Figure 4

Wavelet power spectra WPS of each time series (1979–2015): (a) Radon, (b) Water Temperature WT, (c) Discharge rate DR, (d) GCR, (e) Atmosphere Pressure AP, (f) Rainfall. The thick black contour indicates the 95% confidence level and the lighter shade indicates regions inside the cone of influence (COI). The color scale in each panel corresponds to the amplitude of wavelet power spectra.
