Ice Cover and Extreme Events Determine Dissolved Oxygen in a Placid Mountain Lake
A decrease in hypolimnetic dissolved oxygen (DO) is a commonly seen effect of climate change. However, in oligotrophic Lake Tovel (Italy), a deep mountain lake, annual mean DO (% saturation) has increased from near anoxia to >20% in the bottom layer (35–39 ...
2020Evaluation of global simulations of aerosol particle and cloud condensation nuclei number, with implications for cloud droplet formation
Athanasios Nenes, Julia Schmale, Yang Yang
A total of 16 global chemistry transport models and general circulation models have participated in this study; 14 models have been evaluated with regard to their ability to reproduce the near-surface observed number concentration of aerosol particles and ...
2019Theoretical and numerical studies of atmospheric boundary-layer flows over complex terrain
Atmospheric boundary-layer (ABL) flows over complex terrain have been the focus of active research, given their impact on weather and climate variability. Surface complexity is understood in a broad sense and includes variation in roughness properties, inc ...
EPFL2016A new wind-farm parameterization for large-scale atmospheric models
Fernando Porté Agel, Mahdi Abkar
In this article, a new model is developed to parameterize the effect of wind farms in large-scale atmospheric models such as weather models. In the new model, wind turbines in a wind farm are parameterized as elevated sinks of momentum and sources of turbu ...
Amer Inst Physics2015Momentum balance of katabatic flow on steep slopes covered with short vegetation
Marc Parlange, Gabriel George Katul, Holly Jayne Oldroyd, Eric Richard Pardyjak
Katabatic flows over alpine mountainous terrain differ from their forested or bare slope counterparts due to the presence of well-ventilated, short vegetation. The impact of a grass canopy and larger-scale pressure perturbations on the one-dimensional mean ...
American Geophysical Union2014Parameterization of cloud droplet formation for global and regional models: Including adsorption activation from insoluble CCN
Dust and black carbon aerosol have long been known to exert potentially important and diverse impacts on cloud droplet formation. Most studies to date focus on the soluble fraction of these particles, and overlook interactions of the insoluble fraction wit ...
Copernicus GmbH2009Simulation of atmospheric flows over complex terrain for wind power potential assessment
When assessing the economic viability of a wind farm, the estimation of the on-site wind power potential is perhaps the most important step. The most common way of evaluating the wind power potential of an area of interest consists of making on-site measur ...
EPFL1998Performances et limites de chaudières à gaz de centrales solaires
Production of electricity from solar energy is mainly achieved by means of solar cells or by central receiver power plants. These plants are driven by vapor turbines where the fluid temperature is about l000°F or by gas turbines in which gas temperature ex ...
EPFL1983Evaluation of global simulations of aerosol particle and cloud condensation nuclei number, with implications for cloud droplet formation
Athanasios Nenes, Julia Schmale, Yang Yang
A total of 16 global chemistry transport models and general circulation models have participated in this study; 14 models have been evaluated with regard to their ability to reproduce the near-surface observed number concentration of aerosol particles and ...
