Flying hair usually occurs in warm seasons, which is different from some common weather phenomena such as sleet, heavy snow and freezing rain in winter.

So many people are curious about how hail is formed. Hail is in the form of very hard ice, and then falls from the sky to the ground in the form of cone hail, spherical hail and irregular hail.

In fact, when the water droplets in the air become bigger and bigger, and the buoyancy of the air can't support these water droplets, precipitation is formed, which is easy to understand, but ice cubes are much heavier than raindrops, so how can these ice cubes stay in the atmosphere for so long?

In fact, the production of ice has a great relationship with the strong updraft, and strong convection activities are most likely to occur in summer, while the water droplets with the temperature below 0 degrees in the cloud do not freeze, and the snowflakes in the cloud will freeze into tiny ice particles after colliding with each other.

These forces begin to slowly decrease in the atmosphere, but after encountering the updraft, the newly generated ice particles will rise with the updraft until they rise above the clouds, which will cause more supercooled water droplets to condense on the ice particles, thus forming hail blocks.

Hail will fall when it is fast or slow, but it will encounter rising airflow. Hail will fluctuate repeatedly in the clouds, just like table tennis rolling in a lottery machine, but the difference is that the hail will fluctuate more and more because of sunny moments.

Eventually, when these updrafts can't set off these heavier and heavier ice cubes, these ice chopsticks will eventually land on the ground in the sky, and the strongest updraft can even make the diameter of hail reach 10 cm.

Hail is very harmful. Although hail is relatively small in scope and short in time, it will bring great losses to communication industry, transportation industry, construction industry, agriculture industry, electric power industry and people's lives and property. According to statistics, the annual economic losses caused by hail in China can reach several billion yuan.
