Which atmospheric condition causes a temperature inversion and what effect does it have on wildland fire behavior?
-
A
Warm air trapped beneath a layer of cooler air, suppressing smoke and reducing fire spread
-
B
A layer of warm air above cooler surface air, which traps smoke and limits vertical mixing
-
C
Cool air aloft pushing down on warm surface air, increasing wind speed at ground level
-
D
Equal temperature at all altitudes, promoting uniform fire spread in all directions
