Abstract
The authors analyse the ultra-centennial series (1833- 1995) of daily total amounts of precipitation recorded in the Genoa University’s Meteorological Observatory and the precipitation annual rates, investigating any relationship with the recent occurrences of exceptional rainfall. Among the principal results there is a constant decrease in the number of rainy days since the first records and a significative jump of precipitation rate since 1950. The application of the Gumbel method to the Return Time of the Annual Maximum (AM) series, owing to the recent anomalous variations of Annual Maximum daily precipitation (mmO24 h), has revealed an increase of heavy rainfall in the last thirty years. Moreover, the return times of these events are remarkably shortened.
