Genus cirrus List of cloud types

cirrus uncinus clouds (v-2)



cirrus spissatus (v-3) clouds



cirrus fibratus radiatus (v-8)

abbreviation: ci

cirriform clouds tend wispy , transparent or translucent. isolated cirrus not bring rain; however, large amounts of cirrus can indicate approaching storm system followed fair weather.

there several variations of clouds of cirrus genus based on species , varieties:

species

cirrus fibratus (v-1)

high clouds having traditional mare s tail appearance. these clouds long, fibrous, , curved, no tufts or curls @ ends.
cirrus uncinus (v-2)

filaments up-turned hooks or curls.
cirrus spissatus (v-3)

dense , opaque or opaque patches.
cirrus castellanus (v-4)

a series of dense lumps, or towers , connected thinner base.
cirrus floccus (v-5)

elements take on rounded appearance on top, lower part appearing ragged.




opacity-based varieties

none; translucent except species spissatus inherently opaque.








fibratus pattern-based varieties

cirrus fibratus intortus (v-6)

irregularly curved or tangled filamegnts.
cirrus fibratus vertebratus (v-7)

elements arranged in manner of vertebrate or fish skeleton.








pattern-based variety radiatus

large horizontal bands appear converge @ horizon; associated fibratus , uncinus species.

cirrus fibratus radiatus (v-8)
cirrus uncinus radiatus (v-9)








pattern-based variety duplicatus

sheets @ different layers of upper troposphere, may connected @ 1 or more points; associated fibratus , uncinus species.

cirrus fibratus duplicatus (v-10)
cirrus uncinus duplicatus (v-11)










varieties not commonly associated ci species spissatus, castellanus, or floccus.












precipitation-based supplementary features
