High Level Clouds


Cirrus

Cirrus clouds are delicate, feathery clouds that are made mostly of ice crystals. Their wispy shape comes from wind currents which twist and spread the ice crystals into strands.



Cirrostratus

Cirrostratus clouds are thin, white clouds that cover the whole sky like a veil. These clouds are most commonly seen in the winter, and can cause the appearance of a halo around the sun or the moon.



Cirrocumulus

Cirrocumulus clouds are thin, sometimes patchy, sheet-like clouds. They sometimes look like they’re full of ripples or are made of small grains.
