Temporal Distributions
for 6-, 12-, 24- and 96-hour Durations

  Alaska California
(Click on the map to display the temporal distribution areas for each Volume.)

Temporal distributions of precipitation amounts exceeding precipitation frequency estimates for the 2-year average recurrence interval are provided for 6-, 12-, 24-, and 96-hour durations. The temporal distributions are expressed in probability terms as cumulative percentages of precipitation totals at various time steps. To provide detailed information on the varying temporal distributions, separate temporal distributions were also derived for four precipitation cases defined by the duration quartile in which the greatest percentage of the total precipitation occurred. Unique temporal distributions were derived for each temporal distribution area, which were delineated based on selected extreme precipitation characteristics (see documentation for more details).
