Fig. 1: Niño 3.4 SST power spectra and aerosol and GHG effects on the spectrum peak.

From: Distinct anthropogenic aerosol and greenhouse gas effects on El Niño/Southern Oscillation variability

Fig. 1

a Power spectra of the Niño 3.4 indices of CMIP6 piControl (gray), HIST-AER (blue), and HIST-GHG (red) simulations as well as their 95% confidence limits (dashed/dotted curves). b The averaged energy spectra over a 3-to-5-year period for individual CMIP6 models to construct (a) for their piControl (gray), HIST-AER (blue), and HIST-GHG (red) simulations. c Differences of the averaged energy spectra over the 3-to-5-period between HIST-AER and piControl (HIST-AER minus piControl, green) and between HIST-GHG and piControl (HIST-GHG minus piControl, pink). All panels show the ensemble and multi-model mean results.
