Right through to next spring at least. Always interesting to see how global temperatures respond to ENSO changes. UAH has August as 3rd warmest on record and similar temperatures to last year. The world just isn't cooling from the last El Nino, even though we've had a short La Nina since then. These are unprecedented global temperatures in such an ENSO state, in recorded history.

Take a look at the N Atlantic SST anomaly. http://polar.ncep.noaa.gov/sst/rtg_l...maly_oper0.png never seen it so warm.

It was actually a good deal cooler (overall) during the recent El Nino.

I know its tempting to link ENSO with global temperatures, but if I remember correctly, there is a very poor correlation. The bottom line is we do not understand the driver of ENSO. Chicken or egg? Scrambled in this case.
Global warming must be one factor in the behaviour of ENSO. I can't understand why people think ENSO contributes to global warming.

I think it's because during El Nino there's a net transfer of heat from the oceans to the atmosphere. Then, during the next part of the cycle the transfer is effectively reversed. It's really a just a cycle superimposed upon global warming. (Though global warming may affect the cycle of course!)

Two things, Len:

A. 'People' don't think ENSO contributes to GW, however, how global warming will contribute to the frequency and behaviour of ENSO in the future, is not known.

a. There is an excellent correlation between ENSO and global temperatures, with a time lag of around 3-6 months.

If you choose the latest monthly SST anomaly, N Atlantic is not quite so warm.
