Aeolian processes and effects

Aeolian processes are the mechanisms by which wind shapes Earth's surface: eroding and transporting loose sediment, building dune systems, and delivering mineral dust across continents and oceans. These processes govern landscape evolution across arid and semi-arid regions that cover roughly a third of Earth's land area, and they connect directly to soil degradation, desertification, and the broader carbon and nutrient cycles that regulate climate. A central open question is how vegetation cover and windbreaks modulate dune mobility under shifting precipitation regimes — particularly as climate change alters the thresholds at which stable dune fields reactivate. Researchers are also working to better constrain how aeolian and fluvial systems interact at their boundaries, where sediment handed off between wind and water sets the tempo of landscape change across geologic timescales.
