About this map
The major currents as warm or cold flows, each marked at a representative mid-current point. The fact explains what drives it and what it changes: climate, fisheries, or monsoon drift.
This map is conceptual: currents are flows, not points. Learn the gyre logic (clockwise in the north, anticlockwise in the south) and the rule breaks (Somali current reverses with the monsoon).
Exam angles: warm versus cold classification, currents behind famous fisheries (Peru, Benguela, Oyashio), and El Nino/La Nina as Pacific current anomalies.
