Hailstorms – UPSC Prelims

What are Hailstorms?
  •  A hailstorm is an unusual weather phenomenon in which balls of ice, called hail, fall from the sky. The ice balls are nothing more than solid precipitation that forms under certain conditions.
How are Hails formed?
  • Hails are formed by cumulonimbus clouds which are generally large and dark and may cause thunder and lightning.
  • In such clouds, winds can blow up the water droplets to heights where they freeze into ice.
  • The frozen droplets begin to fall but are soon pushed back up by the winds and more droplets freeze onto them, resulting in multiple layers of ice on the hailstones.
  • This fall and rise are repeated several times, till the hailstones become too heavy and fall down.
