Influencing Factors of Artificial Snow Particle Size under Natural Environmental Conditions

Zhileng xuebao
In this study, artificial snow is produced under natural conditions using a snowmaking machine, and the microscopic morphology of the snow crystals is obtained.

Study on atomization characteristics of nozzles in artificial snow making process

Zhileng xuebao
The increasing global warming and rapid growth of the ski industry have raised higher demands for artificial snowmaking technology and snow quality, with the quality of artificial snowmaking closely linked to the atomization characteristics of snowmaking

Assessment of the economic risk for the ski resorts of changes in snow cover duration

Лëд и снег, 2015
Winter tourism that is intensively developed in the Russian Federation in recent years strongly depends on the snow availability and properties in the region.

Optimization of methods for assessing the resistance of winter rye to snow mold in natural and artificial infection backgrounds

Аграрная наука Евро-Северо-Востока
Snow mold is an economically important and progressive disease of winter rye caused by several species of low temperature fungi (ascomycetes and basidiomycetes) and fungal-like organisms (oomycetes), with yield losses of up to 30–50 %.

Alternate Methods for the Artificial Release of Snow Avalanches [PDF]

Journal of Glaciology, 1977
Abstract A series of devices have been developed and tested which are designed to initiate the release of snow avalanches by mechanically disturbing or altering the snow cover. These serve as substitutes for the conventional use of high explosives and artillery projectiles.

Wind Tunnel Experiments: Influence of Erosion and Deposition on Wind-Packing of New Snow

Frontiers in Earth Science, 2018
Wind sometimes creates a hard, wind-packed layer at the surface of a snowpack. The formation of such wind crusts was observed during wind tunnel experiments with combined SnowMicroPen and Microsoft Kinect sensors.

Numerical study of fracture arrest on snow cover [PDF]

Fracture and Structural Integrity, 2010
Under the hypothesis of a perfectly brittle phenomenon, avalanche triggering can be investigated numerically by means of Linear Elastic Fracture Mechanics (LEFM).

Soot-on-snow experiment: artificial deposition of light-absorbing particles onto snow surfaces in 2018

Frontiers in Earth Science
The absorption of shortwave irradiance in snow depends on the physical properties of snow (e.g., snow grain size and shape, liquid water content, etc.) and light-absorbing particles (LAP).

Is Our Winter Experience Safe? Micropollutant Risks for Artificial Snowing

Science of The Total Environment
Artificial snowing is a process that allows ski operators adapt to snow scarcity due to climate change while raising environmental and public health concerns about the role it plays in environmental dissemination of pollutants, but studies addressing this question are still scarce.

Explainable machine learning for predictive modeling of blowing snow detection and meteorological feature assessment using XGBoost-SHAP.

PLoS ONE
Accurate forecasting of blowing snow events is vital for improving numerical models of snow processes, yet traditional predictive methods often lack interpretability.
