Formed like a cirrus or tendril; -- said of appendages of both animals and plants.
A cloud type formed of ice crystals at high altitudes (greater than 6 km above sea level) which looks wispy or like a paintbrush stroked across the sky.
description of high atmospheric clouds composed of small particles, mainly ice crystals, that appear thin, slightly transparent and white in color. Cirrocumuls, cirrostratus, and cirrus are all types of cirriform clouds.
Clouds composed of small particles, mostly ice crystals. Because the particles are fairly widely dispersed, this usually results in relative transparency and whiteness, often producing a halo phenomena not observed in other clouds forms. These clouds generally have bases above 20,000 feet in the mid-latitudes, and are classified as high clouds. They include all varieties of cirrus, cirrocumulus, and cirrostratus clouds.
