Impacts of Climate Change on Snow Avalanche Activity Along a Transportation Corridor in the Tianshan Mountains

International Journal of Disaster Risk Science, 2023
Snow avalanches can repeatedly occur along the same track under different snowpack and meteorological conditions during the snow season in areas of snow avalanche activity.

Dropstones in Lacustrine Sediments as a Record of Snow Avalanches—A Validation of the Proxy by Combining Satellite Imagery and Varve Chronology at Kenai Lake (South-Central Alaska)

Quaternary, 2019
Snow avalanches cause many fatalities every year and damage local economies worldwide. The present-day climate change affects the snowpack and, thus, the properties and frequency of snow avalanches.

Neuronal avalanches differ from wakefulness to deep sleep - evidence from intracranial depth recordings in humans [PDF]

, 2013
Neuronal activity differs between wakefulness and sleep states. In contrast, an attractor state, called self-organized critical (SOC), was proposed to govern brain dynamics because it allows for optimal information coding.

The source, quantity, and spatial distribution of interfacial water during glide-snow avalanche release: experimental evidence from field monitoring [PDF]

The Cryosphere
Glide-snow avalanches release at the soil–snow interface due to a loss friction which is suspected to be linked to interfacial water. Presently, the formation and distribution of the interfacial water are not well understood and glide-snow avalanches are

Automated prediction of wet-snow avalanche activity in the Swiss Alps

Journal of Glaciology, 2023
Wet-snow avalanches are triggered by the infiltration of liquid water which weakens the snowpack. Wet-snow avalanches are among the most destructive avalanches, yet their release mechanism is not sufficiently understood for a process-based prediction ...

Snow avalanche formation [PDF]

Reviews of Geophysics, 2003
Snow avalanches are a major natural hazard, endangering human life and infrastructure in mountainous areas throughout the world. In many countries with seasonally snow‐covered mountains, avalanche‐forecasting services reliably warn the public by issuing occurrence probabilities for a certain region.

Frequency and size change of ice–snow avalanches in the central Himalaya: A case from the Annapurna II glacier

Advances in Climate Change Research
Glaciers have retreated and shrunk in High Mountain Asia since the mid-20th century because of global warming, leading to glacier instability and hazardous ice–snow avalanches.

Station‐Based Assessment of Sub‐Seasonal Climate Trends in the Tyrolean Alps (Austria)

International Journal of Climatology, EarlyView.
In this study, we quantify the magnitude and significance of sub‐seasonal trends in the Tyrolean Alps (Austria) by collecting, processing and analysing meteorological observations from a dense network of climate stations. Our analysis indicates a warming rate of 0.43°C/dec over 1964–2023, greater sub‐seasonal trend variability when the analysis window ...

Calibration and application of the MN2D dynamics model to the avalanches of Las Leñas (Argentina) [PDF]

Natural Hazards and Earth System Sciences, 2002
During the winters of 1999 and 2000 large avalanches occurred in the ski resort of Las Leñas (Los Andes, Mendoza, Argentina). On 8 September 1999 an avalanche of new, dry snow ran over a path with a 1000 m vertical drop. On 30 June and on 1 July 2000

Crack propagation speeds in weak snowpack layers

Journal of Glaciology, 2022
For the release of a slab avalanche, crack propagation within a weak snowpack layer below a cohesive snow slab is required. As crack speed measurements can give insight into underlying processes, we analysed three crack propagation events that occurred ...
