What are the Santa Ana winds fueling the California wildfires?

Santa Ana: These winds are a big deal in Southern California, especially when it gets cooler. They’re known for making wildfires way worse. So, what’s the scoop on these winds?

Basically, Santa Ana winds are warm and dry gusts that blow from the desert towards the coast. They go against the usual flow of moist air from the Pacific. This means they can really dry things out, making it easier for fires to start.

These winds form when high pressure builds up over the Great Basin. As the air sinks, it loses moisture and heads towards Southern California. When it hits the mountains, it speeds up and gets even drier and warmer. Think of it like a river that gets faster as it goes through a narrow spot.

Now, why are they so bad for wildfires? Well, during these winds, humidity can drop to almost nothing. This makes plants super dry and ready to catch fire. Plus, the strong winds can turn a tiny spark into a huge blaze in no time.

Santa Ana winds have been behind some of the worst wildfires in the area, like the Woolsey fire in 2018, which was devastating. It destroyed over 1,600 buildings and took lives.

As for the name, it’s thought to come from Santa Ana Canyon in Orange County. Some folks even call them “devil winds” because of the chaos they can cause.
