A little knowledge of the weather

Hail is solid precipitation that falls from strong cumulonimbus clouds to the ground. It is as small as a bean and as big as an egg and a fist. The diameter is generally 5 to 50 mm and the size can reach more than 30 cm. Although the hail weather is short in time and small in scope, it is sudden and often accompanied by lightning and strong winds. More hail will lead to the collapse of houses, the destruction of trees and telephone poles, the destruction of crops and the threat to human and animal safety.
