Cirrus clouds before sunset over trees. Cirrus is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus, meaning "ringlet" or "curling lock of hair". Such a cloud can form at any altitude between 5,000 and 13,700 m (16,500 and 45,000 ft) above sea level. The strands of cloud sometimes appear in tufts of a distinctive form referred to by the common name of "mares' tails". Weiz, Styria, Austria, Central Europe, November 2021
