Why does it hail? What is the reason?

The cause of hail is the collision of cold and hot air. After two air streams collide, the gas may liquefy and then solidify at any time, and naturally turn into hail after solidification.

Hail often falls in some parts of our country, but it is usually seen in the alternating seasons of spring and summer. Some people think that hail usually falls in winter, but it is not. In some areas of our country, hail is even as big as glutinous rice balls. This kind of hail is scary because it may cause problems to the surrounding buildings and personal property at any time. Some people have their houses smashed and some people have their windows smashed. Some people think that hail in spring and summer is a manifestation of resentment.

Many people think that the principle of hail should be very similar to snow. When the temperature reaches 0 degrees, the water in the air condenses into ice, and only when it is blown by the wind will it hail. In fact, the principle of hail is very different.

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, which brings huge losses to agriculture, construction, communication, electricity, transportation and people's lives and property every year.

Many people have encountered hail in thunderstorm weather. Usually, these hailstones will not exceed the size of softball, and they will fall from the storm clouds. However, sometimes the hail is very heavy. Once 80 pounds of hail fall from the sky, when they fall to the ground, they will break into many small pieces. The most mysterious thing is that the huge hail fell from the sky in Wan Li without clouds. There have been many incidents that confirmed that the wings of airplanes were attacked by hail. Scientists still can't explain why there is such a huge hail.
