Wind
Wind is the flow of gases on a large scale. On Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in our solar system occur on Neptune and Saturn.

Famous quotes containing the word wind:
“Only when we break the mirror and climb into our vision,
only when we are the wind together streaming and singing,
only in the dream we become with our bones for spears,
we are real at last
and wake.”
—Marge Piercy (b. 1936)
“Oh, never this whelming east wind swells
But it seems like the sea’s return
To the ancient lands where it left the shells
Before the age of the fern....”
—Robert Frost (1874–1963)
“They are very proper forest houses, the stems of the trees collected together and piled up around a man to keep out wind and rain,—made of living green logs, hanging with moss and lichen, and with the curls and fringes of the yellow birch bark, and dripping with resin, fresh and moist, and redolent of swampy odors, with that sort of vigor and perennialness even about them that toadstools suggest.”
—Henry David Thoreau (1817–1862)
