Causes and Behavior of Wildfires: A Comprehensive Overview
TLDR Wildfires can be caused by human activity or natural factors, with fuel, weather, and topography playing key roles in determining how a fire will spread. Elite firefighters, such as hot shots and smoke jumpers, work to build fire breaks and stop fires, but sometimes fires can still become uncontrollable.
Timestamped Summary
00:00
A wildfire in Arizona in 2002 was started intentionally by a firefighter and a woman who wanted to get the attention of a news helicopter.

The three main factors that determine what will happen with a forest fire are fuel, weather, and topography, with fuel referring to the amount and type of fuel available for the fire to burn.
12:51
The second factor that determines how a wildfire will spread is weather, particularly wind, which can push the fire in unpredictable directions and create its own weather system.
16:31
Fire can create its own wind and move in unpredictable directions, and temperature also plays a role in wildfire behavior.
20:14
Topography plays a role in wildfire behavior, with fires typically spreading faster uphill, but there are cases where fires can burn down sloped mountains, which is unusual.
23:53
Hot shots and smoke jumpers are elite firefighters who work in teams to build fire breaks and stop fires from spreading, but sometimes fires can still leap over fire breaks and become uncontrollable.
