irregular crystal

In meteorology, precipitation forms from atmospheric moisture that condenses into clouds. These clouds contain particles that grow and aggregate, eventually falling to Earth as drizzle, rain, snow, ice crystals, or hail. Snow crystals, which are aggregates of ice crystals, typically have a hexagonal pattern and can form in intricate shapes depending on temperature and available water vapor.1

Irregular crystals, in the context of meteorology, refer to snow crystals that do not conform to the more common hexagonal or dendritic shapes. Their formation is influenced by the specific atmospheric conditions, including temperature and humidity, during their growth within clouds. These irregular forms are a natural variation in the crystallization process of atmospheric ice.12
