Figure 3. Cross-wavelet coherency and phase of the infectious gastroenteritis time series with global climatic indices.

Figure 3

(a) DMI (dipole mode index); (b) MEI (multivariate ENSO index); (c) Niño 1 + 2 (ENSO index); (d) Niño 3 (ENSO index); (e) Niño 4 (ENSO index); (f) Niño 3.4 (ENSO index). Red regions in the upper part of the plots indicate frequencies and times for which the two series share variability. Cone of influence (within which results are not influenced by the edges of the data) and significant coherent time-frequency regions (p < 0.05) are indicated by solid lines. In cross-wavelet phase plots, colors correspond to different lags between the variability in the two series for a given time and frequency, measured in angles from −PI to PI. A value of PI corresponds to a lag of 16 months.
