Which cloud type is associated with strong erratic updrafts and downdrafts that influence fire behavior?

• A. Lenticular
• B. Mares tail
• C. Cumulonimbus
• D. Cirrus

Answer: (C)

Cumulonimbus clouds drive strong, turbulent convection with powerful updrafts and downdrafts, which can dramatically alter wildfire behavior. These storms produce gust fronts and microbursts that shove wind around the fire, causing rapid changes in spread rate, direction, and spotting potential. The other clouds are either high and wispy or smooth and stable, not associated with the violent vertical motions that drive erratic fire behavior.
