Fig. 4: Correlations between climate modes of variability and extreme wave events.
From: Unveiling the global influence of tropical cyclones on extreme waves approaching coastal areas
Correlations, when significant above 95%, of the yearly number of extreme events a associated to Tropical Cyclones (TCs), b associated to non-TC events, with the El Niño-Southern Oscillation (ENSO) Niño3.4 index (red), Southern Annual Mode (SAM) index (cyan), and North Atlantic Oscillation (NAO) index (orange). Bars are displayed averaged every 200 points for each coastal polygon (see Methods for details on coastal points extraction), and only if correlations exceed 95% significance.
