Fig. 7: Mean moisture uptake cells (g/kg) calculated with the HYSPLIT model for four sites characterised by different behaviours.

a Point 1; b Point 3; c Point 13; d Point 8. The maps show the spatial distribution of average moisture uptake along the back-trajectories associated with each site. e reports the map of the arrival locations of the trajectories considered in the analysis (1–17). The colour scale indicates the mean intensity of moisture uptake, from lower values (light blue) to higher values (dark blue). Basemap: OpenStreetMap contributors.
