Precipitation

How does sleet form when snowflakes melt and refreeze in the air? Understand the atmospheric layers that create winter precipitation and ice pellets.

How do snowflakes form from water vapour in the atmosphere? Explore the physics of hexagonal symmetry and the nucleation process in cold clouds.

Learn how does hail form through updrafts and supercooled water droplets in cumulonimbus clouds. Discover how ice layers build inside severe storms.

How does frost form? Learn how water vapour changes to ice through deposition and radiative cooling on clear nights. See why ground frost appears.

Learn how does dew form when surfaces cool overnight. Explore how dew point, humidity, and radiative cooling create morning moisture on clear nights.
