However, in many
of the same places, actual evapotranspiration inferred
from surface
water balance exhibits an increase in association with enhanced soil wetness
from increased precipitation, as the actual evapotranspiration becomes closer to the potential

(Evapotranspiration is the process by which
water is transferred
from soil and groundwater to the atmosphere through plant transpiration — loss

Hatun et al. examined the possibilities that [i] a change in rain falling over the ocean (freshens the
water) and
evaporation (increases the salinity by removing
water and leaving salt behind), [ii] increased salinity in the sub-tropical gyre (in the main part
of the North Atlantic), [iii] increased salinity in the sub-polar gyre, or [iv] dynamical changes in the relative contributions
from the two gyres could explain the high salinities in the in - flow regions.
