The meridional variability of the components of moisture exchange between the ocean and the atmosphere in the northern Atlantic

Output from Reanalysis ۲ is used to express the temporal and spatial variations of rainfall, evaporation on the North Atlantic. This archive has been used for the years ۱۹۸۰-۲۰۱۶ within ۳۰۰N-۷۰۰N. The difference between E and P is the net freshwater flux, which directly affects salinity and thus classifies the ocean surface layers. In mean annual, P exceeds E in the North Atlantic poleward of ۵۰۰N; E exceeds P between ۲۰۰N and ۵۰۰N as well as in the eastern Atlantic Ocean (۱۰۰N-۳۵۰N). Seasonal changes are significant among the regions: s: P and E both peak during the cold period (October-March) in the subpolar region, also P and E values are close in the warm cold period at latitude ۴۱۰N, so that in the warm period, their difference approaches zero.
