Sensitivity of the Global Water Cycle to the Water-Holding Capacity of Land

摘要: Abstract The sensitivity of the global water cycle to water-holding capacity plant-root zone continental soils is estimated by simulations using a mathematical model general circulation atmosphere, with prescribed ocean surface temperatures and cloud. With an increase globally constant storage capacity, evaporation from continents rises runoff falls, because high enhances ability soil store periods excess for later during shortage. In addition this direct effect, atmospheric feedbacks associated resulting higher precipitation lower potential drive further changes in runoff. Most occur tropics northern middle-latitude rain belts. Global land increases about 7 cm each doubling range less than 1 almost 60 cm. Sensitivity ...
