The North Pacific Subtropical Gyre and the much smaller North Pacific Subpolar Gyre make up the two major gyre systems in the mid-latitudes of the Northern Pacific Ocean. This two-gyre circulation in the North Pacific is driven by the trade and westerly winds. [2]
The North Pacific Current is formed by the collision of the Kuroshio Current, running northward off the coast of Japan, and the Oyashio Current, which is a cold subarctic current that flows south and circulates counterclockwise along the western North Pacific Ocean. In the eastern North Pacific off southern British Columbia, it splits into the ...
The North Pacific Subtropical Gyre (NPSG) is the largest contiguous ecosystem on earth. In oceanography, a subtropical gyre is a ring-like system of ocean currents rotating clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere caused by the Coriolis Effect. They generally form in large open ocean areas that lie ...
The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant. The smaller-scale weather systems – mid-latitude depressions , or tropical convective cells – occur chaotically, and long-range weather predictions of those cannot be made beyond ten days in practice, or a ...
The flow turns north along the western coast of South America in the Humboldt Current, the eastern boundary current that completes the South Pacific Gyre circulation. Like the North Pacific Gyre, the South Pacific Gyre has an elevated concentration of plastic waste near the center, termed the South Pacific garbage patch.
North Atlantic Gyre – Major circular system of ocean currents; North Pacific Gyre – Major circulating system of ocean currents; Ross Gyre – Circulating system of ocean currents in the Ross Sea; South Atlantic Gyre – Subtropical gyre in the south Atlantic Ocean; South Pacific Gyre – Major circulating system of ocean currents
It is a low pressure system that strengthens with height in accordance with the thermal wind relationship. If a weak surface circulation forms in response to such a feature at subtropical latitudes of the eastern north Pacific or north Indian oceans, it is called a subtropical cyclone. Cloud cover and rainfall mainly occurs with these systems ...
The NPGO has global impacts outside of the Eastern North Pacific. Its secondary role in modeling SSTa suggest that tropically coupled dynamics could play a driving role in NPGO fluctuations. [ 4 ] [ 1 ] It is quite possible that with continuing climate change the NPGO can aid in determining underlying drivers of decadal ecosystem variability ...
