Seawater salinity depends largely on how much moisture is evaporated as winds sweep over the ocean. But pinpointing where the moisture rains back down is a complicated question scientists have long contended with. Scientists have now found a potential path to better seasonal rainfall predictions. Their study shows a clear link between higher sea surface salinity levels in the North Atlantic and increased rainfall on land in the African Sahel.
