How are clouds and rain formed? What is the relationship between the two? Clouds made up of liquid water droplets, including supercooled water droplets, are called hydrogenic clouds.

If there are conditions for the cloud droplets to increase into raindrops and make the raindrops have a certain rate of decline, then it is rain or drizzle that falls. Clouds made up of ice crystals are called cryogenic clouds, while clouds that are made up of water droplets (mainly supercooled water droplets) and ice crystals together are called hybrid clouds. Ice crystals or snowflakes that fall from ice-forming clouds or mixed clouds fall into the air layer above 0, and after melting, they also become raindrops that fall to the ground, forming rainfall.

With a large amount of water vapor and air cooling, the water vapor cannot condense to form clouds, and another condition for water vapor to condense is needed. Clouds are in the air, most of them are composed of water vapor and dust particles in the air, and rain is a further change of clouds, which is the clouds in the air when they encounter cold air and condense into water droplets, and then fall to the ground. If the air is absolutely pure and free of any impurities, the water vapor molecules cannot attach.

The ability of individual water vapor molecules to merge with each other is very small under normal temperature conditions, and they often separate when they collide.

It is because clouds are formed in the sky, and then the clouds cause rain, and it is also because of the change in air pressure. The necessary relationship between the two is also a causal relationship, or a relationship of mutual dependence, because only when clouds are formed can rain be formed.

Clouds are actually water vapor in the sky, and when the water vapor gathers to a certain extent, it will form small water droplets, forming rainfall, and there are many types of rain, such as showers, convective rain, etc.

There is a lot of water vapor and dust in the air, and these things rise into the air to form clouds. When clouds meet air in the air, they condense into water droplets, which form rain. It is because of clouds that rain is formed, and the two are cause and effect.

First of all, clouds are formed by the combination of water vapor and pure particles in the air, then rain is caused by clouds encountering some cold air in the air, and finally it becomes rain when the pressure is relatively high, which is directly related.

It is formed by the addition of water vapor in the air to the wind. There is nothing to do with each other.

The relationship between clouds and rain: When rain or snow falls to the ground, it flows into rivers or glaciers, or seeps into the ground to become groundwater. Eventually, the water flows into the sea, where the water evaporates again and rises into clouds, which in turn form rain and fall to the ground.

The various links of the water cycle are interconnected, and water appears in the form of liquids, solids, gases, etc. Water evaporates not only on the surface of the sea, but also on land. Eventually, the water vapor condenses and descends to land and sea in the form of rain, snow, dew, fog, hail, etc.

Almost half of the rain that falls on land quickly evaporates, leaving the other half back into the ocean. Water is like that, it is recycled year after year.

Cloud formation is mainly caused by condensation of water vapor.

In this layer of the atmosphere more than ten kilometers from the ground, the closer to the ground, the higher the temperature and the denser the air; The higher you go, the cooler the temperature and the thinner the air.

On the other hand, the water surface of rivers, lakes and seas, as well as the water of soil, faucia and plants, evaporate into the air at any time and become water vapor. When water vapour enters the atmosphere, it becomes clouds that cause rain, or condenses into frost and dew, and then returns to the ground, seeping into the soil or flowing into rivers, lakes and seas. Later, it evaporates (vaporizes) again, and then condenses (condensation) and declines.

Cycle after cycle, the cycle is not sensitive.

After the water vapor enters the lower atmosphere from the evaporation surface, the temperature here is high, and the water vapor contained is more, and if the hot and humid air is lifted by the bridge Mingsen, the temperature will gradually decrease, and when it reaches a certain height, the water vapor in the air will reach saturation. If the air continues to be lifted, excess water vapor will be precipitated. If the temperature there is higher than 0°C, the excess water vapor condenses into small droplets; If the temperature is below 0 °C, the excess water vapor condenses into Xiaoice crystals.

When these small water droplets and Xiaoice crystals gradually increase to the point where the human eye can recognize them, they are clouds.

When water droplets in the clouds fall to the ground, it rains.

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.

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.

1. Cloud: Cloud is a visible polymer floating in the air composed of small water droplets or Xiaoice crystals formed by the liquefaction of water vapor in the atmosphere when cold. Clouds are the tangible result of the vast water cycle on Earth.

When the sun shines on the Earth's surface, the water evaporates to form water vapor, and once the water vapor is supersaturated, water molecules collect around the dust (condensation nuclei) in the air, and the resulting water droplets or ice crystals scatter sunlight in all directions, which gives the appearance of clouds. In addition, clouds can take on a variety of shapes, and they are divided into many types depending on the height and shape of the sky.

2. Rain: The water droplets that fall from the clouds, the water on the surface of the land and the sea 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, which collide with each other in the clouds and merge into large water droplets, and when it is so big that the air can't hold it, it falls from the clouds and forms rain. Rain is the most important source of fresh water in human life, and plants must also be nourished by rain and dew to thrive.

But flooding caused by heavy rains can also bring great disasters to human beings.

3. Snow: In mixed clouds, due to the coexistence of ice and water, the ice crystals continue to condense and increase, becoming snowflakes. When the temperature under the clouds drops below 0, snowflakes can fall all the way to the ground and form snowfall.

Are cumulonimbus clouds formed by rain or clouds?

First, let's talk about how clouds are formed.

Water on the surface. Evaporation turns into water vapor and rises to the sky. When it condenses into clouds, it encounters a cold snap in the sky or something. Saturation is reduced. If it can't float any longer, it will become rain and fall to the earth, and so on.

Clouds are like fog.

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.
