Correlation coefficients between the annual maximum storm surges (AMTSSs) and (a) Niño-3.4 index, (b) ONI index, (c) Niño 3 index and (d) EMI index at different tide-gauge stations. Circles and squares represent correlations significant and insignificant at 90% confidence level, respectively. Figures were plotted using MATLAB R2018b (http://www.mathworks.com/).
