DescriptionAbout one third of the atmospheric moisture over the Amazon forest comes from transpiration from the dense canopy and evaporation from soils within the forest. It has been known for decades that between 20% and 40% of the Amazonian precipitation originates from the forest itself. The advent of new methods to quantify the sources of atmospheric moisture and the possibility of adequately visualizing the results, as shown in the exploratory video, led us to the discovery of a characteristic “beating” of the atmospheric moisture of Amazonian origin. Water vapor originating from Amazonian ET ebbs and flows with a characteristic diurnal timescale which becomes evident with our visualization. The timescale is a result of the diurnal cycle of ET, convective precipitation and advection by the winds. These processes come together to form a “beating” pattern that characterizes atmospheric moisture of the Amazon forest.
