Wildland fire behavior is affected by weather, fuel characteristics, and topography.. Weather influences fire through wind and moisture. Wind increases the fire spread in the wind direction, higher temperature makes the fire burn faster, while higher relative humidity, and precipitation (rain or snow) may slow it down or extinguish it altogether.
However, they are gaining popularity in modeling wildland fire emissions and in the development of fuel bed, fire hazard, and treatment effectiveness maps on several national forests. Unlike the Scott and Burgan Models which move away from the use of vegetation type as a proxy for fuel type, the FCCS relies heavily on vegetation type in the ...
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The computer program solves numerically a large eddy simulation form of the Navier–Stokes equations appropriate for low-speed, thermally-driven flow, with an emphasis on smoke and heat transport from fires, to describe the evolution of fire.
WRF-SFIRE is a coupled atmosphere-wildfire model, which combines the Weather Research and Forecasting Model (WRF) with a fire-spread model, implemented by the level-set method. A version from 2010 was released based on the WRF 3.2 as WRF-Fire .
Cal Fire currently has 14 Fire Hawks in its fleet, with the other two arriving in 2025. The newest helicopters are a heavy-duty complement to Cal Fire’s fleet of 34-year-old UH-1H Super Huey ...
The Forest Service raised the Wildland Fire Preparedness Level to Level 2 on Monday due to above-normal temperatures, increased wind and dry conditions. The Forest Service responded to 13 ...
This occurs when the fire's behavior is mostly controlled by winds generated by the fire's own plume. [9] This could lead to erratic conditions such as a column collapse and rapid runs. [10] Typical appearance of a plume-dominated fire. This picture was taken at the Silver Fire in Oregon in 1987. Typical appearance of a plume-dominated fire.
The LANDFIRE Program (“Landscape Fire and Resource Management Planning Tools") produces geo-spatial products and databases covering the United States. [1] [2] [3] LANDFIRE is a partnership between the wildland fire management programs of the United States Department of Interior, the USDA Forest Service and the Nature Conservancy. LANDFIRE was ...
