What are the nicknames of hail?

Hail is hard spherical, conical or irregular solid precipitation. Hail clouds consist of water droplets, ice crystals and snowflakes. Hail is also called "hail", commonly known as hail, and in some areas it is called "Lengzi", which is the most common in summer or at the turn of spring and summer. It is some ice particles as small as mung beans and soybeans and as big as chestnuts and eggs.

Hail can only be produced in strong convective cumulonimbus clouds, and there is strong airflow in hail clouds. Usually in the direction of the cloud, a strong updraft enters from the bottom of the cloud and flows out from the top of the cloud. There is also a downward airflow flowing in from the middle behind the cloud and out from the bottom of the cloud. The precipitation area of hail usually appears here. These two organized updrafts are connected with the airflow between the downdraft and the environment, so the airflow structure in the general heavy hail cloud is relatively continuous. The updraft in the cloud is stronger than the general thunderstorm cloud, and the hail cloud is fully transported by the strong updraft, and the hail particles are supported and left in the cloud, so that they grow to a considerable size before landing. Small hailstones grow in convective clouds through several collisions between hailstones and supercooled water droplets, and then fall to the ground when the updraft in the clouds can't support them. Heavy hail is produced in a thunderstorm cloud with strong updraft and rich liquid water.

Rain and snow fall from the clouds, and so does hail. But the clouds that hail are very strong cumulonimbus clouds, and only very strong cumulonimbus clouds can hail. Hail disaster is a serious meteorological disaster caused by strong convective weather system. Although it appears in a small range and in a short time, it is fierce and strong, and is often accompanied by sudden disastrous weather processes such as strong winds, heavy precipitation and sharp cooling. The scope of each hail is very small, ranging from several meters to several kilometers wide and 20 ~ 30 kilometers long. However, in mid-latitude continental areas, there are usually more mountains than plains, and hail often occurs in inland areas than in coastal areas.
