Background: There is an ongoing need for improved understanding of wildfire plume dynamics.Aims: To improve process-level understanding of wildfire plume dynamics including strong (>10 m s−1) fire-generated winds and pyrocumulus (pyroCu) development.Methods: Ka-band Doppler…

In response to increasing wildfire risks, California plans to expand the use of prescribed fire. We characterized the anticipated change in health impacts from exposure to smoke under a future fire-management scenario relative to a historical period (2008–2016). Using dispersion…

Background: Extreme wildfires have increased in recent decades, yet the consequences of extreme fire behaviour are not fully comprehended. The study of prescribed burning provides opportunities to advance understanding of some overlooked processes in fire behaviour, such as the…

The feasibility of open burning under selected meteorological conditions is discussed. Meteorological provisos and nonmeteorological factors are enumerated. Topics discussed include: combustion, fuel mositure, fire hazard, forecasting, fallout and odor, and air pollution…

Five meshes (1/8 to 1 inch) of 16-gauge steel wire fences, 3 feet high, were tested as possible ground fire barriers in 4 fuel types. The 1/8-inch mesh stopped only 1 test fire but retarded others; 1/4-inch mesh retarded some. The results suggest that further trials may be…

Asphalts and wax emulsions have been recommended as protective coatings to help obtain clean, safe burns in slash disposal work. Fuel value determinations in the laboratory indicate that such coatings add little to the fuel value of slash.

Wildfires, prescribed burns, and agricultural burns all impact ambient air quality across the Western U.S.; however, little is known about how communities across the region are differentially exposed to smoke from each of these fire types. To address this gap, we quantify smoke…

Background: Over the last four decades, wildfires in forests of the continental western United States have significantly increased in both size and severity after more than a century of fire suppression and exclusion. Many of these forests historically experienced frequent fire…
