Extended Data Fig. 5: Additive versus multiplicative effects of climate modes phases on coastal flood risks.
From: Climate mode interactions amplify coastal flood risks and their seasonal predictability
Compounding influence of the different phases of ENSO and NAO: Percentage of changes in anomalous extreme CWL conditions during co-occurring phases of climate modes relative to the sum of anomalous extreme CWL conditions during the corresponding individual climate phases (C+ and NAO+ (a), C+ and NAO- (b), E+ and NAO+ (c) and E+ and NAO- (d)). Green, blue, yellow and red dots show the location where the compounded (that is, multiplicative) effects of climate modes (C+ and NAO+ (e), C+ and NAO- (f), E+ and NAO+ (g) and E+ and NAO- (h)) are significant compared to their additive effects at the 50%, 70%, 90% and 95% confidence level respectively based on a Student’s t-test.
