A wind-albedo-wind feedback driven by landscape evolution

Nature Communications, Published online: 03 January 2020; doi:10.1038/s41467-019-13661-w Wind changes the surface of the Earth, but the surface characteristics of the planet also impact the winds above it. Here, the authors propose a feedback process in which wind erosion in the western Gobi Desert alters the thermal properties of the surface, which in turn increases near-surface winds.
