Summary of High Cloud Genera
There are three main genera in the family of high clouds: cirrus, cirrocumulus, and cirrostratus. Cirrostratus clouds commonly produce halos because they are composed almost entirely of ice crystals. Cirrocumulus and cirrostratus are sometimes informally referred to as "cirriform clouds" because of their frequent association with cirrus. They are given the prefix "cirro-", but this refers more to their altitude range than their physical structure. Cirrocumulus in its pure form is actually a high cumuliform genus, and cirrostratus is stratiform, like altostratus and lower based sheet clouds.

Famous quotes containing the words summary, high, cloud and/or genera:
“Product of a myriad various minds and contending tongues, compact of obscure and minute association, a language has its own abundant and often recondite laws, in the habitual and summary recognition of which scholarship consists.”
—Walter Pater (1839–1894)
“This is of the loon—I do not mean its laugh, but its looning,—is a long-drawn call, as it were, sometimes singularly human to my ear,—hoo-hoo-ooooo, like the hallooing of a man on a very high key, having thrown his voice into his head. I have heard a sound exactly like it when breathing heavily through my own nostrils, half awake at ten at night, suggesting my affinity to the loon; as if its language were but a dialect of my own, after all.”
—Henry David Thoreau (1817–1862)
“On a cloud I saw a child,
And he laughing said to me,
“Pipe a song about a Lamb”;
So I piped with merry chear.
“Piper pipe that song again”—
So I piped, he wept to hear.
“Drop thy pipe thy happy pipe
Sing thy songs of happy chear”;
So I sung the same again
While he wept with joy to hear.”
—William Blake (1757–1827)
“Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity. Nature is a mutable cloud which is always and never the same.”
—Ralph Waldo Emerson (1803–1882)
