This research is aimed at investigating 10-30 day quasi-                periodic phenomena in the extratropical, cold season tropospheric               geopotential heights of the Northern Hemisphere.  The search for                such phenomena is justified on experimental, theoretical and                    observational grounds.  They will be examined using theory as                   guidance.   A variety of statistical techniques will be utilized                in order to assess the significance and quantify the importance                 of such phenomena.  Unlike most other studies of this type the                  non-stationarity of these phenomena will be incorporated directly               into the analyses and significance testing.  Also, the analyses                 will allow for regionality and will be based on a much larger                   sample than most prior studies of this nature.  Rotated complex                 principal components (RCPC's) will be used in this study.  The                  RCPC analysis technique, which is a powerful statistical tool,                  has been introduced to meteorologists only very recently.  This                 and several simpler approaches will yield time series of                        amplitude and phase.  The statistical tests will be performed                   primarily on these time series.  The results of this study should               put into prospective various aspects of the variability of                      tropospheric heights in the 10-30 day range, including                          regularity, duration and relation of the quasi-periodic phenomena               to the quasi-stationary state.                                                          This research is important because it applies rigorous                  statistical analysis to a long-term, high quality set of                        atmospheric circulation observations to seek answers to the                     question of the importance of intraseasonal oscillations on                     climate characteristics.
