Kuroshio Current Alvan Chao

Kuroshio Warm water current 24°C 50-300 cm/s 400 m deep 100 km wide Similar to the Gulf Stream Japan current Black stream

Flow Flows from Taiwan to Japan Splits off the coast of Canada Forms the Alaska and California Currents Western boundary current

Rings Produces both warm and cold rings. Warm rings are generally 150 kilometers in diameter Cold rings drift southwestward into the Western Pacific Ocean. Can move northwest and reabsorbed into the Kuroshio.

Fluctuations Seasonal Strongest from May to August Recedes in late summer and fall Increases from January to February Currents deviate

Importance Climate Biology Fisheries Warming effect on Japan Phytoplankton blooms Fish populations Coral Reefs Fisheries Tuna
