Cirrus clouds are a type of cloud characterized by thin, wispy strands. The name is from the Latin word cirrus, meaning a ringlet or curling lock of hair. Cirrus clouds form anywhere from 16,500 ft (5.0 km) and 45,000 ft (14 km) above sea level.1
Composed of ice crystals that originate from the freezing of supercooled water droplets and generally occurring in fair weather, cirrus clouds point in the direction of air movement at their elevation.2
