The three main types of high clouds are cirrus, cirrostratus, and cirrocumulus. Cirrocumulus clouds are layered clouds permeated with small cumuliform lumpiness. They also may line up in streets or rows of clouds across the sky denoting localized areas of ascent cloud axes and descent cloud-free channels. Low-Level CloudsCumulus Cu, Stratocumulus Sc, Stratus St, and Cumulonimbus Cb are low clouds composed of water droplets. Cumulonimbus, with its strong vertical updraft, extends well into the high level of clouds. Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere.
