Convection, wind, and gravity.
List three methods of mass transport of firebrands on wildland fires.
Smoke will continue to rise as long as it remains warmer than the
surrounding atmosphere.
Air parcels both rise and sink.
In an unstable atmosphere:
A convection column can lift firebrands above the fire, where the wind can
carry it ahead of the fire.
Describe how convection influences transport of firebrands.
Changes in fuel type, wind speed, and steepness of slope.
The primary factors that affect rate of spread are:

,A slope reversal from down to upslope, with a 6 mph wind blowing upslope
Which of the following changes would be expected to produce the largest
change in ROS?
Size and shape of fuels, compactness or arrangement of fuels, fuel
moisture, and fuel temperature.
The four fuel characteristics that affect the ignition of wildland fires are:
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.
Define fuel moisture content.

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.
Which one or more of the following statements are correct regarding wind-
driven and plume-dominated fires.
The stick method, a clinometer, and a GPS.
List three methods used in the field to determine slope percent.
North
Upslope winds typically weakest on what aspect?
Passive, active, and independent
The three stages of crown fire development include:
Fuels are preheated upslope through radiation and convection.
Rolling firebrands ignite new fuels below.
Slope affects fuel availability to burn because:

world. A fuel group is a grouping of fuel models that share similar
characteristics.
Describe the difference between Fuel Group and Fuel Model.
highest wind speeds on upper windward slopes
lowest wind speeds on downwind slopes
Which of the following topographic variations in wind speed would you
expect on a sunny summer afternoon?
Time of day, month of year, dry bulb temperature, relative humidity, aspect,
percent slope, shading of surface fuels.
Inputs used to determine fine dead fuel moisture content are:
Large-scale winds caused by the pressure gradients associated with highs
and lows.
General winds are:
