C12 - Cloud Classification Flashcards
Name the three types of Cloud Classification and their Heights?
- Low-Level = 0 to 6,500 ft.
- Medium-Level (Alto) = 6,500 to 23,000 ft.
- High-Level (Cirro) = 16,500 to 45,000 ft.
Name three basic types of Cloud?
- Stratiform.
- Cumuliform.
- Cirriform.
Clouds which are fibrous, wispy or hair-like in appearance. What am I?
Cirriform Clouds.
Clouds which are generally flat with a large horizontal extent but very little vertical extent. What am I?
Stratiform Clouds.
Clouds which are tall but little horizontal extent. These clouds generally have a heaped appearance and a cauliflower-like shape. What am I?
Cumuliform Clouds.
Name two types of Nimbo-Clouds?
- Nimbostratus.
- Cumulonimbus.
Name five types of Cloud Species?
- Fractus.
- Castellanus.
- Mammatus.
- Lenticularis.
- Capillatus.
Detached clouds with white, delicate filaments of white and are fibrous or have silky sheen. What type of Cloud am I and my abbreviation (2)?
- Cirrus.
- Ci.
A transparent, whitish Cloud with a veil-like or smooth appearance, totally or partly covering the sky and generally producing a halo phenomenon from the sun or moon. What type of Cloud am I and my abbreviation (2)?
- Cirrostratus.
- Cs.
A thin, white patchy cloud which casts no shadows on the ground. What type of Cloud am I and my abbreviation (2)?
- Cirrocumulus.
- Cc.
A greyish or bluish Cloud sheet or Cloud layer of striated, fibrous and uniform appearance. What type of Cloud am I and my abbreviation (2)?
- Altostratus.
- As.
White and/or grey. It forms sheets, layers or patches of Cloud. It can also casts shadows on the ground and sometimes are partly fibrous or diffuse. What type of Cloud am I and my abbreviation (2)?
- Altocumulus.
- Ac.
Grey cloud layer which is often dark. Its appearance may be somewhat diffuse because of continuous rain or snow falling from it. It is thick enough to throughout to block out the sun. What type of Cloud am I and my abbreviation (2)?
- Nimbostratus.
- Ns.
Generally grey, layered Cloud with a uniform base. What type of Cloud am I and my abbreviation (2)?
- Stratus.
- St.
Grey or whitish sheet, layer or patch type Cloud that almost always has dark parts. What type of Cloud am I and my abbreviation (2)?
- Stratocumulus.
- Sc.
Clouds which are markedly sprouting and are often of great vertical extent, their bulging upper part frequently resembles a cauliflower. What type of Cloud am I and my abbreviation (2)?
- Towering Cumulus.
- TCu.
Detached Cloud which is dense and has sharp outlines. Develops vertically as rising mounds, domes or towers. White at the top and relatively dark nearly flat bottom. The upper part often resembles a small cauliflower. What type of Cloud am I and my abbreviation (2)?
- Cumulus.
- Cu.
A heavy and dense cloud with a considerable vertical extent. Under base is often dark and upper portion is smooth and form an anvil shape. What type of Cloud am I and my abbreviation (2)?
- Cumulonimbus.
- Cb.
Clouds which have a sharply defined lens shape. Mainly apply in Cirrocumulus, Altocumulus and Stratocumulus. What type of Cloud Species am I?
Lenticularis.
Flat bases with sections of rising Cloud protruding upwards from various places along their length. Indicates middle level Atmospheric Instability and this the possibility of Thunderstorms developing. Mainly apply in Cirrus, Cirrocumulus, Altocumulus and Stratocumulus. What type of Cloud Species am I?
Castellanus.
Clouds with a ragged appearance, can often be found beneath a storm in the turbulent mixing of Air. Mainly apply to Stratus and Cumulus. What type of Cloud Species am I?
Fractus.
Clearly fibrous or striated structure from a distinct cirriform parts, a sub-category of Cumulonimbus with a shape much like an anvil. What type of Cloud Species am I?
Capillatus.
Cloud base with very distinctive bumpy protuberances and is often seen beneath super-cell storms. What type of Cloud Species am I?
Mammatus.
Name the abbreviation and description for 0 oktas (2)?
- SKC.
- Sky Clear.
