CIN or CIN/S- Convective Inhibition. A cap which prevents convection from occurring. A CIN of 50 or below is weak while 200 and above is very strong.
CIRRUS: A principal cloud type present at high altitudes above 18,000 feet and composed of ice crystals.
CIRROCUMULUS: A principal cloud type featuring cirrus clouds with vertical development.
Cirrus Clouds - Thin, wispy clouds that form high in the atmosphere as their water vapor freezes into ice crystals. Cirrus clouds are a principle cloud type.
Clear Sky - When the sky has no clouds.
Cirrus: a cloud of a class characterized by thin white filaments or narrow bands and a composition of ice crystals. These clouds are of high altitude (20,000-40,000 ft or 6000 -12,000 m).
CIRRUS - This, wispy clouds which usually develop above 30,000 feet.
CLEARANCE - A communication from Air Traffic Control authorizing a pilot to enter an area of controlled airspace.
Cirrus - Wispy white feathers high up in the air.
Cumulonimbus - Cumulus + Nimbus (giving precipitation). Very high piles of cloud, dark and mysterious and lead to thunderstorms.
CIRRUS - High level clouds composed mainly of ice crystals. There are many cirrus type clouds such as CIRROSTRATUS and CIRROCUMULUS. The word "cirrus" comes from the Greek word meaning wispy.

They include all varieties of cirrus, cirrocumulus, and cirrostratus clouds. CIRROCUMULUS A cirriform cloud with vertical development, appearing as a thin sheet of small white puffs which give it a rippled effect.
in cirrus formations), they may indicate severe or extreme turbulence.
Some clouds at this level are cirrus, cirrocumulus, and cirrostratusHigh Energy EventIn solar-terrestrial terms, flares (class two or more) with outstanding Centimetric Bursts and SID.
cirrusWispy-looking cloud belonging to a class characterized by thin white filaments or narrow bands and a composition of ice crystals. These clouds are of high altitude (20,000-40,000 feet or 6000-12,000 meters).
Mare's TrailThe name given to thin, wispy cirrus clouds composed of ice crystals that appear as veil patches or strands, often resembling a horse's tail.
High clouds form above 20,000 feet in the cold region of the troposphere, and are denoted by the prefix CIRRO or CIRRUS. At this altitude water almost always freezes so clouds are composed of ice crystals.
"Abraham's tree" is the name given to a cloud form which consists of feather and plume like appendages of cirrus emanating from a point on the distant horizon.
A sundog is a relatively common atmospheric optical phenomenon associated with the reflection/refraction of sunlight by the numerous small ice crystals that make up cirrus or cirrostratus clouds.
Clouds can be categorized into two general groups: cumulus clouds (tall, cotton ball) and stratus clouds (layered); these can be divided even further to 4 sub-groups describing altitude: 20,000 ft and above are the cirrus or cirro clouds ...
dense cirrus from CB clusters, fresh snow, nimbostratus etc., are displayed as white, and low reflectance objects, e.g. much of the earth's surface, is dark grey or black.
A convergence occurs at about 200 mb that produces cirrus that is sucked into the centre of the vortex, making the relatively clear eye of 10-80 km radius, averaging about 35 km.
Halos: Rings or arcs that encircle the sun or moon. These are caused by refraction of light through ice crystals that make up cirrus clouds.
Halos- rings or arcs that seem to encircle the sun or moon and are the result of the refraction of light through the ice ctystals that make up cirrus clouds.
