In what season does hail usually appear easily?

In summer, when a large amount of water vapor rises to the temperature below -20C, it will become small ice beads. When the rising air can't hold it, small ice beads will fall from the sky. When falling, the rising water vapor will freeze on their surfaces intermittently, and small ice beads will fall to the ground wrapped in ice coats in the air, forming hail.

Hail usually occurs from March to 10, that is, spring, summer and autumn, with summer and the turn of spring and summer being the most common. In a day, it is the most common in the afternoon to the evening, and it mostly happens in the afternoon from 14 to 16. Geographically, hail weather in China is mostly distributed in the central and eastern regions, and less in the western region, but the area with the most hail in China is the Qinghai-Tibet Plateau.

Hail is a weather phenomenon, and it is a phenomenon that water vapor in the atmosphere quickly cools to form large ice cubes and falls to the ground. When hail is formed, there must be a fairly thick unstable layer in the atmosphere. The vertical thickness of the hail cloud should not be less than 6 to 8 kilometers, and the water content is generally 3 to 8 grams per cubic meter. There is an inclined, strong and uneven updraft in the cloud.

Hail causes damage.

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 other weather processes such as strong winds and heavy rains. China is a country with frequent hail disasters. Hail brings huge losses to agriculture, construction, communication, electricity, transportation and people's lives and property every year.
