- Abstract
- The present study aims at improving data availability and quality for the last 80-90 years for daily
precipitation in the Calabria region (southern Italy). First, the original database was homogenised and the gaps filled
in for 129 daily rain gauges for the 1916-2006 period. Then, precipitation variability and change were evaluated at an
adequate spatial resolution. Monthly and annual total precipitation (P), number of wet days (WDs), and precipitation
intensity (PI) were calculated for each series. With regard to the monthly total precipitation a general negative trend, albeit
not everywhere significant, was detected, in particular for the autumn-winter period, while in summer the tendency was
toward an increase in total precipitation. The monthly behaviour of WDs was not very different from that observed for P:
a diffuse negative trend was detected in most months, particularly evident and significant in January, with the exception
of April and the summer months, for which the tendency was toward an increase. Regarding the PI, a general negative
and often significant trend was found for the entire region and for almost all the months, except summer. Attention was
also focused on tendencies in the different PI categories, revealing negative trends in high-intensity categories, especially
coming from the winter season.
Finally, running trend analysis revealed that the previously discussed tendencies were not persistent throughout the series
length, but depended on the period examined. This important aspect should be taken into account when different results
based on different time windows are compared. (literal)
