List three methods of mass transport of firebrands on wildland fires.
Convection, wind, and gravity.
In an unstable atmosphere:
Smoke will continue to rise as long as it remains warmer than the surrounding
atmosphere.
Air parcels both rise and sink.
Describe how convection influences transport of firebrands.
A convection column can lift firebrands above the fire, where the wind can carry it
ahead of the fire.
The primary factors that affect rate of spread are:
Changes in fuel type, wind speed, and steepness of slope.
Which of the following changes would be expected to produce the largest
change in ROS?
, 2|Page
A slope reversal from down to upslope, with a 6 mph wind blowing upslope
The four fuel characteristics that affect the ignition of wildland fires are:
Size and shape of fuels, compactness or arrangement of fuels, fuel moisture, and
fuel temperature.
Define fuel moisture content.
Fuel moisture content is the amount of water in a fuel, expressed as a percent of the
oven-dry weight of that fuel. (Wet-weight (-) Dry-weight) / Dry-weight = Fuel
moisture percent.
The Fire Weather Planning Forecasts, Spot Forecasts, Red Flag Warnings, and
Smoke Management Forecasts are products issued by:
The National Weather Service
Which one or more of the following statements are correct regarding wind-driven
and plume-dominated fires.
Wind driven fires are easier to predict the direction of spread.
Plume dominated fires have similar hazards to thunderstorms.
In plume dominated fire, the convective column dictates the fire activity.
List three methods used in the field to determine slope percent.
