Table 2 Summary of selected flood events between 2010 and 2013. The effects of anthropogenic climate change on flood events (E, enhanced; S, suppressed; N/A, no significant effect) were judged as E (S) when both fraction of attribution (FAR₅₀) scores between ALL and NAT_dtr (dtr) and those between ALL and NAT_CMIP5 (CMIP5) show the same signal. The value of the 10th (90th) percentile of FAR (Table S1) is shown as FAR₉₀ when FAR₅₀ is positive (negative)
