Seasonal trends and temperature dependence of the snowfall/precipitation-day ratio in Switzerland

This paper analyzes the proportion of snowfall days relative to precipitation days, in order to assess the impact of changing temperatures on snowfall, while minimizing the impact of variations in precipitation frequency and intensity. We analyzed the rati ...

The influence of winds, sea-surface temperature and precipitation anomalies on Antarctic regional sea-ice conditions during IPY 2007

Katherine Colby Leonard

The 2007 International Polar Year (IPY) in the Antarctic was distinguished by strong regional and seasonal ice-atmosphere-ocean anomalies associated with an overall weakening of the prevailing westerly circulation. Here we assess the ice-atmosphere-ocean c ...

Evaluating Error Propagation in Coupled Land-Atmosphere Models

Dasaraden Mauree

This study examines how land-use errors from the Land Transformation Model (LTM) propagate through to climate as simulated by the Regional Atmospheric Model System (RAMS). The authors conducted five simulations of regional climate over East Africa: one usi ...

Long-term changes in annual maximum snow depth and snowfall in Switzerland based on extreme value statistics

Juliette Ferial Blanchet

Mountain snow cover is an important source of water and essential for winter tourism in Alpine countries. However, large amounts of snow can lead to destructive avalanches, floods, traffic interruptions or even the collapse of buildings. We use annual maxi ...

Fiber optic distributed temperature sensing for the determination of the nocturnal atmospheric boundary layer height

Wolf Hendrik Huwald, Marc Parlange

A new method for measuring air temperature profiles in the atmospheric boundary layer at high spatial and temporal resolution is presented. The measurements are based on Raman scattering distributed temperature sensing (DTS) with a fiber optic cable attach ...

Magnitude and seasonality of wetland methane emissions from the Hudson Bay Lowlands (Canada)

Jed Oliver Kaplan, Isabelle Bey, Jérôme Drevet

The Hudson Bay Lowlands (HBL) is the second largest boreal wetland ecosystem in the world and an important natural source of global atmospheric methane. We quantify the HBL methane emissions by using the GEOS-Chem chemical transport model to simulate aircr ...

Force-induced desorption of self-avoiding walks on Sierpinski gasket fractals

Stevan Arsenijevic

In this work we investigate force-induced desorption of linear polymers in good solvents in non-homogeneous environment, by applying the model of self-avoiding walk on two- and three-dimensional fractal lattices, obtained as generalization of the Sierpinsk ...

Modelling of spandrel elements in URM structures with RC slabs or ring beams

Katrin Beyer, Alessandro Dazio

In many unreinforced masonry (URM) buildings reinforced concrete (RC) slabs or ring beams maintain the integrity of the building when subjected to seismic loading and redistribute forces between different URM piers. In addition, RC slabs and ring beams con ...

Advanced cyclic coding technique for long-range Raman DTS systems with meter-scale spatial resolution over standard SMF

Marcelo Alfonso Soto Hernandez

A long-range fast-measurement Raman-based distributed temperature sensor (RDTS) with a meter spatial resolution exploiting a quasi-periodic pulse-coding technique is proposed in this paper. We experimentally demonstrate the feasibility of temperature sensi ...

Effects of Colonization Asymmetries on Metapopulation Persistence

Olivier Lévêque, Séverine Vuilleumier Varisco

Ocean currents, prevailing winds, and the hierarchical structures of river networks are known to create asymmetries in re-colonization between habitat patches. The impacts of such asymmetries on metapopulation persistence are seldom considered, especially ...
