Statistical analysis of inter-arrival times of rainfall events for Italian Sub-Alpine and Mediterranean areas
In this work a set of time-series of inter-arrival times of rainfall events, at daily scale, was analysed, with the aim to verify the issue of increasing duration of dry periods. The set consists of 12 time-series recorded at rain gauges in 1926–2005, six of them belong to an Italian Sub-A...

| description | In this work a set of time-series of inter-arrival times of rainfall events,
at daily scale, was analysed, with the aim to verify the issue of increasing
duration of dry periods. The set consists of 12 time-series recorded at rain
gauges in 1926–2005, six of them belong to an Italian Sub-Alpine area
(Piedmont) and six to a Mediterranean one (Sicily). In order to overcome the
problem related to limited sample size for high values of inter-arrival
times, the discrete probability polylog-series distribution was used to fit
the empirical data from partial (20 yr) time-series. Moreover, a simple
qualitative trend analysis was applied to some high quantiles of
inter-arrival times as well as to the average extent of rain clusters. The
preliminary analysis seems to confirm the issue of increasing duration of
dry periods for both environments, which is limited to the ''cold'' season. |
