Which high-altitude cloud pattern appears as small, ripple-like clusters?

• A. Cirrocumulus
• B. Altostratus
• C. Stratocumulus
• D. Radiation Fog

Answer: (A)

Small ripple-like clusters at high altitude are cirrocumulus. These clouds sit in the upper troposphere, roughly 20,000 to 40,000 feet up, and appear as tiny white patches arranged in rows that create a rippled, fish-scale or “mackerel sky” look. They’re made of ice crystals and signal moisture at high levels rather than implying surface rain. By comparison, altostratus forms a uniform mid-level gray sheet, stratocumulus consists of low, lumpy rolls, and radiation fog sits at the surface from nighttime cooling. The defining clue here is the delicate, high-altitude, ripple-like patchwork, which points to cirrocumulus.
