Notes 1) Principle of classification , etymology and meaning of the Latin names are given in: Glossary of weather terms for clouds . 2) Mother- clouds other than those mentioned in the above table, may be observed, though seldom. 3) Genera are sorted in decreasing order of altidudes at which they are usually observed.

3 4) Species, varieties, supplementary features and accessory clouds are listed approximately in descending order of frequency of their occurrence; mother- clouds are listed in the same order as the genera. 5) Bold characters = abbreviations of genera, species, varieties, supplementary features & accessory clouds and mother- clouds . The names and abbreviations of the genera are always written with an initial capital. 6) Colors scale: yellow = high level, orange = middle level, blue = low level. classification of clouds with their base height List of all available pictures on this website Back to weather pictures Monitored by BelStat - Your Site Counts Weather & aviation homepage home | e-mail Weather picture of the month Enter SkyStef 2005.
