Predicting the morphodynamics of sedimentary landscapes due to fluvial and aeolian flows
requires answering the following questions: Is the flow strong enough to initiate sediment …

Using what has become a celebrated catchphrase, Philip W. Anderson once wrote that
“more is different”(Science, Vol. 177, Issue 4047, pp. 393–396, 1972). First formulated in the …

Sand mobilized by wind forms decimeter-scale impact ripples and decameter-scale or larger
dunes on Earth and Mars. In addition to those two bedform scales, orbital and in situ images …

One-third of the global land area suffers from wind erosion, and its prevention is a critical
issue in arid regions of the world. During a wind erosion event, the impacts of saltating …

Owing to drifting snow processes, snow accumulation and surface density in polar
environments are variable in space and time. We present new field data of manual …

The study of aeolian geomorphological systems over the last half century has advanced
along several important fronts, supported by developments in technologies and analytic …

Desert dust accounts for most of the atmosphere's aerosol burden by mass and produces
numerous important impacts on the Earth system. However, current global climate models …

Wind‐blown sand is the main driver of dune development and dust emission from soils and
is thus of fundamental importance for geomorphology, ecology, climate, and air quality. Even …

The surface of the Earth is snow‐covered at least seasonally over large areas. This snow
surface is highly dynamic, particularly under the influence of strong winds. The motion of …

The surface of Antarctica is continuously shaped by erosion, blowing snow and deposition,
resulting in diverse aeolian bedforms akin to those observed in subtropical sand deserts …
