These SST indices are calculated from the Reynolds SST analysis.
The 1971-00 climatology is used in calculating all of the anomalies.
The last column is an operational test on an El Nino definition based on the following:
(nino3 >= 0.5*stddev3),
where nino3 is the three month running mean of the Nino3 anomaly,
and stddev3 is the standard deviations of the respective Nino
indices (as shown above). * implies preliminary
THE EL NINO DEFINITION IS EXPERIMENTAL.
The following standard deviations are used in determining an El Nino state.
Standard deviations are calculated from the 1961-1990 period (not shown).
