Fire intensity. n. The amount of energy or heat release per unit time. FireWords uses a non-specific definition of fire intensity that encompasses several specific types of fire intensity measures.
Byram (1959) defined the term as the rate of energy or heat release per unit time, per unit length of fire front, regardless of its depth. However, to avoid confusion with related terms, we suggest the specific term fireline intensity when referring to Byrams definition.
