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
