Cirrus Clouds

Cirrus clouds are a type of high-altitude cloud that generally forms above 20,000 feet (6,000 meters). They are thin and wispy in appearance, often resembling white hair or feathers. Cirrus clouds are composed of ice crystals due to the cold temperatures at the altitudes where they form. These clouds typically indicate fair to pleasant weather, but their appearance can also signal a change in weather, as they often precede the arrival of a warm front or low-pressure system. The term ‘cirrus’ comes from Latin, meaning a ringlet or curling lock of hair.
