Empirical orthogonal function analysis of winter sea surface temperature (SST) anomalies over the Pacific domain (60{degrees}N-20{degrees}S) reveals an El Nino-Southern Oscillation (ENSO) mode that is linked to the eastern North Pacific, and a North Pacific mode that is linearly independent of ENSO. The North Pacific mode exhibits maximum amplitude and variance explained along {approximately} 40{degrees}N, west of {approximately} 170{degrees}W. SSTs in this region have decreased by {approximately} 1.5{degrees}C from 1950 to 1987. The cooling in winter has been associated with a strengthening of the overlying westerly winds. 17 refs., 4 figs.
