Fire Behavior and Spread Interpretation

Mother Nature has apparently upgraded her resume to include "performance artist specializing in colossal, wind-driven conflagrations," as evidenced by fires leaping across continents with the agility of an Olympic long-jumper, torching entire neighborhoods with a casual shower of embers, and even generating their own apocalyptic weather systems, all while casually doubling in speed and intensity whenever the landscape gets a little too dry or we neglect the preventative housekeeping of prescribed burns.
