How exactly is rain formed? How did it fall from the clouds?

This is because the circulation of the atmosphere is relatively hot, and then when the water vapor reaches the upper levels, it becomes small water droplets when it encounters cold air, and then they form clouds, and when they collide, they become large raindrops, and then they fall.

Rain is formed by water vapor, the water evaporation on the ground floats into the air to gather more and more to form clouds, more and more water in the clouds, the clouds can not bear the weight of water, water falls from the clouds, it forms rain.

Rain is caused by the formation of water droplets caused by the air on the ground that drifts into the air after a certain level of humidity and cools through the clouds. At that time, when the water droplets gathered large enough, they would fall from the clouds due to gravity.

Rain is small droplets of water made up of heat generated by friction in the atmosphere, which then accumulate more and more, and finally become raindrops.

Formation of clouds and rain: The sun shines on the surface of the earth, and the water evaporates to form water vapor, and once the water vapor is supersaturated, water molecules.

It collects around the dust in the air, and the water droplets or ice crystals produced by the limbs scatter sunlight in all directions, and the cloud droplets grow in size and fall down to cause rain.

Clouds refer to staying in the atmosphere.

The water droplets, or the aggregate of gas or ice crystal colloids, are the tangible result of the vast water cycle on Earth. Clouds can be formed into various shapes, and they are also divided into many types due to the different heights and shapes of the calendar in the sky. Cumulonimbus.

The clouds are thick and huge, and the vertical development is extremely prosperous, and it looks like a towering mountain from a distance.

A cloud is a collection of water droplets or ice crystal colloids that remain in the atmosphere.

Therefore, clouds have no color, and we see white clouds and dark clouds because of the problem of light envy.

If the clouds are thin and the sunlight can pass through, then we will look white.

On the other hand, if the clouds are very thick and the sunlight cannot pass through, then you can't see the light when you leak it, so what you see is a dark cloud.

Rain is the water droplets that fall from the clouds, and the water on the surface of the land and the ocean evaporates into water vapor, and the water vapor rises to a certain height and becomes small water droplets when it is cold, and these small water droplets form clouds, and they collide with each other in the clouds and merge into large water droplets, and when it is so big that the air cannot hold it, it falls from the clouds and forms rain.

Rain is produced by atmospheric circulatory disturbances. The specific formation process is as follows:

1. Water on the surface of land and sea evaporates into water vapor.

2. After the water vapor rises to a certain height, it turns into small water droplets when it is cold.

3. These small droplets form the cloud, and they collide with each other in the cloud and merge into large droplets.

4. When it is so big that the air can't hold it, it falls from the clouds and forms rain.

Water on Earth is irradiated by 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 the largest is only 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.

1. When rivers, rivers, lakes and seas are irradiated by the sun, water will turn into water vapor.

2. Water vapor rises and turns into small droplets, and finally becomes clouds. The small water droplets and Xiaoice crystals that make up the cloud collide with each other in motion, and the volume will increase.

3. The water droplets in the lower layer of the cloud slowly become larger, and the ice crystals in the upper layer of the lead cloud will become larger and larger after the volume increases, and they fall between the water droplets in the lower part of the cloud layer.

4. When these water droplets are so big that the good flow of the rising gas socks can't support them, it will rain.

Are cumulonimbus clouds formed by rain or clouds?

Rain is the water droplets that fall from the clouds, the water on the surface of the land and the sea evaporates into water vapor, the water vapor rises to a certain height and then becomes small water droplets when it is cold, these small water droplets form clouds, they collide with each other in the clouds, merge into large water droplets, and when it is too big for the air to support, it falls from the clouds and forms rain.

Saturation is reached when the water vapor contained by the air reaches its maximum capacity. And the higher the temperature, the more water vapor can be contained in the air. When enough water molecules bind to tiny dust particles in the air, and the water molecules themselves bond to each other, they become small water droplets or ice crystals.

If the ground heat is lost, the temperature drops, and the air is quite humid, then when it cools to a certain extent, a part of the water vapor in the air will condense and become many small water droplets, suspended in the air layer near the ground, and fog will be formed. Both it and clouds are caused by a drop in temperature, and fog can actually also be said to be clouds close to the ground.

The water on the ground absorbs heat and turns into water vapor, which rises to the upper layer of the sky vapor. Due to the low temperature of the upper layer of the vapor layer, the volume of water vapor decreases, the specific gravity increases, and the steam decreases.

Water vapor enters the lower atmosphere from the evaporation surface, where the temperature is high, and the water vapor contained is more, due to the high temperature below the vapor layer, it absorbs heat in the process of descending, rises again and cools again, and then falls, so that the volume of the gas gradually decreases, and finally concentrates on the bottom layer of the vapor layer.

If the temperature there is higher than 0, the excess water vapor liquefies into small droplets; If the temperature is below 0, the excess water vapor condenses into Xiaoice crystals. In the bottom layer of the formation of low temperature zone, water vapor concentration to the low temperature zone, these small water droplets and Xiaoice crystals gradually increase to the extent that the human eye can recognize, what we call clouds are formed.

