In the context of phenomena, “aeolian” refers to physical processes and resulting features driven by the action of wind on unconsolidated or loosely consolidated surface materials, primarily sediments. Aeolian phenomena encompass erosion (deflation and abrasion), transport (suspension, saltation, and surface creep), and deposition, leading to landforms such as dunes, loess deposits, and ripples. These processes are governed by factors including wind velocity and variability, grain-size distribution, surface roughness, moisture content, and vegetation cover. Aeolian dynamics are central to geomorphology and planetary science, contributing to landscape evolution on Earth as well as on other bodies with atmospheres, such as Mars and Titan.
Instead of a winter wonderland, the Red Planet's northern hemisphere goes through an active—even explosive—spring thaw. While New Year's Eve is around the corner here on Earth, Mars scientists are ahead of the game: The Red ...

Long ago, flowing wind and water shaped Mars's malleable sand and sediment into dunes, ripples and other landscape patterns, called bedforms. Over billions of years, some of these landforms hardened into rock—scientists then ...
