Introduction
The first three supplemental figures show the response of each of the CMIP5 models analyzed in
this study, rather than the multi-model average included in the main article. The fourth figure
shows the 21st-century response of one of the CMIP5 models (CCSM4) in its historical and
future simulation of extreme Arctic cyclones.

(corresponds to Figure 2a in main article).
