ice grains

Ice grains are tiny pieces of ice, often just millimeters in size, found in clouds, fog, or snow. They form when water vapor or supercooled droplets freeze into small, solid ice particles. These grains can vary in shape and clarity depending on how they form and grow, and they can collide and stick together to create larger ice structures like snowflakes or hail. Ice grains play an important role in weather processes and can influence cloud properties and precipitation.
