|
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.
