The Santa Ana winds were strong gusts of wind that brought dry air in from the Great Basin to Southern California each fall. These winds contributed to the conditions that created wildfires.

A portion of the article seen in the episode is a copy of sections from the online document "What Makes California So Susceptible to Wildfires?", which is available from the eco-friendly fashion shop Earthling. The relevant sections were "Fire Suppression" and "Santa Ana Winds". [1]
