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:
“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)
“These boys who love their mother
who loves men, who passes on
her sons to other women;
The cloud across the sky. The windy pines.
the trickle gurgle in the swampy meadow
this is our body.”
—Gary Snyder (b. 1930)
“I belong to the fag-end of Victorian liberalism, and can look back to an age whose challenges were moderate in their tone, and the cloud on whose horizon was no bigger than a man’s hand.”
—E.M. (Edward Morgan)
