Snow grains are small, granular particles of snow that have a granular or crystalline form. They are typically very tiny, often less than 1 millimeter in diameter, and can be found on the surface of snowpack. Unlike typical snowflakes, snow grains have a more irregular shape and can resemble tiny ice pellets or coarse, granular snow. Snow grains form when the conditions are right, typically under specific temperature and humidity conditions.
