Improving local wind estimation for the automated control of blinds

Jean-Louis Scartezzini, Dasaraden Mauree, Laurent Deschamps, Ali Motamed

Blinds are usually installed on building façade to improve the visual and thermal comfort of the oc-cupants. They are now often linked to an automat-ed system that helps control the glare and decrease overheating. These automated systems are linked to a we ...

Analysis of the variation of the 0°C isothermal altitude during intense rainfall events

Anton Schleiss, Javier García Hernández, Bettina Schaefli, Fränz Zeimetz

The analysis aims at analysing the evolution of the 0°C isothermal altitude during intense rainfall events. The following steps are followed: • The rainfall events of around 100 meteorological stations measuring at hourly time step are considered. • Two me ...

Sensitivity of simulated summer monsoonal precipitation in Langtang Valley, Himalaya, to cloud microphysics schemes in WRF

Margaux Caroline Patricia Couttet

A better understanding of regional-scale precipitation patterns in the Himalayan region is required to increase our knowledge of the impacts of climate change on downstream water availability. This study examines the impact of four cloud microphysical sche ...

How much can we save? Impact of different emission scenarios on future snow cover in the Alps

Michael Lehning, Mathias Thierry Pierre Bavay, Sebastian Schlögl

This study focuses on an assessment of the future snow depth for two larger Alpine catchments. Automatic weather station data from two diverse regions in the Swiss Alps have been used as input for the Alpine3D surface process model to compute the snow cove ...

Modeling regional air quality and climate: Improving organic aerosol and aerosol activation processes in WRF/Chem version 3.7.1

Yi Zhang, Athanasios Nenes

Air quality and climate influence each other through the uncertain processes of aerosol formation and cloud droplet activation. In this study, both processes are improved in the Weather, Research and Forecasting model with Chemistry (WRF/Chem) version 3.7. ...

Temporal evolution of crack propagation propensity in snow in relation to slab and weak layer properties

Johan Alexandre Philippe Gaume, Jürg Schweizer, Alec van Herwijnen

If a weak snow layer below a cohesive slab is present in the snow cover, unstable snow conditions can prevail for days or even weeks. We monitored the temporal evolution of a weak layer of faceted crystals as well as the overlaying slab layers at the locat ...

Wind Energy Potential in Switzerland: Discovering Localized Thermo-topographic Flows and Associated Wind Resource

Varun Sharma, Michael Lehning, Franziska Gerber

In 2011, the Swiss Federal council and Parliament decided on the phase out of Switzerland’s five nuclear energy plants (BFE n.d.) and launched the “Energy Strategy 2050” which envisages a significant expansion of electricity production from renewable sourc ...

Examining Building Design Decisions Under Long Term Weather Variability and Microclimatic Effects: A case-based exploratory study

Marilyne Andersen, Luisa Pastore, Parag Rastogi, Margaux Marie Valérie Peltier, Minu Agarwal

Thermal building simulation currently uses Typical Meteorological Year (TMY) data to guide the design decision-making process or for compliance with energy standards. TMY data usually excludes extremes and in many cases are gathered from microclimatic cont ...

A radar-based regional extreme rainfall analysis to derive the thresholds for a novel automatic alert system in Switzerland

Alexis Berne, Marco Gabella, Urs Martin Germann, Luca Panziera

This paper presents a regional extreme rainfall analysis based on 10 years of radar data for the 159 regions adopted for official natural hazard warnings in Switzerland. Moreover, a nowcasting tool aimed at issuing heavy precipitation regional alerts is in ...

Incorporating an advanced aerosol activation parameterization into WRF-CAM5: Model evaluation and parameterization intercomparison

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

Aerosol activation into cloud droplets is an important process that governs aerosol indirect effects. The advanced treatment of aerosol activation by Fountoukis and Nenes (2005) and its recent updates, collectively called the FN series, have been incorpora ...
