1. High clouds—composed almost entirely of ice crystals, the bases of these clouds start at 16,500 feet (5,032 meters) and reach 45,000 feet (13,725 meters).
2. Cirrus —thin feather-like crystal clouds in patches or narrow bands. The large ice crystals that often trail downward in well-defined wisps are called mare's tails.
3. Cirrostratusis—a thin, white cloud layer that resembles a veil or sheet. This layer can be striated or fibrous. Because of the ice content, these clouds are associated with the halos that surround the sun or moon.
<span>4. Cirrocumulus—thin clouds that appear as small white flakes or cotton patches and may contain super-cooled water.</span>
