 The traditional La Niña, also called Eastern Pacific (EP) La Niña, involves temperature anomalies in the Eastern Pacific.However, in the last two decades, nontraditional La Niña were observed, in which the usual place of the temperature anomaly (Niño 1 and 2) is not affected, but an anomaly arises in the central Pacific (Niño 3.4).The phenomenon is called Central Pacific (CP) La Niña, "dateline" La Niña (because the anomaly arises near the dateline), or La Niña "Modoki" (Modoki is Japanese for "similar, but different").
