Il MEI che è l'indice più completo delle SSTA Pacifiche, non ha avuto il picco in gennaio ma in novembre e dicembre. A meno di sorprese nei prossimi mesi, peraltro escluse dai principali centri di ricerca, l'intensità è stata e sarà inferiore a quella dell'episodio di Nino moderato del 2006-07.
Questo raffreddamento è in realtà molto lontano da quelli del 55-56, del 70-71, del 73-74, del 75-76, ma anche da quello del 88-89. E' invece simile come intensità a quello molto recente del 98-99 che si prolungò, con la stessa magnitudine, anche alla stagione successiva.
