Smoke Emissions from Wildland Fires
Biomass burning is a major source of emissions to the atmosphere. Some of these emissions may change global climate. This paper uses combustion eff iciency as an independent variable for predicting emission factors for, among others, carbon monoxide, carbon dioxide, methane, and particulate matter. Other gases are correlated with the release of carbon monoxide. The release of nitrogen and sulfu...
متن کاملLightning response to smoke from Amazonian fires
[1] The effect of anthropogenic aerosols on clouds has the potential to be a key component for climate change predictions, yet is one of the least understood. It is possible that high aerosol loading can change the convection intensity and hence the electrical activity of thunderstorm clouds. Focusing on the Amazon dry season, where thousands of man‐made forest fires inject smoke into the atmos...
متن کاملGlaciation activity of desert dust, air pollution and smoke from forest fires in convective clouds
The heavy air pollution, known as Atmospheric Brown Cloud (ABC), has been research mainly for its radiative effects and cloud condensation nuclei (CCN) activity that act to nucleate larger number of smaller cloud drops, and hence suppress coalescence and warm rain forming processes (Ramanathan et al., 2001). Precipitation in convective clouds with aerosol-induced suppressed coalescence is initi...
متن کاملEmissions from Forest Fires Near Mexico City
The emissions of NOx (defined as NO (nitric oxide) + NO2 (nitrogen dioxide)) and hydrogen cyanide (HCN), per unit amount of fuel burned, from fires in the pine forests that dominate the mountains surrounding Mexico City (MC) are about 2 times higher than normally observed for forest burning. The ammonia (NH3) emissions are about average for forest burning. The upper limit for the mass ratio of ...
متن کاملSmoke movement for sprinklered fires
This paper presents the initial results of a project initiated by the American Society of Heating, Refrigerating and AirConditioning Engineers (ASHRAE) and the National Research Council of Canada to investigate smoke movement resulting from a sprinklered fire in a communicating space into an adjacent large open area such as an atrium or retail mall. Recent research on the interaction of sprinkl...
