A wispy cloud is a type of cloud that is thin and wispy in appearance. It is also known as a CIRRUS cloud, which is a high-level cloud composed of ice crystals. These clouds are usually found at altitudes of 20, 000 feet or higher and are often seen in the form of long, white, feathery streaks. They are typically made up of ice crystals that form when the air is very cold and dry. Wispy clouds can be seen in many different shapes and sizes, and they are often associated with fair weather.
