Based on the FSU(Florida State University)monthly analysis data of wind stress,typical wind stress patterns associated with the El Nino/La Nina are determined with the technique of POP(Principal Oscillation Pattern) analysis.The results show that the oscillations of zonal/meridional wind stresses have the periods of 35,47,57 months/28,38 months,respectively.We also found the coupled relations between zonal/meridional wind stress propagating patterns and ENSO oscillations.It is suggestive that the explanation,simulation and prediction of El Nino/La Nina spatial/temporal evolution should not be based on a single eigenmode but on their interaction,with emphasis on the fact that superimposition and phase locking are important factors for the event cycle.Finally,the authors suggest that the local oscillation is worthy of consideration too.
