Climatological Annual Cycle of the Lagrangian Analysis Components for WSA
(a) Climatological annual (evaporation (E) - precipitation (P) > 0) values integrated backward in time over 10 days for the RR region (mm/day). The blue line delimits the moisture sources areas selected using the 95th percentile of the (E-P) > 0 values (i.e., 0.02 mm/day) and (b) Schematic representation of the main moisture sources for the RR during 1980–2015: West Pacific Ocean (WPO), East Pacific Ocean (EPO), North Atlantic (NAT), South Atlantic (SAT), terrestrial moisture sources surrounding the region (TER), and itself (WSA-AR5).
Left-hand column: The climatological annual cycle of: moisture uptake (E - P > 0) integrated over the sources obtained from backward analysis for the RR (top), and moisture contribution (E - P < 0) integrated from the sources to RR estimated through the forward analysis (bottom). Scale in mm/day.
Right-hand column: The percentage of: moisture uptake over the sources obtained for the RR (top), and moisture supply from the source to the RR (bottom).
Climatological annual (evaporation (E) - precipitation (P) < 0) values integrated forward in time over 10 days for the RR region (mm/day). The red line delimits the moisture sink area selected using the 99th percentile of the (E-P) < 0 values (i.e., -0.04 mm/day), and (b) Schematic representation of the terrestrial moisture sink (TER) from each RR.
