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 ...

Optical-microphysical properties of Saharan dust aerosols and composition relationship using a multi-wavelength Raman lidar, in situ sensors and modelling: A case study analysis

Athanasios Nenes

A strong Saharan dust event that occurred over the city of Athens, Greece (37.9° N, 23.6° E) between 27 March and 3 April 2009 was followed by a synergy of three instruments: a 6-wavelength Raman lidar, a CIMEL sun-sky radiometer and the MODIS sensor. The ...

Measurement and modeling of Vidy Bay (Lake Geneva) hydrodynamics

David Andrew Barry, Ulrich Lemmin, Amir Mehdi Razmi

Vidy Bay is located near Lausanne on the northern shore of Lake Geneva in an area where sewage outfalls and drinking water intakes are positioned. Local circulation patterns may control water quality aspects in this part of lake. Currents are mainly influe ...

Vidy Bay hydrodynamics under typical meteorological conditions

David Andrew Barry, Ulrich Lemmin, Amir Mehdi Razmi

Vidy Bay (Lake Geneva, Switzerland) is the site of a sewage outfall, located 700 meters offshore at a depth of 30 meters. Estimates of water circulation in this area are required to assess the transport and fate of water quality components. Numerical simul ...

Thermal Circulation Patterns and Turbulent Fluxes along Steep Mountain Slopes

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau, Fabian Bärenbold

In hydrology, it is crucial to understand the atmospheric flow dynamics in mountainous terrain to predict turbulent exchanges of heat and moisture accurately at the regional scale. Under clear skies and weak synoptic conditions, these land–atmosphere inter ...

Size-resolved CCN distributions and activation kinetics of aged continental and marine aerosol

Athanasios Nenes, Spyros Pandis

We present size-segregated measurements of cloud condensation nucleus (CCN) activity of aged aerosol sampled at Finokalia, Crete, during the Finokalia Aerosol Measurement Experiment of summer 2007 (FAME07). From analysis of the data, hygroscopicity and act ...

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 ...

Thermal Circulation Patterns and Turbulent Fluxes along Steep Mountain Slopes

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau, Eulalie Sauthier, Fabian Bärenbold

In hydrology, it is crucial to understand the atmospheric flow dynamics in mountainous terrain to predict turbulent exchanges of heat and moisture accurately at the regional scale. Under clear sky and weak synoptic conditions, these land–atmosphere interac ...

On the link between ocean biota emissions, aerosol, and maritime clouds: Airborne, ground, and satellite measurements off the coast of California

Athanasios Nenes

Surface, airborne, and satellite measurements over the eastern Pacific Ocean off the coast of California during the period between 2005 and 2007 are used to explore the relationship between ocean chlorophyll a, aerosol, and marine clouds. Periods of enhanc ...

Long-Range Transport to Europe : Seasonal Variations and Implications for the European Ozone Budget

Isabelle Bey, Marion Auvray

We use a chemical transport model (GEOS-CHEM) to quantify the contribution of long-range transported pollution to the European ozone ({O}{3}) budget for the year 1997. The model reproduces the main features observed over Europe for {O}{3}, carbon monoxid ...
