Dust in the Critical Zone: North American case studies
The dust cycle facilitates the exchange of particles among Earth's major systems, enabling
dust to traverse ecosystems, cross geographic boundaries, and even move uphill against …

[HTML][HTML] Complementary classifications of aeolian dunes based on morphology, dynamics, and fluid mechanics
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 …

What sets aeolian dune height?
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 …

Global surface winds and Aeolian sediment pathways on Mars from the morphology of barchan dunes
In the absence of consistent meteorological data on Mars, the morphology of dunes can be
employed to study its atmosphere. Specifically, barchan dunes, which form under …

Local wind regime induced by giant linear dunes: comparison of ERA5-land reanalysis with surface measurements
Emergence and growth of sand dunes results from the dynamic interaction between
topography, wind flow and sediment transport. While feedbacks between these variables are …

The diurnal cycle and temporal trends of surface winds
Y Ashkenazy, H Yizhaq - Earth and Planetary Science Letters, 2023 - Elsevier
Winds play an essential role in the climate system. In this study, we analyze the global
pattern of the diurnal cycle of surface (10 m) winds from the ERA5 reanalysis data. We find …
