Box plots showing the distribution of annual and seasonal maxima of 15-min (Rx15min; top panel), hourly (Rx1h; middle panel), and daily (Rx1d; lower panel) rainfall in the WE-38 watershed; long-term climatological averages are based on 55 years of data from 1968–2022. For each plot, the box indicates the interquartile range, the whiskers show the extreme values (1.5 times the interquartile range), the asterisks designate potential outliers (values greater or less than three times the interquartile range), the solid line depicts the median, and the “x” indicates the mean. Different letters above each box plot indicate significant differences in the medians based on a Kruskal–Wallis analysis followed by Dunn’s post hoc test (p < 0.05). For a comparison of fixed-window vs. moving window results, see Fig. S5 in Supplemental Information.
