More evidence that this event is not going to be the juggernaut that some thought is this article that classified el nino events by their evolution and intensity.
Historical change of El Niño properties sheds light on future changes of extreme El Niño (pnas.org)
"Strong-Basin wide", "Moderate east pacific" and Moderate Central Pacific". Acccording to this piece, the current event is NOT a strong basin wide event, but a rather a dead-ringer for moderate-east based event in that it:
1) Followed a la nina
2) Began biased extremely east and is propagating westward.
In fact, it even specifically infers that classification based soley on location of maximum anomalies would mix strong basin wide and moderate east based events. I think many are mistaking this event for a SBW when in fact, if you examine the evolution, its a moderate east based event. This is also consistent with the MEI and RONI.
