One of the things I like about your blog is that every now and then you point to sources of data that I didn't know existed. A while ago you pointed to the records of the Nino3.4 index. Ever since I've been tracking how the present El Nino is doing relative to the one in 1997-98. In case you haven't noticed, as of Nov. 4 (released just today), the present anomaly 2.8 C is now tied with 1997-98.
The other thing I've noticed is that if you plot the major El Ninos since 1980, they all show a huge run-up in the October/November timeframe. As did the current one. Any movement from here is in the record-breaking category

Thanks Joe.
There are a couple of others indices used to track ENSOs, that I know of.

Most of these -- all, I think -- show this El Nino is still just a little below the 1997-98 El Nino. But as you said, NINO 3.4 does now.
