Event-driven deposition of snow on the Antarctic Plateau: analyzing field measurements with SNOWPACK

Antarctic surface snow has been studied by means of continuous measurements and observations over a period of 3 yr at Dome C. Snow observations include solid deposits in form of precipitation, diamond dust, or hoar, snow temperatures at several depths, rec ...

Wind Tunnel Studies of Shear Stress Partitioning in Live Plant Canopies

Benjamin Andreas Walter

The earth's surface is permanently exposed to the atmosphere and accordingly to strong wind forces in many regions. Aerodynamic entrainment, transport and redeposition of sand, soil or snow are able to considerably reshape the surface morphology and influe ...

Stochastic Generation of Wind Patterns over Lake Geneva

David Andrew Barry, Ulrich Lemmin, Amir Mehdi Razmi, Nicolas Le Dantec, Caitlin Ellen Barry

Lake Geneva (length 74 km on the long east-west axis, surface area 562 km2, volume 89 km3) is a freshwater lake bordered by Switzerland and France. The lake’s hydrodynamics are forced principally by wind and seasonality, with inflows and the Coriolis effec ...

Micrometeorological and morphological observations of surface hoar dynamics on a mountain snow cover

Michael Lehning, Charles Fierz

The formation, growth, and destruction of surface hoar crystals is an important feature of mountain snow covers as buried surface hoar layers are a frequent weak layer leading to unstable snowpacks. The energy and mass exchange associated with surface hoar ...

Increasing storm damage to forests in Switzerland from 1858 to 2007

Martine Rebetez

The most severe damage to forests in Central Europe occurs during winter storms caused by Northern Hemispheric mid-latitude cyclones. Storm events in the winter semesters of the past 150 years were investigated to quantify changes and evaluate whether dama ...

The influence of local meteorological conditions on the circadian rhythm of corn (Zea mays L.) pollen emission

Marc Parlange

Field experiments were performed to study the diurnal cycle of corn pollen emission and its relation to local meteorological conditions, including temperature, relative humidity, solar radiation, mean wind speed, and turbulence quantities. Pollen concentra ...

A new approach for studying small scale turbulence in the thermocline region of Lake of Geneva

Damien Bouffard

The aim of this PhD thesis is to contribute to a better understanding of turbulent mixing in lakes. This research is focused on the response dynamics of the stratified Lake of Geneva to strong wind forcing. We especially investigated the dynamics of small ...

Measurement and simulation of viscous dissipation in the wave affected surface layer

Alfred Johny Wüest

In this study we compare turbulence parameters from field observations and model simulations specifically under the influence of weak to moderate wind forcing and breaking short waves. The experiment was performed during 12 days under very weak stratificat ...

Sediment distribution on a current-dominated lake delta (Versoix delta, Lake Geneva, Switzerland)

Ulrich Lemmin

Lake delta morphology is determined by fluvial input, waves, lake currents, lake-level fluctuations and lake-basin topography. The current-dominated Versoix delta (Petit-Lac of Lake Geneva, Switzerland), has been studied in order to determine the role of w ...

Effect of sea breeze on air pollution in the greater Athens area. Part I: Numerical simulations and field observations

Hubert van den Bergh, Bertrand Calpini, Alain Clappier

Numerical simulations compared with field measurements are used to explain the effect of sea breezes on photochemical smog episodes in Athens during the Mediterranean Campaign of Photochemical Tracers on 12-14 September 1994. The numerical simulations, per ...
