Origin and fate of atmospheric moisture over continents

摘要: There has been a long debate on the extent to which precipitation relies terrestrial evaporation (moisture recycling). In past, most research focused moisture recycling within certain region only. This study makes use of new definitions complete process continental feedback. Global maps are presented identifying regions that rely heavily recycled as well those supplying moisture. An accounting procedure based ERA‐Interim reanalysis data is used calculate ratios. It computed that, average, 40% originates from land and 57% all returns over land. Moisture evaporating Eurasian continent responsible for 80% China’s water resources.
