In what season is hail more common?
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 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 also a disastrous natural weather, which can be divided into light hail, medium hail and heavy hail according to hail diameter, cumulative hail time and cumulative hail thickness. Hail disaster occurs in a small range and lasts for a short time, but it is swift and violent, with generally high intensity, often accompanied by other weather such as rainstorm and storm, which poses a great threat to agriculture, construction, communication, electricity and people's lives and property.
