On May 11, heavy hail( 冰雹 )came down to an Australian beach. It turned the beach into a sea of white.
It made for an unusual sight and got us wondering, “what causes hail?”
Hail is a type of water in the atmosphere( 大气 ). A piece of hail is called a hailstone. A hailstone begins as a small water drop or a round snowflake in a cloud. The drop grows by collecting many cloud drops. When it is down by a strong wind inside the cloud, the little drop meets with some very cold water drops. These supercooled ( 过冷的 ) drops are still liquid water, even though the temperature is below freezing. When the little drop and these very cold drops merge( 融化 ), the little drop has now become a hailstone.
The little hailstone is thrown up inside the cloud, still collecting other cold drops. The hailstone gets bigger and bigger until it goes to the top of the cloud. Then, because there is no more wind, it falls back down through the cloud. While it is falling, it can hit the earth at a speed of up to 144 kilometers per hour. So it is very dangerous to people, animals, buildings and many other things on the ground.
In Australia, hail can occur( 发生 )at any time of the year. But large hail often happens during spring and early summer.

___________________________
1 . On May, 11.
2 . A strong wind inside the cloud.
3 . They are liquid water.

5 . Yes, they are. Because they may hit the people and the people will be hurt.
