Brief introduction of hail formation principle

Brief introduction of hail formation principle;

Hail is caused by violent weather changes and alternating cold and hot air currents. Hail belongs to solid precipitation, just like rain and snow. It is a hard spherical, conical or irregular solid that falls to the ground from the rapidly developing cumulonimbus clouds.

Introduction to hail:

When the temperature drops to a certain extent, the water vapor in the air will be supersaturated and it will rain. If the temperature drops sharply, hail will form. Hail, also known as hail, commonly known as hail, is called cold wave in some areas. This is a weather phenomenon. Hail is more common in summer or at the turn of spring and summer. At this time, the air humidity is very high, and it is easy to have a climate with unstable temperature. Hail is some ice particles as small as mung beans and soybeans and as big as chestnuts and eggs.

Hazards of hail:

Every year, all parts of China are hit by different degrees of hail. Especially in the mountainous and hilly areas in the north, the eastern part of the Qinghai-Tibet Plateau and the Yunnan-Guizhou area, the terrain is complex, the weather is changeable and there are many hail, which is very harmful to agriculture. Heavy hail destroyed crops and houses, injured people and killed livestock. Extraordinary hail is bigger than grapefruit, which will kill people, destroy a large area of farmland and trees, and destroy buildings and vehicles. It has powerful lethality. Hail disaster is one of the serious natural disasters in China.
