     Thus the analysis of longer, high-resolution ice cores from the Canadian north could be quite revealing from the viewpoint of Arctic interdecadal variability.

   • 1999, National Research Council, Improving American River Flood Frequency Analyses, page 92:

     Latif and Barnett's postulated mechanism is that self-sustained oscillations at interdecadal time scales can be set up through the influence of the subtropical ocean gyre on SST anomalies in the North Pacific and a subsequent delayed response of wind stress that spins down the gyre.

     This chapter describes variations in tropical cyclone activity over the western North Pacific on time scales from interdecadal to intraseasonal.

     Therefore, there is a striking interdecadal variation of ENSO signal in the upper heat content anomalies of the tropical Pacific during the past 120 years from 1881–2000.
