In the example below, there were 79 events during the model run given the precipitation graph below.

  • Events: The Events tab shows a table of rank-ordered event periods, including their date, duration, and magnitude ranked according to the mean precipitation intensity.

  • Histogram: The Histogram tab displays a plot of the occurrence frequency versus event magnitude.

  • Frequency Plot: The Frequency Plot tab displays the exceedance frequency of the event values. In the example, below50% of the events had a mean precipitation intensity greater than roughly 0.045.
