gyre Scientific  

/ jīr /

1. A spiral oceanic surface current driven primarily by the global wind system and constrained by the continents surrounding the three ocean basins (Atlantic, Pacific, and Indian). Each ocean basin has a large gyre in the subtropical region, centered around 30° north and south latitude. Smaller gyres occur at 50° north latitude in the North Atlantic and Pacific Oceans. The direction of a gyre's rotation is determined by the prevailing winds in the region, with the large subtropical gyres rotating clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.

Etymology

Origin of gyre

1560–70; < Latin gȳrus < Greek gŷros ring, circle

Explanation

Use the word gyre when you describe the spiral shape that petals make in the face of a flower. You can use the noun gyre in a variety of ways, but it always means a kind of circle, especially one that coils or spirals. You'll see a gyre when you look straight at certain blossoms — the rings of petals in a rose, for example, form a gyre. Some plants have gyres of leaves making concentric circles. In late Middle English, to gyre was to "spin something around in circles," from the Greek root word gyros, "circle or ring."
