Definition

1. Noun:
   • A small, hard ball of ice that falls from the sky during a hailstorm: A hailstone is a single, solid pellet of ice, typically spherical or irregular in shape, that forms in thunderstorm clouds and falls to the ground as precipitation.

  • We could hear the loud sound of hailstones hitting the windowpane.
  • A single large hailstone can contain many layers of ice.

Advanced Usage and Notes

• Formation: Hailstones form when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere, where they freeze. Layers of ice can accumulate as the stone is repeatedly carried up and down, growing larger.
• Measurement: Hailstones are often measured by their diameter (e.g., pea-sized, marble-sized, golf ball-sized) to describe the severity of a storm.
• "Hailstone" vs. "Hail": "Hail" is the collective, uncountable term for the precipitation (e.g., ). "Hailstone" refers to an individual piece of that precipitation.
