Incorporating an advanced aerosol activation parameterization into WRF-CAM5: Model evaluation and parameterization intercomparison

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

Aerosol activation into cloud droplets is an important process that governs aerosol indirect effects. The advanced treatment of aerosol activation by Fountoukis and Nenes (2005) and its recent updates, collectively called the FN series, have been incorpora ...

A model-based data-interpretation framework for improving wind predictions around buildings

Ian Smith, Didier Vernay

Although Computational Fluid Dynamics (CFD) simulations are often used to assess wind conditions around buildings, the accuracy of such simulations is often unknown. This paper proposes a data-interpretation framework that uses multiple simulations in comb ...

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 ...

Near-inertial waves in Lake Erie

Damien Bouffard

Near-inertial (Poincare) waves with a period T-p similar to 17 h are the dominant wind-induced internal wave motions in central Lake Erie and consequently have a substantial influence on lake circulation, mixing and biogeochemistry. However, due to the com ...

Analysis of the Maximum Efficiency of Kite-Power Systems

Dominique Bonvin, Grégory François, Sean Costello

This paper analyzes the maximum power that a kite, or system of kites, can extract from the wind. Firstly, a number of existing results on kite system efficiency are reviewed. The results that are generally applicable require significant simplifying assump ...

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 ...

Parameterization of bottom mixed layer and logarithmic layer heights in central Lake Erie

Damien Bouffard

The bottom boundary layer in lakes lies directly above the sediments and influences both hydrodynamic processes and biogeochemical fluxes. Several parameter-based models have been developed to predict the boundary layer characteristics, but the relative ac ...

Flow separation at convex banks in open channels

Koen Blanckaert

Laboratory experiments in an open channel bend provide insight into the physics of convex bank flow separation occurring in a variety of channel configurations, including confluences and bifurcations. The edge of the zone of flow separation is characterize ...

A new analytical model for wind farm power prediction

Fernando Porté Agel, Amin Niayifar

In this study, a new analytical approach is presented and validated to predict wind farm power production. The new model is an extension of the recently proposed by Bastankhah and Porte-Agel for a single wake. It assumes a self-similar Gaussian shape of th ...
