Surface thermal patterns of Lake Geneva, Switzerland, from 2008 to 2012

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

In this study we characterize the spatial and temporal variability of the lake surface water temperature (LSWT), lake surface heat fluxes as well as the heat content of Lake Geneva from March 2008 to December 2012. This was accomplished using Advanced Very ...

Seasonal Spatial Patterns of Surface Water Temperature, Surface Heat Fluxes and Meteorological Forcing Over Lake Geneva

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

In many lakes, surface heat flux (SHF) is the most important component controlling the lake’s energy content. Accurate methods for the determination of SHF are valuable for water management, and for use in hydrological and meteorological models. Large lake ...

Heat flux modifications related to climate-induced warming of large European lakes

Alfred Johny Wüest, Martin Schmid

Within the last decades, the water temperature of several European lakes has risen. It is assumed that these temperature increases are due to a reconfiguration of the heat-balance components. This study explores the dominant modifications of heat exchange ...

Prediction of surface temperature in lakes with different morphology using air temperature

Alfred Johny Wüest, Sebastiano Piccolroaz, Marco Toffolon, Martin Schmid

Temperature of the surface layer of temperate lakes is reconstructed by means of a simplified model on the basis of air temperature alone. The comparison between calculated and observed data shows a remarkable agreement (Nash-Sutcliffe efficiency indices a ...

Surface heat flux variability of a large lake: Lake Geneva, Switzerland

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

The heat budget of a lake is a fundamental component of physical limnology, and is strongly dependent on the surface heat flux. However, the surface energy exchange depends on several factors, making it difficult to estimate. In this study we employed seve ...

Wind variability and sheltering effects on measurements and modeling of air-water exchange for a small lake

Fernando Porté Agel, Corey Dean Markfort

Lakes with a surface area of less than 10 km^2 account for over 50% of the global cumulative lake surface water area, and make up more than 99% of the total number of global lakes, ponds, and wetlands. Within the boreal regions as well as some temperate an ...

Metropolitan dynamics and institutional fragmentation in the United States, 1950-2010

Thomas Charles Marie Pierre Favre-Bulle

Since 1950, the United States have witnessed a change in their urban dynamics: the advent of the metropolis. Before, the border was clear between big industrial cities, and small rural communities. At the end of the 19th century, large urban centers starte ...

Wind sheltering of a lake by a tree canopy or bluff topography

Fernando Porté Agel, Corey Dean Markfort

[1] A model is developed to quantify the wind sheltering of a lake by a tree canopy or a bluff. The experiment-based model predicts the wind-sheltering coefficient a priori, without calibration, and is useful for one-dimensional (1-D) lake hydrodynamic and ...

Subgrid-Scale Dynamics of Water Vapour, Heat, and Momentum over a Lake

Ulrich Lemmin, Wolf Hendrik Huwald, Marc Parlange, Charles Vivant Ignacio Meneveau, Nikki Vercauteren

We examine the dynamics of turbulence subgrid (or sub-filter) scales over a lake surface and the implications for large-eddy simulations (LES) of the atmospheric boundary layer. The analysis is based on measurements obtained during the Lake-Atmosphere Turb ...

CO2 exchange between air and water in an Arctic Alaskan and midlatitude Swiss lake: Importance of convective mixing

Alfred Johny Wüest

[1] CO2 exchange between lake water and the atmosphere was investigated at Toolik Lake (Alaska) and Soppensee (Switzerland) employing the eddy covariance (EC) method. The results obtained from three field campaigns at the two sites indicate the importance ...
