There is hail in Sichuan

Hail is a kind of solid precipitation falling from cumulonimbus clouds. Hail is often called hail. Hail is 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 condense into ice particles. In the process of upward movement, it will absorb small ice particles or water droplets around it and grow up until the updraft cannot bear its weight. When it falls to a higher temperature area, its surface will melt into water and absorb the surrounding small water droplets. At this time, if it is lifted by a strong updraft, its surface will condense into ice and snowball again and again until its weight is greater than the buoyancy of the air, that is, it will fall. If it reaches the ground, it is called hail. If it melts into water, it is the rain we usually see.

Last time there was a heavy hail in Neijiang, Sichuan!
