Wildfire requires three things to burn: an ignition source, fuel, and oxygen. If one of the three requirements is removed, the fire activity will be limited or nonexistent. Similarly, once a fire has started to burn, its behavior is determined by three factors: fuel (type, quantity, moisture level), topography (slope and aspect), and weather (wind, humidity, and temperature). The specific weather conditions during a fire event greatly influence how the fire burns. It follows that long-term climate variability can influence fire behavior by affecting site-specific fuel conditions (e.g., fuel moisture, type, and arrangement).
