Dynamics of wind-induced coastal upwelling and interbasin exchange in Lake Geneva during winter: Implications for deepwater renewal

Water quality in lakes is closely linked to hydrodynamics and often dominated by stratification, limiting the exchange between the epi- and hypolimnion. Thus, the vertical redistribution of biogeochemical tracers such as dissolved oxygen and nutrients by c ...

Estimating the free troposphere measurement quality from high-altitude stations using topographic analysis

Measurements of the Free Troposphere (FT) are important for the study of Climate Change and understanding the Earth’s atmosphere in general. Ground-based, high altitude measurement stations are useful for their ability to collect consistent in situ FT meas ...

A Battery-Less Photovoltaic Water-Pumping System With Low Decoupling Capacitance

Emilio Maddalena

A two-stage photovoltaic water-pumping system architecture is presented in this paper. In contrast with other alternatives available in the literature, the electronic drive does not exploit batteries to accomplish energy decoupling, neither large electroly ...

From the Clouds to the Ground - Snow Precipitation Patterns in Complex Terrain

Varun Sharma, Michael Lehning, Alexis Berne, Franziska Gerber, Marco Gabella, Nikola Besic, Urs Martin Germann

Snow accumulation patterns are determined by many different processes from ice crystal nucleation in clouds to snow redistribution by wind and avalanches. In between, snow precipitation undergoes different dynamical and microphysical processes, such as ice ...

Atmospheric and oceanic climate forcing of the exceptional Greenland ice sheet surface melt in summer 2012

Konrad Steffen

The NASA announcement of record surface melting of the Greenland ice sheet in July 2012 led us to examine the atmospheric and oceanic climatic anomalies that are likely to have contributed to these exceptional conditions and also to ask the question of how ...

Turbulent flow and scalar transport through and over aligned and staggered wind farms

Fernando Porté Agel, Wei Zhang, Corey Dean Markfort

Wind farm-atmosphere interaction is complicated by the effect of turbine array configuration on momentum, scalar and kinetic energy fluxes. Wind turbine arrays are often arranged in rectilinear grids and, depending on the prevailing wind direction, may be ...

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 ...

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 ...

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 ...
