  text: Research to detect changes in precipitation variables has become a topic of
    particular interest to understand modifications in water resources availability.
    The review is focused on the Italian territory, outlining the “state of the art”
    of changes in precipitation regime through a review of 54 published studies on
    observed rainfall trend analyses, in the period 1999–2018. The aim is to combine
    a large body of knowledge in a single review and to explain the main patterns
    of rainfall changes occurred in Italy over the last decades. The analysis focused
    on the Total Precipitation (TP) and the number of Wet Days (WDs) indices at the
    annual and seasonal scale. A weight factor is introduced to take into account
    the differences among studies in geographical area, time series length, and number
    of stations. The review is accompanied by the discussion of other rainfall related
    variables, that is, precipitation intensity, extreme rainfall events and meteorological
    droughts, which are useful to provide a broader picture of rainfall changes. Overall,
    there is an agreement about the tendency of a decrease in wet days on the entire
    Italy, with limited discrepancies in the various regions. A decrease in wet days
    is accompanied by a negative trend (although less evident) in total precipitation,
    especially in winter. Nevertheless, a univocal direction of trends (or lack of
    thereof) in annual total precipitation and mostly hydrological extreme events
    is difficult to achieve.
