Oceanic Niño Index (ONI)

Con fines históricos, los períodos que se encuentran por debajo y por encima de la Temperatura Superficial del Mar (TSM) normal son de color azul y rojo respectivamente, cuando el límite alcanza un mínimo de 5 temporadas consecutivas se traslapan. La ONI es una medida de la Niño-Oscilación del Sur, y otros índices pueden confirmar las características consistentes con un fenómeno oceánico-atmosférico que ocurren en estos períodos.
