Cloud Types
For temperate regions, a “low” cloud base below 6500 ft (2000 m) is given what prefix?
NONE
- For temeprate regions, low cloud with a base below 6500 ft (2000 m) above ground level (agl) carries no prefix
- If the cloudbase is over 6500 ft agl, it is classified as “medium” cloud and the cloud name is prefixed with ALTO-
- If the cloudbase is over 16,500 ft (5000m) agl, the clouds are called “high”cloud and given the prefiex CIRRO

- ____ is usually found in the middle level, but it often extends higher
- ____ is almost always found in the middle level, but it can extend into the other two levels
- ____ and ____ usually have their bases in the low level, but their vertical extent isoften so great that their tops may reach into the middle and high levels

Cloud Types
Cirrus clouds contain WATER or ICE CRYSTALS
ICE CRYSTALS
2
Cloud Types
Icing conditions are MODERATE or SEVERE or NON EXISTENT in Cirrus clouds
NON EXISTENT
- clouds contain ice crystals, not liquid water
2
Cloud Types
“Detached clouds of white, delicate, feathery or fibrous apperance or white patches or bands. They appear to move without any significant change in the form or shape”
This is a definition of what cloud type
CIRRUS
(Ci)
2
Cloud Types
“A transparent white viel, not thick enough to obscure the sun or moon. Sunlight passing through it is strong enough that shadows are still visible on the grond. The ice crystals refract the light to produce haloes around the sun or moon”
This is a definition of what cloud type
CIRROSTRATUS
(Cs)
3
Cloud Types
“Regular, thin patches of high cloud, without shadows, with regular ripples or lumps. Most of the elements have an apparent width of less than one degree, the apparent width of a little finger held at arms length”
This is a definition of what cloud type
CIRROCUMULUS
