How Hail Forms: Science of Hailstone Development in Thunderstorms #127947 (License: Personal Use)

Hail forms when strong updrafts carry water droplets above the freezing line in a cumulonimbus cloud, where they freeze into ice pellets. These pellets then fall, collect supercooled water, and are lifted again-repeating the cycle to grow larger-until gravity overcomes the updraft and they fall as hail. The red arrow marks the warm updraft, blue the freezing line, and the curved path traces a hailstone’s journey.

Used in meteorology education, weather safety guides, and K-12 science curricula to explain severe weather phenomena; matches user intent for understanding storm mechanics or preparing for hail-related hazards.
