Why does it have to thunder on a rainy day? Why does it thunder on a rainy day?

Why does it rain.

As rivers, rivers, lakes, and seas are exposed to the sun, water becomes 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 currents of air in the air that are constantly moving. There is a direction to these air currents.

Running up, some running down, in different directions, at different speeds, some fast, some out.

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 charge repels each other, it is positive and negative.

The charges are gathered at the ends of the cloud. The faster the air moves, the thicker the clouds, and the more electricity is carried. Cumulus clouds carry electricity reached.

To a certain extent, it will pass through the air and neutralize the two charges. Because electricity generates heat when it passes through the air, it makes it empty.

The gas expands rapidly, resulting in a loud noise, which is called a 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 from ** when there is something protruding from the ground, so when we are in the wilderness, we can't.

Take shelter from the rain under tall trees.

Not all rainy days are thunderous, and there is usually no thunder when it rains in autumn and winter.

Because Lei Gong and Dian Mu are a good couple.

Thunder and lightning will occur on rainy days because when the air is extremely unstable, it is easy to have a strong upward convective movement, and the formation of towering cumulonimbus clouds, the clouds are filled with water vapor running up and down, static electricity will be generated, the upper and lower ends of the cloud will produce electric charges, and the air will expand in an instant** Thunder, and the electric spark emitted is lightning.

Why thunder and lightning when it rains.

When it rains, some of the clouds in the sky are positive and some are negative. When two clouds collide, lightning strikes, and at the same time emits a lot of heat, heating and expanding the surrounding air. The air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration, which is thunder.

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.

Lightning is a phenomenon of intense electrical discharge between clouds, between clouds and the ground, or between parts of the cloud. 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, and the positive charges run towards trees, hills, the tops of tall buildings, and even the human body, reaching down and getting closer to the ground.

Eventually, the negative charge of the cluster base finally overcame the barrier of air and connected, and a huge electric current surged along the conductive airway from the ground to the clouds, and lightning was generated.

<> thunder is a phenomenon of electrical discharge between clouds with a different charge or between clouds and the earth, and when it rains, the clouds in the sky have positive poles and negative poles. When two clouds collide, lightning strikes, and at the same time emits a lot of heat, heating and expanding the surrounding air. The air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration.

This is thunder.
