What type of ice is formed by small supercooled water drops freezing quickly?

Rime ice is formed when small supercooled water droplets in the air freeze rapidly upon contact with a surface, such as trees, power lines, or other objects. This process typically occurs during cold weather conditions, often in fog or low-visibility situations, where the air is saturated with moisture. As these tiny droplets collide with surfaces that are below freezing, they instantly freeze and create a layered accumulation of ice that appears white and frosty.

Rime ice is distinct from other types of ice, such as clear ice, which forms when water freezes slowly, allowing air bubbles to escape, creating a transparent appearance. Instrument ice refers to ice that can interfere with instrumentation, while mixed ice usually refers to a combination of ice types. Understanding these distinctions clarifies how rime ice specifically results from the rapid freezing of supercooled droplets.
