Precipitation over Northern South America and Its Seasonal Variability as Simulated by the CMIP5 Models

Figure 5

Wavelet power spectrums for seasonal rainfall in the four regions of interest shown in Figure 4 ((a) TRMM, (b) GPCP, (c) CFSR, (d) NorESM1-ME, (e) HadGEM2-ES, (f) GFDLESM2M, (g) FGOALS-g2, and (h) CCSM4). The asterisks indicate the reference datasets. Spectra were obtained from http://paos.colorado.edu/research/wavelets/, based on Torrence and Compo [36].
