Which type of ice typically shows a combination of both clear and opaque layers?

The type of ice that typically shows a combination of both clear and opaque layers is classified as mixed ice. This occurs when conditions fluctuate between freezing rain and more rapid accumulation of ice particles, leading to the formation of layers that exhibit both clear and opaque characteristics. The clear layers are often formed from supercooled liquid droplets freezing upon contact with a cold surface, resulting in a smooth, transparent layer. In contrast, the opaque layers usually develop when smaller ice particles or larger drops do not freeze uniformly, causing air bubbles to become trapped in the ice, which impairs its transparency.

Understanding mixed ice is crucial for aviation and meteorology as it can present unique hazards, affecting aircraft performance and operations. Recognizing its characteristics helps controllers and pilots make informed decisions regarding flight safety in icy conditions.
