Shows up OK at http://www.osdpd.noaa.gov/PSB/EPS/SST/climo.html. Look
at the
Equator - not 10S. Admittedly not one of the strongest but looks like
an El
Nino to me.

... well now, I'm thoroughly confused! The TAO display, explicitly set
up to monitor these events, shows nothing 'worse' than +0.5degC or a
little higher in the 100-120degW zone; the map you have pointed to
appears to indicate up to 3degC or even higher anomalies! Even allowing
that the base-climatology may be different, that's a big difference.

"The range of temperatures displayed is -5.0 to +5.0 K. Each color
gradation on the color bar is 0.5 K."

You are confused?

The people writing the legends for these charts think the temperature
can go a lot lower than it has been possible to replicate in a
laboratory.
