From: Patterns of change in high frequency precipitation variability over North America
Comparison of the distribution of statistically significant non-zero slopes of P R (y) (a) and L r (y) (b). Boxplot widths are proportional to the number of stations showing a trend for each threshold, which are shown in parenthesis below the threshold. The median and range of slopes and the number of stations showing a trend decrease substantially as the daily minimum threshold increases.
