zonal pseudo wind stress as described by the POP model. The data are averaged between
5"N and 5 oS, the vertical axis represents the time, the horizontal axis represents the

coherently with a phase difference of about 90° (as theoretically expected) over
most of the time which in itself is an expression of predictability.
Model studies also indicate the predictability of ENSO. Such numerical experiments were conducted in the mid-eighties at the Geophysical Fluid Dynamics Laboratory (GFDL) to simulate interannual variability. Observed SST's for the period
1962-1976 were specified as lower boundary condition for an atmospheric general
