Pacific Ocean

Pacific Ocean North Equatorial Current A warm current, it flows westwiirds in the north of the equator. This current is produced by the north-east trades.
South Equatorial Current A warm. current, it flows westwards in the south of the equator. This current is produced by the south-east trades.

Kuro Siwo Current The north-east trade winds blow the north equatorial current off the coasts of the Philippine~ and Formosa into the East China Sea as the Kuro Siwo 01 Kuroshio or Japan current. It is a warm current.

North Pacific Current From the south-east coast oj Japan, the current flows right across the ocean from wes1 to east as the North Pacific current. North Pacific curren1 is a warm current.

Alaska Current A cold current, Alaska current flows anti-clockwise along the coast of British Columbia and Alaska. This current is a branch of the North Pacific current.
Californian Current A cold current, the Californian current flows southwards along the Pacific coastline of the USA. This current is caused by the upwelling of colder water from greater depths due to the southward deflection of the North Pacific Current. The Californian current eventually joins the North Equatorial Current, thus com­pleting the cycle.

Peru or Humboldt Current Reaching the south western coast of South America, the South Pacific Current turns northward as Peru current. It is a cold current.
Counter Equatorial Current Between the North and the South Equatorial Currents, a current flows from west to east which is known as the Counter Equatorial Current, a warm current.

Oya Siwo or Oyashio Current The Cold Alaskan current or Bering current creeps southwards from the narrow Bering strait and is joined by the Okhotsk current (a cold current) to meet the warm Japan current as the Oya Siwo or Oyashio (a cold current).
