The structure and intensity of turbulence in the atmospheric boundary layer (ABL) drive
fluxes of sediment, contaminants, heat, moisture, and CO 2 at the Earth's surface. Where …

Dunes form where winds blow over a bed of mobile sediment grains–conditions that are
common in our solar system. On Earth, dunes abound in arid continental interiors and along …

Wherever a loose bed of sand is subject to sufficiently strong winds, aeolian dunes form at
predictable wavelengths and growth rates. As dunes mature and coarsen, however, their …

The north polar region of Mars, with its greater atmospheric pressure and vast inventory of
ever-changing volatiles (eg, CO 2, H 2 O), hosts arguably the most active and diverse …

The present work employs a predictive model of fluctuating wind velocities constructed on
the basis of long-term field observations to perform trans-scale simulations of aeolian sand …

Wind‐blown sand dunes are both a consequence and a driver of climate dynamics; they
arise under persistently dry and windy conditions, and are sometimes a source for airborne …

Landscapes created through sediment transport are shaped by the interaction of flow and
form. In landscapes where wind is the agent of geomorphic work, this is clear at the small …

Dune fields are self-organized systems shaped by nonlinear and dissipative boundary
conditions. Decoding their environmental history and linking the spatial and temporal …

Landforms such as sand dunes act as roughness elements to Atmospheric Boundary Layer
(ABL) flows, triggering the development of new scales of turbulent motions. These turbulent …

When turbulent boundary layer flows encounter abrupt roughness changes, an Internal
Boundary Layer (IBL) forms. Equilibrium theory breaks down in the nonequilibrium IBL …
