Cloud Formations
Clouds are arranged in three families--low (surface to 6,500 feet), middle (6,500 feet to
16,500 feet), and high (16,500 feet to 45,000 feet)--and are categorized into 10 basic
types that have many different forms and varieties. Two additional types of cloud
formations are cumulonimbus mammatus and lenticularis.
