摘要：
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 similar to 40 degrees N, west of similar to 170 degrees W. SSTs in this region have decreased by similar to 1.5 degrees C from 1950 to 1987. The cooling in winter has been associated with a strengthening of the overlying westerly winds.
