Abundant charcoal in forest soils gives evidence of prehistoric and historic natural and anthropogenic wildfires in perhumid lowland and in seasonal Dipterocarp forest types of continental and insular South Asia. Favorable conditions for the occurrence of historic and…

From the text...'Given the concerns presented over the relative lack of progress being made in restoring fire to anything close to presettlement frequencies, it is only natural to ask what can we expect in the future. Although it is impossible to read the crystal ball, it is…

The mesoscale meteorological model MEMO was applied to a real fire situation, which occurred in the central area of Portugal, with a very complex topography. In order to numerically provide boundary values at a higher temporal and spatial resolution, a one-way nesting technique…

A large eddy simulation (LES) model of smoke plumes generated by large outdoor pool fires is presented. The plume is described in terms of steady-state convective transport by a uniform ambient wind of heated gases and particulate matter introduced into a stably stratified…

Forest management planning models are highly developed and used extensively, but few explicitly consider the effects of fire and other uncertain losses which can be significant. Previous studies recommended contradictory responses to potential fire loss. We developed forest-…

We begin our study of wildland fire with the basic principles and mechanisms of the combustion process-fire fundamentals. In the next chapter we look at wildland fire as an event. Fire behavior is what a fire does, the dynamics of the fire event. In later chapters we move up the…

The Atmospheric Boundary Layer (ABL) is the lowest portion of the Earth's atmosphere which is affected significantly by the properties of the Earth's (land or ocean) surface. The ABL may show a large daily variation in wind, temperature, and stability or turbulence. The ABL is…

Wildland fires produce smoke that contributes to reduced visibility over roadways with potentially tragic consequences. Land managers need to reduce this potential hazard. Two indices are described that correlate with conditions associated with roadway hazard. The Dispersion…
