1) Rate of temperature change with elevation determined by the vertical distribution of temperature at a given time and place.


2) Increase of temperature with height in the atmosphere. Vertical motion in the atmosphere is inhibited allowing for smoke buildup. A "normal" atmosphere has temperature decreasing with height.


3) Natural or artificial topographic incline; degree of deviation from horizontal.


4) Most active part of a wildland fire; OR the forward advancing part.


5) (1) Property that may be endangered by a fire burning in another structure or by a wildland fire. (2) Direction in which a slope faces. (3) General surroundings of a site with special reference to its openness to winds and sunshine.


6) Area of unburned fuels, not necessarily green in color, adjacent to but not involved in a wildland fire.


7) Force exerted by the weight of the atmosphere per unit area.


8) Partly decomposed and matted leaves, twigs, and bark beneath the litter of freshly fallen twigs, needles, and leaves.


9) (1) Individual incendiary fire. (2) Point or points of origin of an incendiary fire. (3) Material left to ignite an incendiary fire at a later time. (4) Individual lightning or railroad fires, especially when several are started within a short time. (5) Burning material at the points deliberately ignited for backfiring, slash burning, prescribed burning, and other purposes.


10) Behavior of a fire producing sparks or embers that are carried by the wind to start new fires beyond the main fire.


11) Massive natural cover fuels such as logs, snags, and large limbs. Heavy fuels are not easy to ignite; once ignited, they burn slowly and hot.


12) Meteorological instrument used to determine relative humidity.


13) Manner in which a fire reacts to the variables of fuel, weather, and topography.


14) Collective term that refers to stands of vegetation dominated by shrubby, woody plants or low-growing trees, usually of a type undesirable for livestock or timber management.


15) Factors that make up fuels such as compactness, loading, horizontal continuity, vertical arrangement, chemical content, size and shape, and moisture content.


16) Highly trained fire fighting crew used primarily in handline construction.


17) Percentage of moisture in the air compared to the maximum amount of moisture that air will hold at that temperature.


18) Facilities in which there is a great potential likelihood of life or property loss.


19) Simulated fuel complex for which all fuel descriptors required for the solution of a mathematical rate-of-spread model have been specified.


20) Leading edge of a relatively cold air mass that displaces and may cause warmer air to rise. If the lifted air contains enough moisture, cloudiness, precipitation, and even thunderstorms may result.
