Water vapor transport in snowpacks

This thesis is an in-depth treatment of water vapor transport in snowpacks and its impacts on snow structure. The aim is to better understand this transport process and to lay the basis for a model representation in physics-based multi-layer snow models. O ...

The impact of secondary ice processes on orographic mixed-phase clouds

Athanasios Nenes, Alexis Berne, Georgia Sotiropoulou, Paraskevi Georgakaki, Etienne Gabriel Henri Vignon

Ground based and airborne observations of orographic mixed-phase clouds (MPCs) forming over mountain top research stations have long reported a discrepancy between the measured ice crystal number concentrations (ICNCs) and the concentration of ice nucleati ...

Changes in Climatology, Snow Cover, and Ground Temperatures at High Alpine Locations

Michael Lehning

Knowledge about changes in ground temperatures under a changing climate is important for many environmental, economic, and infrastructure applications and can be estimated by transient numerical simulations. However, a full annual cycle of precipitation da ...

Nuove ecologie alpine: industrializzazione e costruzione della città-territorio

Roberto Sega

This research study offers a reflection on the Alpine urban condition through the observation of the spaces of production. Departing from the premise that the tourist economy cannot be the only possible horizon for Alpine development, this thesis reflects ...

Adaptations to Climate-Mediated Selective Pressures in Sheep

Stéphane Joost, Sylvie Stucki

Following domestication, sheep (Ovis aries) have become essential farmed animals across the world through adaptation to a diverse range of environments and varied production systems. Climate-mediated selective pressure has shaped phenotypic variation and h ...

Genome-wide patterns of adaptation to climate-mediated selective pressures in sheep

Stéphane Joost, Sylvie Stucki

Sheep (Ovis aries) have been well adapted to thrive in a diverse range of climates during the domestication and breed development process. These climate-mediated selective pressures have shown to influence phenotypic variation within and among breeds and, ...

Vegetation-environment relationships in alpine mires of the West Carpathians and the Alps

Lucia Sekulova

QuestionsHow do two distant mountain ranges differ in their vegetation-environment relationships, overall species composition and its variability and species richness of vascular plants and bryophytes in alpine fens and bogs? Is the floristic difference co ...

Hydrologic response simulation of a snow-covered alpine catchment using a travel time distribution model coupled to alpine3D

Francesco Comola

Fully distributed models of alpine catchment surface processes typically use the geomorphological information provided by digital maps for describing the dynamics of rain, snow, soil and vegetation with much detail. These models are largely used to provide ...

The Uncertainty of Seasonal Snow Energy- and Mass Balance Simulations as a Function of Typical Input Uncertainty

Michael Lehning, Mathias Thierry Pierre Bavay, Charles Fierz

The assessment of water resources and their change in time as well as many other applications from hydrology to meteorology require the successful modelling of the dynamics of the seasonal snow cover. Especially if extrapolation in time, e.g. for climate c ...

Assessment of future snow pack in two Alpine regions

Michael Lehning, Mathias Thierry Pierre Bavay, Sebastian Schlögl

The snow cover in the Alps is heavily affected by climate change. In this study we present an assessment of the future snow water equivalent and snow depth for the Swiss Canton of Graubünden and the Aare catchment in the central Swiss Alps. The data of 48 ...
