The Physics of Snow Crystal Formation

Snow crystals are among the most extraordinary examples of spontaneous pattern formation in nature. Despite their apparent simplicity—water vapor freezing into ice—the resulting morphologies exhibit astonishing diversity, including stellar dendrites, hollow columns, capped columns, needles, plates, and more than one hundred classified types.

Significant Imbalance Between Human Activities and Ecosystem Services in the Tibet Autonomous Region of China: Evidence From an Improved Coupling Coordination Degree Model

Land Degradation &Development, EarlyView.
ABSTRACT Maintaining balanced interactions between humans and ecosystems in plateau regions is critical to achieving global sustainable development. However, existing methodologies are insufficient to fully elucidate the complex coupling and coordination relationships between human activities and ecosystems, as well as the sustainable development ...

Using synthetic models to understand the detecting ability of ground‐penetrating radar for water‐conducting structures in the bedrock of formerly glaciated site

Near Surface Geophysics, EarlyView.
Abstract Utilizing synthetic models for the interpretation of ground‐penetrating radar (GPR) profiles can aid in the detection of hydrogeological structures by identifying their signatures. In this study, finite difference (FD) forward modelling was used to understand the detection ability of 50 MHz GPR for (1) the quaternary deposit–bedrock contact ...

Perceptions of Patients and Health Professionals Regarding the Experience of Patients With a Hybrid Cardiac Rehabilitation Program

Research in Nursing &Health, EarlyView.
ABSTRACT Hybrid cardiac rehabilitation (HCR), which combines supervised center‐based and monitored home‐based exercise programs, gained popularity during the COVID‐19 pandemic. While HCR appears to be as effective as standard cardiac rehabilitation, patients' experiences within these programs remain largely unexplored.

Experimental and field evidence indicate that islet‐nesting tundra birds experience reduced nest predation and benefit indirectly from high snow goose densities

Oikos, EarlyView.
Landscape features can shape the occurrence and strength of predator–prey interactions by influencing predation risk and prey distribution. In the High Arctic, some bird species select nesting sites with physical features that impede access for their main terrestrial predator, the Arctic fox.

Reciprocal relations shape cultural landscapes: Women's environmental stewardship in Ait Bouguemez (High Atlas, Morocco)

People and Nature, EarlyView.
Abstract Mountain social–ecological systems encompass steep ecological gradients and diverse cultural practices, yet the relative roles of these factors in shaping mountain landscapes remain underexplored. In particular, the knowledge and practices of women in coproducing biocultural landscapes are often invisible in the academic literature. In the Ait

Drifting snow. Physical processes and modelling

, 2002
Le transport de neige par le vent entraîne la formation de corniches et de plaques, génératrices d'avalanches en haute montagne, et la formation de congères sur les voies de communication en plaine. Il est de ce fait à l 'origine de risques naturels qui peuvent engendrer de graves conséquences pour les biens et les personnes.

Robust Performance Loss Rate Calculation for Photovoltaic Systems in High Latitude Locations

Progress in Photovoltaics: Research and Applications, EarlyView.
This work studies the best methods for performance loss rate (PLR) calculation in high latitude locations, characterized by strong seasonal variability. As the different methods can drastically affect the PLR value, an ensemble method consisting of multiple approaches was validated to be essential in identifying robust PLRs.

Disposition Model for Permafrost Degradation in Mountainous Regions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.