Snow: Solid water in the form of snowflakes that fall to the ground from mixed clouds. Precipitation consisting of large amounts of white, opaque ice crystals (snow crystals) and their polymers (snow masses). Snow is the natural phenomenon of water condensing in the air and then falling, or falling snow; Snow is a form of water in a solid state.

Rain: Water droplets that fall from clouds, water on the surface of land and sea evaporates into water vapor, water vapor rises to a certain height and becomes small water droplets when it is cold, these small water droplets make up clouds, they collide with each other in the clouds, merge into large water droplets, and when it is too big for the air to support, it falls from the clouds and forms rain.

1. The formation of clouds.

When the air with a lot of water vapor rises into the air, the water vapor temperature decreases and liquefifies into small water droplets or condenses into Xiaoice crystals, and these small particles can be lifted by the air updraft to form floating clouds, so the clouds are composed of a large number of water vapor and Xiaoice crystals.

2. The formation of rain.

Under certain conditions, the small water droplets and Xiaoice crystals in the cloud become larger and larger, and when they reach a certain level, the updraft cannot support them, and they will fall, and in the process of falling, the Xiaoice crystals melt into water droplets and fall to the ground together with the original small water droplets, forming rain.

3. The formation of snow.

In winter, sometimes the updraft is weak, and the water vapor in the clouds is cooled and condenses directly on the Xiaoice crystals to form snowflakes, which fall to the ground surface to form snow.

The wet hot air on the ground drifts to the sky with the updraft, due to the lower temperature

Falling condensation into water droplets, zhi into rain falling to the ground; If the temperature difference increases, the DAO condenses into ice particles and becomes hail; When in between, snowflakes are formed. The key is to look at the convection of the upper and lower air, as well as the associated temperature difference!!

Clouds are formed by the condensation of water vapor in the air, and when they condense to a certain extent, they will form small water droplets, forming rain; When condensed, it coalesces into Xiaoice crystals and forms snow.

Are cumulonimbus clouds formed by rain or clouds?

Let's start with the composition of the cloud.

Clouds are composed of a large number of small water droplets or Xiaoice crystals floating in the air that are invisible to the naked eye, or a mixture of small water droplets and Xiaoice crystals. They are very small, most of them are less than one hundredth of a millimeter in diameter, and in a space of 1 cubic meter, tens or even hundreds of millions of them can exist densely. They hang high in the air and do not fall because there is an updraft in the air underneath, and the water droplets or ice crystals in the clouds are small and lightweight, and they descend very slowly.

It takes six hours for a 20-micron diameter cloud droplet to fall from an altitude of 1,000 meters. What's more, the cloud droplets have to break through two hurdles in the process of descending: one is to rush through the top of the updraft, and the other is to withstand the danger of being evaporated again.

It is only when the water vapour continues to condense or bloom on the cloud droplets, and when the cloud droplets collide with each other, and the large water droplets continue to "eat" the small droplets, so that they become larger and larger enough to overcome the resistance of the updraft, and then they can fall to the ground in rain, snow, or other forms.

From clouds to rain, it is actually a process of growth and growth of water droplets or ice crystals.

When a cloud droplet becomes larger, it falls from the cloud, whether it is rain, snow or some other form depends mainly on the temperature in and under the cloud. When the temperature inside the cloud is above zero degrees Celsius, the cloud is composed entirely of water droplets, and when the cloud droplets grow in size and fall, it is rain. Although the temperature inside the cloud is below zero degrees Celsius, if the temperature of the air layer under the cloud is still above zero degrees Celsius, the cloud droplets may be supercooled water droplets, ice crystals or snowflakes that fall when they increase and fall, but they will also melt into raindrops after passing through the warmer air layer under the clouds.

If it doesn't melt completely, it will rain and snow at the same time, and we call this phenomenon sleet. Only when the temperature in the air layer inside and below the clouds is below zero degrees Celsius does it fall snowflakes.

In the hot summer months, sometimes dark clouds roll in and strong winds blow, but no raindrops fall. In winter, sometimes there are only a few thin puffy clouds in the sky, but large snowflakes can fall. This is because the temperature is high in summer, and although there is a strong convective movement, due to the strong evaporation, the water droplets are evaporated before they have time to collide and merge during the descent process.

Winter is different, as the ice crystals not only evaporate less during the landing, but also continue to increase in condensation to the point where they exceed the lift of the air current.

In recent years, meteorological science has developed rapidly. According to the principle of cloud rain, people carry out artificial rain enhancement operations by aircraft or anti-aircraft artillery in the dry season, and spread dry ice (solid carbon dioxide), silver iodide, liquid nitrogen or other chemical agents into the clouds, causing the temperature in the clouds to drop, causing ice crystals to increase and increase and cause rain, and have been successful in success.

Water, steam, clouds, rain, water.

The liquid is illuminated, evaporates, becomes water vapor and rises, reaching a certain height due to the drop in temperature, it becomes ice crystal particles or small water droplets, condensing into clouds. When the clouds evolve to a point where there is too much liquid in them to bear the weight, they will fall as rain.
