Human activities have determined deep changes in the global water cycle, with significant effects on the availability and quality of hydrological resources. This study investigates the dynamics of atmospheric moisture and hydrological connectivity in Italy and in three regions (Piemonte, Lazio, Sicily) through the analysis of two main concepts: evaporationsheds – that is, the downwind areas where the precipitations supplied by the evaporation in the region of interest occur – and precipitationsheds – that is, the upwind areas from which the evaporation contributing to precipitations in the region of interest originates. The study has been implemented through the use of two different datasets: UTrack – a Lagrangian atmospheric moisture tracking model developed by Tuinenburg et al.
