Notable
Point Rainfall Events
http://www.bom.gov.au/hydro/has/notables.shtml#comparison%20graph
Records for rainfall in a given time period (ranging from one minute to two years) can be modelled beautifully, and surprisingly, by a power function, so a log-log graph of the data yields a linear model. This website has rainfall records for each of the states in Australia, as well as the world records.
