Short summary
Snow cornices lead to the potential risk of causing snow avalanche hazards, which are still unknown so far. We carried out a wind tunnel experiment in a cold lab to investigate the environmental conditions for snow cornice accretion recorded by a camera. The length growth rate of the cornices reaches a maximum for wind speeds approximately 40 % higher than the threshold wind speed. Experimental results improve our understanding of the cornice formation process.

Short summary
Sand and dust emission are usually investigated by wind-tunnel experiments. However, wind-tunnel flows are usually neutrally stratified without large eddies, which typically develop in the convective atmospheric boundary layer. Here we proposed a novel technique by deploying a piece of randomly fluttering cloth in a wind tunnel to generate the large eddies and found them to enhance the entrainment of sand and dust particles, which explains why large eddies are important to aeolian entrainment.

Through a series of numerical experiments using the large-eddy-simulation model, we have developed an improved particle deposition scheme that takes into account transient wind shear fluctuations. Statistical analysis of the simulation results shows that the shear stress can be well approximated by a Weibull distribution and that the new scheme provides more accurate predictions than the conventional scheme, particularly under weak wind conditions and strong convective atmospheric conditions.

Short summary
Cornices are overhanging snow accumulations that form on mountain crests. Using wind-tunnel experiments and high-speed photography, the study tracks particle trajectories around cornices and finds distinct differences between edge and surface deposition. A static adhesion model for edge deposition was developed and validated to predict how particle size and shape affect adhesion. The work clarifies the microdynamics of early cornice growth and provides a foundation for avalanche modeling.

Short summary
Particle fragmentation makes snowflakes spherical during wind-drifting snow. However, no drifting snow model has presented this process so far. We established a drifting snow model considering particle fragmentation and investigated the effects of snow particle fragmentation on drifting and blowing snow. Our results show that fragmentation intensifies the sublimation of blowing snow and changes the airborne particle size distribution, which should not be ignored in current blowing snow models.

Short summary
Snow cleans air as falling snow captures dust. We studied how wind turbulence affects this process. Our computer simulations reveal that turbulence makes snow particles move horizontally, greatly increasing their dust collection. Current models ignore this horizontal motion and thus underestimate cleaning. Our new model captures this effect, offering a better tool for predicting air pollution removal and guiding environmental cleanup efforts.
