Identification of the moisture sources
The annual/seasonal values of (E-P) for 10 days of transport were calculated.
(E-P) fields were calculated for each day [(E-P)n], so e.g., (E-P)7 shows where the air masses gained or lost moisture on the 7th day of transport.
Averaged values of (E-P)1-10 were obtained for the first 10 days of each trajectory.
Figures in this item show the main moisture sources regions with reddish colors, where (E-P)1-10 >0 for the target area.
The moisture source areas were limited by an objective threshold indicated with a magenta contour.
Approach: Backward tracking for the target region
Temporal Scale: Annual and Seasonal
Patterns: (E-P)1-10 and (E-P)n
