Meteorological and aerosol effects on marine cloud microphysical properties

Athanasios Nenes, Robin Lewis Modini, Zheng Wang

Meteorology and microphysics affect cloud formation, cloud droplet distributions, and shortwave reflectance. The Eastern Pacific Emitted Aerosol Cloud Experiment and the Stratocumulus Observations of Los-Angeles Emissions Derived Aerosol-Droplets studies p ...

Inferring global wind energetics from a simple Earth system model based on the principle of maximum entropy production

Sami Driss Karkar

The question of total available wind power in the atmosphere is highly debated, as well as the effect large scale wind farms would have on the climate. Bottom-up approaches, such as those proposed by wind turbine engineers often lead to non-physical result ...

Stable Atmospheric Boundary-Layer Flows over a Steep, Alpine Slope: Observations, Theory and Multi-Scale Transport Dynamics

Marc Parlange, Chad Higgins, Holly Jayne Oldroyd, Eric Richard Pardyjak

Katabatic flows are high density air flows traversing down a slope under the action of a gravitational force. These flows can be exploited for wind energy and are gaining importance in predicting scalar transport (e.g. pollutants, water vapor, CO2 drainage ...

A 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 ...

The influence of atmospheric circulation on the mid-Holocene climate of Europe: a data-model comparison

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins

The atmospheric circulation is a key area of uncertainty in climate model simulations of future climate change, especially in mid-latitude regions such as Europe where atmospheric dynamics have a significant role in climate variability. It has been propose ...

Concevoir un quartier à Lucens. Densifier une localité périurbaine tout en conservant et valorisant les échanges entres les habitants (VD)

Valentin Volery

Le projet aborde la question de la densification en milieu rural. L'énoncé a mis en évidence l'évolution morphologique des villages ainsi que celle de sa population. La migration de cette dernière rend difficile son ancrage social et, par conséquent, la pé ...

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 ...

Typical near surface layer current patterns in Lake Geneva’s main basin (Grand Lac)

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Amir Mehdi Razmi

Poster Hall The Lake Geneva current field is controlled by a variable wind field and thermal stratification. Typical current patterns in the Grand Lac which is oriented roughly in the East-West direction were determined under real time wind conditions and ...

Modeling, Simulation, and Performance Evaluation of a Novel Microfluidic Impedance Cytometer for Morphology-Based Cell Discrimination

Philippe Renaud, Ludovica Colella, Marjan Shaker

The performance of a novel microfluidic impedance cytometer [1] for single-cell analysis is investigated in-silico by means of a finite element model. The main feature of the device is the ability to probe impedance of flowing cells along two orthogonal di ...
