Figure 3.5: Spectrum of atmospheric variability in the North Pacific (details
see text) for November through March averages for the 67 years from 1924 to
1990. Also shown is the corresponding red spectrum with the same lag one
autocorrelation coefficient (0.1) and the 5 and 95% confidence limits. (From
Trenberth and Hurrell, 1994).
