Reading a Probablility Density Function Chart

example of a probablity density functionThis chart shows the range and probability of specific precipitation totals. For example, there is about a 2% chance of getting just 35 inches of precipitation in a year. But if you look at the distribution of rainfall (historical rainfall amounts are shown by the blue bars, while the line graph smooths out this distribution), you can see that most years you are likely to get more precipitation than 35 inches.

Reading a Seasonal Probablility Density Function Chart

This graph shows the range and probability of precipitation totals for each season. Each curve is a statistically-derived, best fit to historical data. The peaks represent rainfall totals with the highest probability; the tails of each curve have very low probability.

Reading a Recurrence Interval Chart

These maps show the percentage of average precipitation that can be expected for a specified length of time and specified return period. You may choose 1- to 5-year accumulation periods and see the probability of specific precipitation totals (on the vertical axis) occurring in a given year. A 100-year return means that there is a 1 in 100 (1%) chance of occurrence in a single year.
