Page "El Niño–Southern Oscillation" Paragraph 48

The traditional Niño, also called Eastern Pacific ( EP ) El Niño, involves temperature anomalies in the Eastern Pacific.

However, in the last two decades non-traditional El Niños were observed, in which the usual place of the temperature anomaly ( Nino 1 and 2 ) is not affected, but an anomaly arises in the central Pacific ( Nino 3. 4 ).

The phenomenon is called Central Pacific ( CP ) El Niño, " dateline " El Niño ( because the anomaly arises near the dateline ), or El Niño " Modoki " ( Modoki is Japanese for " similar, but different ").
