Cloud
In meteorology, a cloud is a visible mass of liquid droplets or frozen crystals made of water or various chemicals suspended in the atmosphere above the surface of a planetary body. These suspended particles are also known as aerosols. Clouds in earth's atmosphere are studied in the cloud physics branch of meteorology. Two processes, possibly acting together, can lead to air becoming saturated; cooling the air or adding water vapor to the air. In general, precipitation will fall to the surface; an exception is virga, which evaporates before reaching the surface.

Famous quotes containing the word cloud:
“Here’s neither bush nor shrub to bear off any weather at all. And another storm brewing, I hear it sing i’ the wind. Yond same black cloud, yond huge one, looks like a foul bombard that would shed his liquor. If it should thunder as it did before, I know not where to hide my head. Yond same cloud cannot choose but fall by pailfuls.”
—William Shakespeare (1564–1616)
“To go where? In that Dark—that—in that God? a
radiance? A Lord in the Void? Like an eye in the black cloud in a
dream? Adonoi at last, with you?”
—Allen Ginsberg (b. 1926)
“That which is given to see
At any moment is the residue, shadowed
In gold or emerging into the clear bluish haze
Of uncertainty. We come back to ourselves
Through the rubbish of cloud and tree-spattered pavement.
These days stand like vapor under the trees.”
—John Ashbery (b. 1927)
