Hail is a form of precipitation composed of rime or glaze ice pellets that fall to the ground, typically originating from severe thunderstorms. Its formation requires a combination of strong atmospheric updrafts within a cumulonimbus cloud and stratifications of temperature, allowing supercooled water droplets to be lifted to high altitudes where temperatures are significantly below freezing. The hailstone grows by accreting layers of ice and frozen water droplets as it rises and falls within the turbulent cloud structure. The resulting particles exhibit a wide range of sizes, from small pebbles to large destructive masses, and their impact is determined by their mass and the kinetic energy acquired during their descent.
