# The soot field's fresh-breeze lane (the FIRE_FIXTURE driver): 8 m/s
# FROM 25 - past the envelope's sheltering limit, so the plume lays
# over hard: the column above the fire thins to a thread, the aloft
# mass exits downwind, and the total saturates low (the wind is the
# field's exit). Ends before the downwind orb ignites.
# weather: wind 8 25
