A Land Potential‐Based Framework for Wind Erosion and Sand and Dust Storm Source Mitigation

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Wind erosion and sand and dust storms are a global challenge. While many management practices to mitigate sources of wind erosion and sand and dust storms have been documented, existing guidance largely emphasizes what practices are available, with limited information on where and under what ecological conditions they should be applied.

Differences in Dust Emission and Near‐Surface Transport Patterns Among Three Surface Substrate Types

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil wind erosion is a major driver of atmospheric dust emissions and land degradation. Many studies have examined dust release from different substrates, but differences in methods and units still limit quantitative understanding of how surface conditions and wind jointly control dust emission and near‐surface transport. A closed‐circuit wind

Rearrangement Towards Stability: Plastic Shakedown in Granular Materials Under Thermal Cycles

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Granular materials are routinely subjected to thermal cycling due to natural and anthropogenic phenomena. Despite the ubiquity of this occurrence and its relevance for science, engineering, and technology, the long‐term thermo‐mechanical response of granular materials to repeated heating and cooling remains poorly understood.

The role of the synoptic‐scale conditions in driving fog and mist during the FATIMA July 2022 Sable Island Field program

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
ERA5 hourly 325‐m and 1512‐m (a) convergence and (b) vertical motion (actually pressure change with sign reversed to compare with convergence) over Sable Island around the time of an event. The mist (green) and fog (red) occurrences at the surface station are shown at the bottom of the figures. A 325‐m fitted line convergence was positive for the first
