Gyre

A gyre in oceanography is any large system of rotating ocean currents, particularly those involved with large wind movements. Gyres are caused by the Coriolis Effect; planetary vorticity along with horizontal and vertical friction, which determine the circulation patterns from the wind curl (torque). The term gyre can be used to refer to any type of vortex in the air or the sea, even one that is man-made, but it is most commonly used in oceanography to refer to the major ocean systems.

Famous quotes containing the word gyre:

“Lovers of horses and of women, shall
From marble of a broken sepulchre
Or dark betwixt the polecat and the owl,
Or any rich, dark nothing disinter
The workman, noble and saint, and all things run
On that fashionable gyre again.”
—William Butler Yeats (1865–1939)

“‘Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mismy were the borogoves,
And the mome raths outgrabe.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

“‘Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.
“Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
