Fig. 2: Response of drought events to the source of precipitation deficits.

A Spatial distribution of identified drought events based on total precipitation. Each circle represents a drought event, with its size indicating the severity and colour reflecting the oceanic and continental contribution. B The relationship between the severity of the drought event and the contribution of the source to the drought event. C Box-plots illustrating the distribution of severity and duration of drought events based on the dominant source of the drought event. The vertical lines of each plotted box plot illustrate the 10th, 25th, 75th and 90th quantiles, respectively. The interquartile spread is represented by the range between the 25th and 75th quantiles.
