fallstreak hole -altocumulus stratiformis translucidus lacunosus (v-44)

abbreviation: ac

mid-level stratocumuliform clouds of genus altocumulus not associated weather front can still bring precipitation, in form of virga not reach ground. layered forms of altocumulus indicator of limited convective instability, , therefore stratocumuliform in structure.

mid-level stratocumuliform species

altocumulus stratiformis (always dividable opacity-based varieties)

sheets or relatively flat patches of altocumulus.
altocumulus lenticularis (v-26)

lens-shaped middle cloud. includes informal variant altocumulus kelvin–helmholtz cloud, lenticular spiral indicative of severe turbulence.
altocumulus volutus (v27) elongated, tube shaped, horizontal stratocumuliform cloud.
altocumulus castellanus (v-28)

turreted layer cloud.
altocumulus floccus (v29)

tufted cumuliform clouds ragged bases.




stratocumuliform opacity-based varieties

altocumulus stratiformis translucidus (v-30)

translucent altocumulus through sun or moon can seen.
altocumulus stratiformis perlucidus (v-31)

opaque middle clouds translucent breaks.
altocumulus stratiformis opacus (v-32)

opaque altocumulus obscures sun or moon.








stratocumuliform pattern-based variety radiatus

rows of altocumulus appear converge @ horizon; associated stratiformis species.

altocumulus stratiformis translucidus radiatus (v-33)
altocumulus stratiformis perlucidus radiatus (v-34)
altocumulus stratiformis opacus radiatus (v-35)
