Extreme Atmospheric Rivers in a Warming Climate

Figure 1 is the observed and simulated EARs. Figure 2 is EAR response to anthropogenic warming in HR CESM. Figure 3 is EAR response to different warming levels. Figure 4 is landfalling EAR response to anthropogenic warming in HR CESM. Figure 5 is coupling relationship between EARs and ECs. Figure S1 is observed and simulated EAR intensity and occurrence frequency. Figure S2 is simulated EARs in HighResMIP. Figure S3 is comparison of simulated EARs between HR and LR CESM. Figure S4 is sensitivity of EAR projections to ARDTs in HR CESM. Figure S5 is thermodynamic and dynamic EAR responses inHR CESM. Figure S6 is landfalling EAR responses at different stages in HR CESM. Figure S7 is sensitivity of EAR projections to IVT thresholds used to define EARs in HR CESM. Table S1 is the percentage of EARs pairing with ECs in HR CESM.
