Rainfall Return Levels

33 years, 1963 to 1999

Rainfall return levels at Prata Do Piaui: the daily rain expected about once in a given number of years

50 years132.6 mm (5.2 in)Longer than the 33 years of record
100 years138.5 mm (5.5 in)Longer than the 33 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 33 years of values from 1963 to 1999.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 137.7 mm (5.4 in) in 1997; 124.0 mm (4.9 in) in 1994; 116.2 mm (4.6 in) in 1992.
