Aeolian processes and effects

Aeolian processes are the suite of mechanisms by which wind erodes, transports, and deposits sediment, shaping landscapes from coastal dunes to vast desert ergs and leaving records of past climates in layered deposits on Earth and other planets. Understanding how wind mobilizes sand and dust requires untangling the competing roles of surface texture, soil moisture, and vegetation cover, since even sparse plant growth can dramatically anchor sediment and suppress dune migration. Active research is working to quantify how shifting precipitation patterns and land-use change are pushing previously stable dune fields back into motion, contributing to desertification and altering regional dust budgets that affect air quality and ocean productivity. A central open question is how aeolian and fluvial systems interact at their boundaries — where rivers supply sediment that wind then redistributes — and how those coupled dynamics will reorganize under future climate conditions.
