Figure 8

The synchronization between dengue incidence and mean temperature between jungle and coastal regions of Perú. Top panels show the wavelet coherence computed using the Morlet wavelet function from the weekly time series of dengue and mean temperature in (a) jungle and (c) coastal regions, respectively. The colors are coded as dark blue, low coherence and dark red, high coherence. The dotted-dashed lines show 5% significance levels computed from 1000 bootstrapped series. The cone of influence indicates the region not influenced by edge effects. Bottom panels show the corresponding oscillating components computed with the wavelet transform in the 0.8-1.2 yr band for (b) jungle (red line) and (d) coastal regions (blue line). The dot-dashed line is the instantaneous time delay in weeks (ΔT) between the oscillating components of two time series. (See [21] for the computation of this delay).
