Fire behaviour triangle

The fire behaviour triangle illustrates the key variables that affect how a wildfire behaves (Countryman 1966). Anything that burns is fuel, mainly live and dead vegetative material. Weather influences fire through the effects of wind, air temperature, precipitation, and relative humidity. Topography can directly influence the speed of fires and the type and condition of the fuel. Together, these variables determine the behaviour (speed, direction, and flame characteristics), and intensity of a fire.
