High-Level Clouds (5-13 km)
1. Cirrus (Ci): Wispy, detached clouds made of ice crystals. They often appear as delicate feathers or filaments.
2. Cirrocumulus (Cc): Small, white patches arranged in rows or ripples. They resemble miniature cotton balls or scales.
3. Cirrostratus (Cs): Thin, sheet-like clouds that cover the sky. They can produce halos around the sun or moon.
Mid-Level Clouds (2-7 km)
4. Altocumulus (Ac): White or gray patches arranged in layers or rounded masses. They often have a wave-like appearance.
5. Altostratus (As): Gray or bluish sheets that cover the sky. They can be thin enough to allow the sun or moon to shine through, but often cause a milky or hazy appearance.
Low-Level Clouds (0-2 km)
6. Stratocumulus (Sc): Gray or white patches arranged in rounded masses or rolls. They are often associated with fair weather.
7. Stratus (St): Gray, featureless clouds that cover the sky like a blanket. They can produce drizzle or light rain.
8. Nimbostratus (Ns): Dark, gray, rain-producing clouds that cover the sky. They are associated with persistent rain or snow.
Clouds with Vertical Development
9. Cumulus (Cu): Puffy, cotton-like clouds with flat bases and rounded tops. They are often associated with fair weather.
10. Cumulonimbus (Cb): Large, towering clouds that produce thunderstorms. They can extend high into the atmosphere, reaching up to 13 km or more.
These are just the 10 main cloud types. There are many more sub-categories and variations depending on their specific shape, features, and associated weather conditions.
