Figure 5. Temporal reconstruction of (a) frequencies significant in the El Nino/Southern Oscillation (ENSO) band (summed for 0.1956, 0.2280, 0.2654, 0.2783, and 0.2942 cycles/year) at 2.5oS and 132.5oW (a grid point in the tropical Pacific) and a time series of the NINO3.4 sea-surface temperature (SST) index, (b) frequencies in the decadal band (0.0334, 0.0549 and 0.0898 cycles/year) at 17.5oN and 127.5oW (a grid point in the North Pacific) compared with a time series of the Pacific Decadal Oscillation (PDO), and (c) the multidecadal frequency, 0.0149 cycles/year, compared with the Atlantic Multidecadal Oscillation (AMO) index.
Figure 6. Same as Figure 2 but from a joint MTM-SVD analysis of global sea-surface temperatures and global Palmer Drought Severity Index values. Frequency is in cycles per year (cyc/yr).
