Intensity and frequency of short-duration rainfall in Finland
The intensity and local frequency (recurrence interval) of short-duration summer rainfall in Finland is represented in the following graph. The graph can be applied to estimate the probability of heavy rainfall event in a single place. For example, if the rainfall in 15 minutes is 10 mm, the probability for a similar rainfall event in the same place is 25% or, on average, once in every 4 years.
