This paper shows an investigation on temporal and spatial variability of annual maxima of short duration rainfalls (1, 3, 6, 12 and 24 hours) ranging from 1916 to 2000, selected from the rainfall data set of Calabria (southern Italy). To detect changes in the extreme rainfall series the Mann-Kendall non-parametric test has been used at local scale, considering all the stations involved in the region. Moreover the variability of both parameters and quantiles of empirical intensity-duration-frequency relationships for short duration rainfalls has been explored for different time periods. Finally the monthly distribution of the occurrence process of annual maxima of short duration rainfalls has been statistically analysed.
