Sequence diagram of water vapor cloud hail change

The change sequence picture of water vapor cloud hail is as follows:

Cloud: The temperature is high during the day, and a lot of surface water evaporates, so the air contains a lot of water vapor. At this time, after the water vapor rises to the cold sky, some of it liquefies into small water droplets and some condenses into small ice crystals. Clouds in the sky are made up of a large number of small water droplets and small ice crystals. (Liquefaction and sublimation)

Rain: When the clouds get thicker and thicker, it will start to rain. In the process of falling, with the increase of temperature, the small ice crystals in the cloud will melt into small water droplets and fall to the ground together with the original small water droplets in the cloud. This is rain. (melting)

Fog: If there is a large amount of floating dust in the air, water vapor will liquefy into small water droplets when it is cold, attach to the floating dust and float in the air with the floating dust. This is fog. (liquefaction)

Dew: When the weather is hot, the water vapor in the air meets the leaves and flowers with low temperature before morning, and liquefies into small water droplets and adheres to their surfaces. This is dew. (liquefaction)

Snow: When the water vapor rises to a very cold height, it condenses into hexagonal ice flowers, and the ice flowers gather together to form snowflakes or snow masses, which is snow. (ninghua)

Frost: When the temperature drops below 0 degrees Celsius at night, the water vapor near the ground meets the cold objects on the ground and condenses into solid particles attached to the objects. This is Frost. (ninghua)

Hail: Formed in convective clouds. Water vapor rises with the airflow and condenses into small water droplets after cooling. If the temperature continues to decrease with the increase of height and reaches below zero degrees Celsius, water droplets will solidify into ice particles. In the process of its upward movement, it will absorb small ice particles or water droplets around it and grow up until its weight cannot be borne by the upward airflow.

When it falls to a higher temperature area, its surface will melt into water, and at the same time, it will absorb small water droplets around it. At this time, if it is lifted by a strong updraft, its surface will solidify into ice.

Repeatedly snowballing, the volume is getting bigger and bigger until its gravity is greater than the sum of air lift and air buoyancy, that is, it falls down. If it reaches the ground, it is still a solid ice particle and does not melt into water. This is called hail. (curing)
