: Answer Unstable air = more active wildland fire behavior by increasing:
Likelihood of fire whirls and dust devils
Likelihood of gusty and erratic surface winds
The height and strength of convection and smoke columns
Likelihood of firebrands being lifted to great heights for long-range spotting Stable
air = less active wildland fire behavior by:
Limited rise of smoke columns
Reducing inflow of fresh air, limiting growth of wildland fire and their convective
column.
Lowering surface wind speeds and fire spread rates (except in mountainous terrains)
4. 6.4: Name 4 types of temperature inversions and describe their influence
on wildland fire behavior, including the thermal belt
