Why is it raining in the sky? 40

This is a law of nature.

When the water on the earth is irradiated by the sun's rays, it becomes water vapor and evaporates into the air. When water vapor encounters cold air at high altitudes, it condenses into small water droplets. These small droplets are small, with a diameter of only millimeters and a maximum of millimeters.

They are small and light, held in the air by updrafts in the air. It was these small droplets of water that gathered together in the air to form clouds. These small droplets of water are going to fall to the ground as raindrops.

In the early stages of raindrop formation, cloud droplets mainly rely on the continuous absorption of water vapor around the cloud body to condense and condense themselves. If the water vapor energy source in the cloud is continuously replenished and the surface of the cloud droplet is often in a supersaturated state, then this condensation process will continue, so that the cloud droplet will continue to grow and become raindrops. However, sometimes the amount of water vapor in the cloud is limited, and the supply of water vapor in the same cloud is often in short supply, so it is impossible to make each cloud drop grow into a larger raindrop, and some smaller cloud droplets have to be merged into the larger cloud droplets.

If water droplets and ice crystals coexist in the cloud, the process of condensation and bloom increase will be greatly accelerated. When the droplets in the cloud increase to a certain extent, due to the increasing size and weight of the large droplets, they will not only catch up with the slower small droplets in the process of descending, but will also "swallow" more small droplets and make themselves stronger. When the large cloud droplets grow larger and larger, and finally the air can no longer support them, they fall straight from the clouds to the ground, becoming our common rain.

Because temperature affects the form of water.

It rains in the sky because the ice crystals in the upper layers of the clouds increase in size and fall between the droplets in the lower part of the clouds, and the droplets grow larger and larger, and when they are so large that the updrafts cannot support them, it rains. Rivers, rivers, lakes, and seas are exposed to the sun, and the water turns into water vapor. The water vapor rises and turns into small droplets, and finally the empty circle turns into a cloud.

The small water droplets or Xiaoice crystals that make up the cloud are supported by the air flow at the lower side of the collapse, and the rising air flow is constantly transporting water vapor from below into the cloud.

Summary. Hello dear! The reason why it rains in the sky is that rivers, rivers, lakes, and seas are irradiated by the sun, and the water will turn into water vapor, which will rise and turn into small droplets, and finally become clouds. The small water droplets and Xiaoice crystals that make up the cloud are supported by the air flow below, and the updraft also continuously transports water vapor from below into the cloud; The small water droplets and Xiaoice crystals in the cloud collide with each other in motion, and the volume will increase and fall.

Dear, for you to expand Chahu inquired: rain is a natural scene, is the earth's water irradiated by the sun's rays, it becomes water vapor and is evaporated into the air. The water vapor of the trouser socks condenses into small water droplets when it encounters cold air at high altitude.

These small droplets are small, with a diameter of only millimeters and a maximum of millimeters. They are small and light, held in the air by updrafts in the air. It was these small droplets of water that gathered together in the air to form clouds.

For these small droplets to fall to the ground as raindrops, they would have to increase in size by more than 1 million times.

Summary. It rains in the sky because the ice crystals in the upper layers of the clouds increase in size and fall between the droplets in the lower part of the clouds, and the droplets get bigger and bigger, and when they are too big for the updrafts to support them, it rains.

It rains in the sky because the ice crystals in the upper layer of the clouds increase in size, and when they fall between the water droplets in the lower part of the clouds, the water droplets will grow larger and larger, and when they are so big that the updrafts can't support them, it will rain.

Rivers, rivers, lakes and seas are exposed to the sun, and the water will turn into vapour. The water vapor rises and turns into small droplets, and finally into clouds. The small water droplets or Xiaoice crystals in the cloud file code are supported by the air flow below, and the rising air flow is constantly transporting water vapor from below to the clouds.

When it rains in the sky, the water from the ground and the ocean evaporates and rises into the air, and after reaching a certain height, these water vapors condense into water to form clouds and grow larger, so large that the air cannot lift them, so they fall into rain.

Rain is a natural sight in which water on Earth is exposed to sunlight and evaporates into the air as water vapor. When water vapour meets cold air at high altitude, it condenses into small water droplets. These small droplets are small, with a diameter of only millimeters and a maximum of millimeters.

They are small and light, held in the air by updrafts in the air. It was these small droplets of water that gathered together in the air to form clouds. For these small droplets to fall to the ground as raindrops, the volume of their body and sail will increase by about 1 million times.

The process of rainfall depends on many factors such as the type of cloud, temperature, humidity, and wind speed, among others. Warm clouds are more likely to rain than cold clouds because there is enough heat present in the warm clouds to facilitate the nucleation process. Clouds with high humidity and low wind speeds are also more prone to rain because these conditions facilitate the process of water evaporation.

Signs before the rain

1. High air humidity.

The humidity of the air becomes very high before the rain, and if you are not careful, it may cause fog to enter your body.

2. Swarms of flying ants.

Before the rain, due to the change in air currents, many flying ants will become restless and form a large flying team to fly in the night sky.

3. Frog calls.

Frogs are sensitive to humidity, and when the humidity rises before and on rainy days, the frogs perceive this change and express their uneasiness by chirping.

4. Thunder and lightning.

Before rain, thunder and lightning generally appear in the sky, and it is usually accompanied by loud flashes of light and loud noises.

5. Wind direction and speed.

Before rain, the wind direction and speed usually change, and the temperature of the wind is usually lower than the surrounding air, and the temperature difference can cause rain.

Summary. It rains in the sky because the water vapor cools and condenses in the air into small water droplets, which gather to form clouds. When clouds are too large to hold air, they fall from the clouds.

When it rains in the sky, the reason for the water vapor is that the air cools and condenses into small water droplets, which gather to form clouds. When clouds are large enough to hold air without pins, they fall from the clouds.

Rain refers to a natural precipitation phenomenon, but in fact, this phenomenon can also be divided into many different types, such as frontal rain, convective rain, terrain rain, typhoon rain, and the frontal rain in Zhuzhou is also called plum rain, and the reasons for the occurrence of some different rains are different.

To put it simply, water evaporates to form water vapor, which is cold, condenses, falls to the ground, and forms rain.

As rivers, rivers, lakes, and seas are irradiated by the sun, the water inside them becomes water vapor. The water vapor rises and turns into small droplets, and finally into clouds. The small water droplets and Xiaoice crystals that make up the cloud are supported by the air flow below, but the rising air flow is still transporting water vapor in.

The small water droplets and Xiaoice crystals in the cloud collide with each other in motion, thus increasing in size. Then, as the volume of the ice crystals in the upper layer of the cloud slowly increases, the water droplets fall between the droplets in the lower part of the cloud, and the water droplets become larger and larger. When these droplets are too big for the updrafts to hold them, it rains.

This is a physical phenomenon and a law of nature.

Rain is a natural phenomenon, so why does it rain?

The sky will rain for the following reasons:1. When rivers, rivers, lakes and seas are irradiated by the sun, the water will turn into water vapor, rise and turn into small droplets, and finally turn into clouds.

2. The small water droplets and Xiaoice crystals that make up the cloud are supported by the air flow below, and the updraft also continuously transports water vapor from below to the cloud.

3. 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 slowly become larger, and as the volume of the ice crystals in the upper layer of the cloud increases, they fall between the water droplets in the lower part of the cloud. The water droplets will get bigger and bigger, and when they are too big for the updrafts to support them, it will rain.
