Estimating the effective elastic modulus and specific fracture energy of snowpack layers from field experiments

Journal of Glaciology, 2016
Measurements of the mechanical properties of snow are essential for improving our understanding and the prediction of snow failure and hence avalanche release. We performed fracture mechanical experiments in which a crack was initiated by a saw in a weak

Elevation shapes alpine snow algal blooms and their influence on albedo reduction

New Phytologist, Volume 251, Issue 5, Page 2482-2496, September 2026.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

Modelling High‐Alpine Karst Runoff With Coupled Snow Models of Different Complexity Levels at Mount Zugspitze

Hydrological Processes, Volume 40, Issue 8, August 2026.
Two hydrological model configurations with contrasting snow process complexity were evaluated in a high‐alpine, snow‐dominated karst catchment (2014–2025) at Mount Zugspitze (Germany). Despite comparable discharge simulation performance and water balances, the models show substantial differences in internal process representation.

Glacier Mass Balance Modeling Using a Long Short‐Term Memory Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Glacier mass balance (MB) is a key indicator of climate change and a central driver of glacier evolution, yet most glaciers worldwide lack long‐term in situ measurements. For estimating glacier MB, data‐driven models provide a complementary alternative to traditional numerical approaches by learning empirical relationships between climate ...

The Performance Gains of Assimilating Limited Information Into a Fully Distributed Snowpack Model Depend on Model Complexity and Input Data Quality

Water Resources Research
Estimating snowpack conditions in mountainous regions is critical for water resource management, flood forecasting, and avalanche hazard mitigation. However, most snowpack observations lack either spatial or temporal resolution, while estimates from ...

Glide-snow avalanches: a mechanical, threshold-based release area model [PDF]

Natural Hazards and Earth System Sciences
Glide-snow avalanches release at the ground–snow interface due to a loss in basal friction. They pose a threat to infrastructure because of the combination of unreliable mitigation measures, limited forecasting capabilities, and a lack of understanding ...

Beyond temperature: The environmental constraints of high‐mountain microrefugia

Journal of Ecology, Volume 114, Issue 8, August 2026.
Cold spots in an alpine landscape often sit on poor, rocky, carbon‐low soils rather than well‐developed ground. As climate warms, alpine plants may find these cold refuges too harsh to colonize, since many depend on richer soils than nival and subnival species do.

Experimental investigation of dielectric properties of seasonal snow at field observatories in the northwest Himalaya

Annals of Glaciology, 2016
Radio-echo sounding techniques are very useful for fast profiling of seasonal snowpack. Ground-penetrating radar (GPR) is used widely for various cryospheric applications, such as snow/glacier depth estimation, snow layer identification and snow water ...

Snow and Avalanche Conditions at Mt. Baldy, California

, 1966
The winter recreation area of Mt. Baldy presents some unusual snow, weather and avalanche conditions. The snow ranger\u27s task of insuring public safety on this part of the Angeles National Forest is compounded by the proximity of the huge Los Angeles ...
