Incorporating a Canopy Parameterization within a Coupled Fire-Atmosphere Model to Improve a Smoke Simulation for a Prescribed Burn

Atmosphere, 2020
Forecasting fire growth, plume rise and smoke impacts on air quality remains a challenging task. Wildland fires dynamically interact with the atmosphere, which can impact fire behavior, plume rises, and smoke dispersion.

Experimental Analysis of a Plume Dispersion Around Obstacles

Energy Procedia, 2015
AbstractNowadays, transport and deposition of aerosol particles (PM2.5, PM10, TSP) caused by industrial plants, environmental applications and transports, are of great concern to public health. Despite the establishment by the European Union of emission standards (European directive 2008/50/CE e.g) to control the limits of particulates in the air, the ...

Investigating the Large-Scale Transport of a Volcanic Plume and the Impact on a Secondary Site

Atmosphere, 2020
Volcanic plumes can be transported across vast distances and can have an impact on solar ultraviolet radiation (UVR) reaching the surface due to the scattering and absorption caused by aerosols.

Coastal circulation and dispersion of passive tracers in the Red River plume region: unveiling seasonal- and intra-seasonal variability [PDF]

Ocean Science
The Red River (RR) plume region of the Gulf of Tonkin (GoT) plays an important role in driving coastal dynamic variability and regulating sediment and nutrient transport and budgets, and is therefore vital for coastal ecosystems and maritime activities ...

Dynamical dispersion in turbulent plumes

, 2018
Experimental observations of turbulent buoyant plumes, produced by a constant source of buoyancy, have been described with great success using a horizontally averaged model for the conservation of mass, momentum and buoyancy flux. However, experimental observations of plumes with time-dependent buoyancy fluxes has proved more challenging for ...

Tritium plume observations in Lake Huron: measurements of dispersion and comparison of lateral plume structure with the normal distribution of the Gaussian Plume Model

Environmental Challenges
This study describes observations of the near-shore transport and dispersion of routine but intermittent tritium emissions from the Bruce Nuclear Generating Station into Lake Huron, which are used as a tracer for inferring dispersion parameters.

Parameterization of vertical dispersion coefficient over idealized rough surfaces in isothermal conditions

Geoscience Letters, 2018
Urban air quality is an important problem nowadays because of the close proximity of sources and receptors in densely built environment. Gaussian plume models have been commonly employed in the industry to estimate air pollution impact over open terrain ...
