Climatological Annual Cycle of the Lagrangian Analysis Components for CGI

(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., 0.05 mm/day) and (b) Schematic representation of the main moisture sources for the RR during 1980–2015: North Pacific Ocean (NPO), Gulf of Mexico (GMX), North Atlantic (NAT),  terrestrial moisture sources surrounding the region (TER), and itself (CGI-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., -0.15 mm/day), and (b) Schematic representation of the terrestrial moisture sink (TER) from each RR.

 
There is no a major sink defined according to the 99th percentile
 

The climatological annual cycle of precipitation (blue line) and moisture supply (grey line) for RR sinks. Scale in mm/day.
