Document Summary
The fire environment: fire weather: the fire environment triangle. Fire behavior is the manner in which fuels ignite, flames develop and fire spreads and exhibits other phenomena. It is a product of the fire environment. The fire environment triangle represents three environmental components, fuels, topography and weather, interacting with one another and with fire itself to determine the characteristics and behavior of fire at any given moment. They are also used to evaluate fire risk and hazard (e. g. , the canadian forest fire danger rating. System to be covered later in the course): weather. Weather is the condition of the atmosphere at a given place and time. Climate describes weather averages and variability for large areas and long time scales. Fire weather describes the elements that influence fire at the earth"s surface and troposphere. Fire season is the time of year during which fires are prone to burn, modulated by weather, generally april to.
