Figure 4: Gumbel plot for the modelled and observed annual maxima at selected stations.
From: A global reanalysis of storm surges and extreme sea levels

Gumbel plots for five selected stations around the world, (a) Aburatsu, Japan; (b) Boston, United States; (c) Lerwick, United Kingdom; (d) RÃo de Janeiro, Brazil; and (e) Zanzibar, Tanzania. The annual maxima are plotted against the Gumbel variate, which is equal to x=−ln(−ln(G(y))). The red dots in the world map indicate the location of the observation stations.
