- Cirrus - "mares' tails" clouds - wispy, feathery, with delicate fibres, streakes, or plumes.
- Cirrostratus - clouds like veils, formed from fused sheets of ice crystals, having a milky look, with Sun and Moon halos.
- Cirrocumulus - dappled clouds in small white flakes or tufts; occur in lines or groups, sometimes in ripples, forming a "mackerel" sky.
- Cumulus - sharply outlined, puffy, billowy, flat-based clouds with swelling tops; associated with fair weather.
- Cumulonimbus - dense, heavy, massive clouds associated with dark thunderstorms, hard showers, and great vertical development, with towering, cirrus-topped plume blown into anvil-shaped head.
