30 paź 2023 · Overview. Large, circular-moving loops of water driven by major wind belts. 5 subtropical gyres: North Atlantic, South Atlantic, North Pacific, South Pacific, Indian Ocean. Gyre centers at ~30 degrees north or south latitude. Subtropical gyres rotate clockwise. Western Boundary Currents. Narrow and deep. Steep, narrow slope to sea surface.
Part 1: Ocean Gyres Major Ocean Currents and Their Gyres. Gulf Stream: Part of the North Atlantic Gyre; a warm water current that flows from the Gulf of Mexico along the eastern coast of the United States. Humboldt Current: Part of the South Pacific Gyre; a cold water current that flows northward along the western coast of South America.

27 lis 2023 · An ocean gyre is a large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation. The movement of the world’s major ocean gyres helps drive the “ ocean conveyor belt.” The ocean conveyor belt circulates ocean water around the entire planet.
The global pattern of winds together with the Coriolis Effect and Ekman Transport produce large-scale currents in the world ocean. Ocean surface currents organize into Gyres that are characterized by circulation at the scale of the ocean basin. The figure below shows the basic pattern.
10 cze 2024 · There are five major gyres in the oceans; the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian (Figure \(\PageIndex{2}\)). The North Pacific gyre is composed of the North Equatorial Current on its southern boundary, which turns into the Kuroshio Current (a.k.a. the Japan Current) bringing warm water north towards Japan.
