################Reynolds (OI.v2) SST anomaly data shows all four NINO regions well into La Niña territories.

Bob, I notice that the latest PowerPoint presentation from the Climate Prediction Center (NCEP) indicates on slide 15 that the "Surface westward current anomaly persisted in Jun 2010, comparable with that in 1998." (two standard deviations). "On average, ocean surface zonal current anomaly leads the SSTA by a few months."

Note that the 1998 El Nino was quite a bit greater ('El Nino of the century') than the one just ended.

DB: Sorry it took so long to reply. I got caught up in the GISTEMP land surface ratio discussion.
The initial 1998/99 portion of the multiyear La Niña wasn’t especially strong, considering the magnitude of the El Niño that came before it.

So I’m not too surprised to hear the present La Niña is comparable in strength to that one. Keep in mind that what was unusual about the La Niña that followed the 1997/98 El Niño was its length, lasting almost 3 years, minus the few months in 2000 when NINO 3.4 SST anomalies rose above the threshold.
