Clouds absorb the heat emitted from the ground and reflect it back to the ground, which helps keep the earth warm. Pen & Fun & Pavilion www.biquge.info but the clouds also reflect the sunlight directly back into space, so that it has a cooling effect. Which effect prevails depends on the shape and position of the cloud.

In this layer of the atmosphere more than ten kilometers from the ground, the closer to the ground, the higher the temperature and the more abundant 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, animals and plants, evaporates into the air at any time and becomes water vapor. When water vapour enters the atmosphere, it becomes clouds that cause rain, or condense into frost and dew, and then return to the ground, seep into the soil, or flow into rivers, lakes and seas. Later, it evaporates (vaporizes) again, and then condenses (condensation) and declines. The cycle goes on and on.

Water vapor enters the lower atmosphere from the evaporation surface, where the temperature is high, and if this hot and humid air is lifted, the temperature will gradually decrease, and at 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 0C, the excess water vapor liquefies into small droplets; If the temperature is below 0C, 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, what we call clouds are formed.

Cloud, commonly used in Chinese characters, is generally used as a noun to denote a collection of water droplets or gas or ice crystal colloids that remain in the atmosphere; Old Chinese is also used as a verb to speak.
