Causes of hail formation

Hail is produced when the hot and humid airflow rises strongly. In summer, the weather is hot and the sun is scorching the earth, which is easy to produce a lot of hot and humid air near the ground. Hot and humid air rises rapidly and the temperature drops rapidly, sometimes even as low as -3℃. The water vapor in hot air will condense into water droplets when it meets cold air, and quickly freeze to form small ice beads. Small ice beads roll up and down in the clouds, constantly absorbing the surrounding water droplets to condense into ice, getting heavier and heavier, and finally falling from the sky, which is hail.
