Soaring
Soaring animals and aircraft may alternate glides with periods of soaring in rising air. Five principal types of lift are used: thermals, ridge lift, lee waves, convergences and dynamic soaring. Dynamic soaring is used predominately by birds, and some model aircraft, though it has also been achieved on rare occasions by piloted aircraft.
Examples of soaring flight by birds are the use of:
- Thermals and convergences by raptors such as vultures
- Ridge lift by gulls near cliffs
- Wave lift by migrating birds
- Dynamic effects near the surface of the sea by albatrosses
For humans, soaring is the basis for three air sports: gliding, hang gliding and paragliding.

Famous quotes containing the word soaring:
“O Holy Wisdom, Soaring Power, encompass us with wings unfurled,
and carry us, encircling all, above, below, and through the world.”

“There are in me, in literary terms, two distinct characters: one who is taken with roaring, with lyricism, with soaring aloft, with all the sonorities of phrase and summits of thought; and the other who digs and scratches for truth all he can, who is as interested in the little facts as the big ones, who would like to make you feel materially the things he reproduces.”
—Gustave Flaubert (1821–1880)
