Adhesion theory and model for air humidity impact on dust emission Aeolian Res. (IF 3.3) Pub Date : 2024-02-16 Yaping Shao
It has been suggested that air humidity influences dust emission under very dry conditions and adhesion might be the responsible process which changes the binding between soil particles. The process of adhesion is so far poorly understood and difficult to quantify. Here, a critical examination of the relevant studies is provided, and an adhesion model is proposed. Both isothermal-kinematic and diffusion

Development and validation of vegetation indicators for the occurrence of saltation that consider the spatial distribution of vegetation Aeolian Res. (IF 3.3) Pub Date : 2023-11-24 Akito Kono, Toshiya Okuro
Conventional indicators of vegetation, such as kinds of vegetation and lateral cover, assume spatially homogeneous distribution of vegetation and are insufficient for predicting wind erosion. Conventional indicators for monitoring wind erosion often focus on dust and are not directly related to soil and vegetation, which prevent practitioners from applying monitoring data to rangeland management.

The foreland of the Russian Altai is dominated by the vast Ob loess plateau. The flat landscape exhibits striking linear features, partially more than 100 km in length and tens of km wide. The bottoms of these features are covered by forested dunes, whereas the loess ridges in between are intensively cultivated. To the north, the land cover changes due to gradual transition from the steppe towards

ZIBARS: Distribution, morphology and environmental controls Aeolian Res. (IF 3.3) Pub Date : 2023-01-18 Andrew S. Goudie
Zibar is an Arabic word for aeolian bedforms that are coarse-grained, of limited relief, have no slipfaces, and occur on sand sheets and within interdune corridors of many sand seas. They may also be called granule-armored dunes, undulations, transverse aeolian ridges, mega-ripples, giant ripples, and chevrons and whalebacks. Zibars, though very extensive, are by no means ubiquitous in the world’s

Mineral dust particles suspended in the atmosphere span more than three orders of magnitude in diameter, from <0.1 µm to more than 100 µm. This wide size range makes dust a unique aerosol species with the ability to interact with many aspects of the Earth system, including radiation, clouds, hydrology, atmospheric chemistry, and biogeochemistry.
