.

3. The Hazards of Lightning and Prevention In rainy days, if you are unfortunately struck by lightning outdoors, it is a very dangerous thing and will pose a threat to people's lives. Therefore, we must take precautions in time, unless absolutely necessary, do not venture out when there is strong lightning, try to stay indoors, do not get close to metal pipes, doors and windows, etc., do not use **, do not risk packing up the clothes on the balcony.

Rain is due to the accumulation of clouds in the sky, and clouds are composed of mist water, lightning is because clouds carry a large number of positive and negative electrodes, and when they collide together, a certain current will be generated, which also forms lightning.

This is because when it rains, the clouds are relatively thick, and then the clouds will rub against each other to produce a large amount of electric charge, and the charge will be released to a certain extent to form lightning.

Lightning is the flow of air in the rain, rubbing and decomposing with water molecules, thus producing strong positive and negative electrons, these electrons meet, and lightning is produced, which is why lightning occurs on rainy days.

Staring at lightning is a natural phenomenon in which storm clouds (cumulonimbus clouds) produce electric charges, with yin electricity at the bottom and yang electricity at the top, and also a positive charge on the ground, which follows the clouds like a shadow. Because the high voltage between the two electrodes can be artificially maintained for a long time, it is difficult to replenish the charge in a thundercloud immediately after discharge. When the accumulated Xingling charge reaches a certain amount, a strong electric field is formed between different parts of the cloud or between the cloud and the ground.

The electric field strength can reach several thousand volt centimeters on average, and up to 10,000 volt centimeters in local areas. The electric field is strong enough to penetrate the atmosphere inside and outside the clouds, so that dazzling flashes of light are triggered between the clouds and the ground, or between different parts of the clouds and between different cloud masses. This is what is often referred to as lightning.

When a thundercloud moves somewhere, the middle and lower part of the cloud is a strong negative charge center, and the underlying surface opposite the cloud base becomes a positive charge center, forming a strong electric field between the cloud base and the ground. In the case of more and more charges accumulating and the electric field getting stronger and stronger, a section of air column with strong ionization of the atmosphere first appears at the bottom of the cloud, which is called the cascade pilot.

Reasons why there will be lightning when it rains:

1.Lightning is a natural phenomenon, usually a storm cloud generates an electric charge, the bottom layer is yin, the top layer is yang, and a huge electric current swells along a conductive airway from the ground to the clouds, producing a bright and dazzling flash;

2.In most cases, lightning can only be generated when the thickness of the lightning cloud layer exceeds 3 km, the upper part of the cloud is often positively charged, and the bottom of the cloud layer is negatively charged, when the electric field between the positive and negative charges is strong enough, it will penetrate the air and produce lightning;

3.Many scientists believe that falling large raindrops or ice balls carry a negative charge, and positively charged particles such as small dust particles and ice crystals accumulate in the upper part of the cloud, making the upper part of the cloud positively charged and the lower part negatively charged, creating an electric field large enough to cause lightning, which causes lightning when it rains.
