Snoform, or snow formation, occurs when water vapor in the atmosphere freezes into ice crystals, typically in clouds. These ice crystals grow and aggregate as they collide with supercooled water droplets or other ice crystals, eventually becoming heavy enough to fall to the ground as snowflakes. The specific shape of snowflakes is influenced by temperature and humidity conditions during their formation. Factors such as atmospheric pressure and wind can also affect how snow is deposited on the surface.
