Rainfall patterns can be unpredictable, but statistics help us make sense of them. By analyzing precipitation data, we can understand how often certain storm events occur and plan accordingly.

From frequency analysis to probable maximum precipitation, these tools give us insights into rainfall intensity, duration, and coverage. They're crucial for designing infrastructure and preparing for extreme weather events.

Sounds great, here are the learning objectives I need to cover for the test:

Statistical analysis of precipitation data

Frequency analysis

Frequency distribution Return period Probability Exceedance probability Recurrence interval

Intensity-duration-frequency (IDF) curves

Intensity Duration Frequency Uses of IDF curves

Depth-area-duration (DAD) analysis

Depth Area Duration Uses of DAD analysis

Probable maximum precipitation (PMP)

Definition of PMP Methods to estimate PMP Uses of PMP values
