Description & Characteristics. These clouds can indicate the approach of precipitation. Clouds are divided into families of high level, middle level, low level, and vertically developing clouds, and are classified again, in accord with their general shape (e.g., cumuliform or stratoform) High level clouds include cirrus, cirrostratus, and cirrocumulus clouds that occur at altitudes between 16,000 and 45,000 feet. While AltoStratus is located higher in the sky (around 2000-7000 meters) and makes it look thinner than Stratus.

As an adult, Luke wanted to classify clouds, though many others had failed at this. They sometimes produce white or coloured rings, spots or arcs of light around the Sun or Moon, that are known as halo phenomena. Found at the same altitude as their cirrus and cirrocumulus counterparts, these clouds are more widely known for being the culprit of sun and moon halos, as they’re composed of ice crystals. Howard’s cloud-naming scheme was detailed and exact—he based his findings on the shape, colour and height of clouds and detailed them using Latin descriptions. Its presence indicates a large amount of moisture in the upper troposphere. cirrostratus (Cs) clouds are shaped like whitish fibrous veils. Roll clouds.
