Technical Note: Sensitivity of 1-D smoke plume rise models to the inclusion of environmental wind drag
Vegetation fires emit hot gases and particles which are rapidly transported upward by the positive buoyancy generated by the combustion process. In general, the final vertical height that the smoke plumes reach is controlled by the thermodynamic stability of the atmospheric environment and the surface heat flux released by the fire. However, the presence of a strong horizontal wind can enhance ...
متن کاملWildland fire emissions, carbon, and climate: Plume rise, atmospheric transport, and chemistry processes
This paper provides an overview and summary of the current state of knowledge regarding critical atmospheric processes that affect the distribution and concentrations of greenhouse gases and aerosols emitted from wildland fires or produced through subsequent chemical reactions in the atmosphere. These critical atmospheric processes include the dynamics of plume rise, chemical reactions involvin...
متن کاملResolving intercontinental pollution plumes in global models of atmospheric transport
[1] Synoptic-scale pollution plumes in the free troposphere can preserve their identity as well-defined structures for a week or more while traveling around the globe. Eulerian chemical transport models (CTMs) have difficulty reproducing these layered structures due to numerical plume dissipation. We show that this dissipation is much faster than would be expected from the order of the advectio...
متن کاملModeling Smoke Plume-Rise and Dispersion from Southern United States Prescribed Burns with Daysmoke
We present Daysmoke, an empirical-statistical plume rise and dispersion model for simulating smoke from prescribed burns. Prescribed fires are characterized by complex plume structure including multiple-core updrafts which makes modeling with simple plume models difficult. Daysmoke accounts for plume structure in a three-dimensional veering/sheering atmospheric environment, multiple-core updraf...
متن کاملMulti-pollutant Plume-in-grid Modeling
One-atmosphere three-dimensional (3-D) grid models are now being widely used to predict the impacts of emission controls on the atmospheric concentrations and deposition of pollutants such as ozone (O3), fine particulate matter (PM2.5), mercury (Hg) and other air toxics. Such a gridbased approach necessarily averages emissions within the volume of the grid cell where they are released. This ave...
