Why Does Hail Happen?
It’s not just raindrops that fall during thunderstorms. Sometimes ice falls too. The ice is called hail, and it can form even during the warmth of summer. High up in a storm cloud, it’s so cold that small pieces of ice can form. The winds within the storm cloud can cause the ice to swirl around. When it bumps into cold water droplets, the water freezes onto the ice, making hail grow larger. Eventually, the hail is so big and heavy that it falls to the ground.
Hail can be the size of peas. Large hail can be the size of a grapefruit and destructive. It’s heavy enough to dent cars and break windshields when it falls.
