Operational snow-hydrological modeling for Switzerland
Frontiers in Earth Science, 2023 The seasonal evolution of snow cover has significant impacts on the hydrological cycle and microclimate in mountainous regions. However, snow processes also play a crucial role in triggering alpine mass movements and flooding, posing risks to people and ...

Hammerhead: a compact 300 kV vacuum bushing
Nature CommunicationsHigh-voltage vacuum bushings are vital for particle accelerators, X-ray tubes, electron microscopes, fusion devices, and electron sources. Commercial bushings, however, are limited to ~ 100 kV, and exceeding this limit has proven to be difficult.

Signatures of the sub-Rayleigh to supershear fracture transition in snow avalanche experiments
Nature CommunicationsSnow slab avalanches occur when a crack propagates within a highly porous weak snow layer buried beneath a cohesive snow slab. Here, we report direct observations of a supershear event in snow fracture experiments following the spontaneous transition ...

Mass balance characteristics of the ‘vanishing’ Rolleston Glacier, New Zealand
Annals of GlaciologyThe 15 years of mass balance monitoring (2010–25) on Rolleston Glacier in the Southern Alps of New Zealand has documented a mass loss of −11.5 m w.e. (−0.8 m w.e. a−1).

Snow instability evaluation: calculating the skier-induced stress in a multi-layered snowpack [PDF]
Natural Hazards and Earth System Sciences, 2016 The process of dry-snow slab avalanche formation can be divided into two phases: failure initiation and crack propagation. Several approaches tried to quantify slab avalanche release probability in terms of failure initiation based on shear stress and ...
