The fire history that characterizes an ecosystem is its " fire regime ", which has 3 elements : ( 1 ) fire type and intensity ( e . g ., crown fires, severe surface fires, and light surface fires ), ( 2 ) size of typical fires of significance, and ( 3 ) frequency or return intervals for specific land units ( Heinselman 1981 ).

Of Cone's pitching with the Mets, Angell writes : " If you were a fan, what you began to appreciate in Cone was that his surface fire and exotic array of pitches _ the breaking stuff and the mid-90s fastball, the plummeting split-finger and the balls that flared crazily wide of the plate and ran up his counts _ concealed a steadfast, almost assembly-line regularity of output.

Many semi-empirical fire spread equations, as in those published by the USDA Forest Service, Forestry Canada, Nobel, Bary, and Gill, and Cheney, Gould, and Catchpole for Australasian fuel complexes have been developed for quick estimation of fundamental parameters of interest such as fire spread rate, flame length, and fireline intensity of surface fires at a point for specific fuel complexes, assuming a representative point-location wind and terrain slope.
