We have applied a multiresolution cross-spectral analysis technique to resolve the temporal relationship between the NAO and ENSO. The study shows significant coherence between NAO and Ni¿o3 SST in about 70% of the warm ENSO events from 1900 to 1995, of which 33% and 37% are associated with a 5- to 6-year period (E1) and a 2- to 4-year period (E2) oscillation terms in the spectral decomposition, respectively. The dominant teleconnection pattern associated with changes in the mean atmospheric circulation during the initial winter of a typical E1 and E2 events is the positive phase of the Pacific/North American (PNA) pattern. Non-coherence between the NAO and ENSO occurs during relatively weak Ni¿o3 SST anomaly, with a teleconnection pattern which shows a strong negative phase of the NAO and a pattern which resembles a weak eastward shifted negative phase of the PNA pattern. ¿ 1998 American Geophysical Union
