Ch 3: Fire Weather Principles | Fire In California's Ecosystems

The fire behavior triangle consists of fuel, weather, and topography, with weather being the most dynamic element due to the impact that sudden changes in temperature, moisture, wind, and stability can have on wildfire.
Warmer temperatures bring fuels closer to their ignition point, but the main role of temperature is in how it influences the other components.
For example, warmer air can hold more moisture, so as temperature goes up, relative humidity goes down. Drier air pulls more moisture out of the fuels, making it easier for fires to start and spread.
Additionally, differences in temperature across an area are the primary cause of wind, which has major impacts on fire behavior. Wind supplies more oxygen to the fire, transports heat, and can even toss burning embers ahead of the major blaze to create spot fires.
Stability can be a bit harder to grasp, but think of it like a chimney. An unstable atmosphere is like having the damper open. With more airflow, the fire becomes more active.

Most Excellent Holt... 👍🏻👍🏻👍🏻

I’ve always wondered if the intensity of brush fires 🔥 increase the likelihood of a wetter than normal Winter. One day I’ll have to figure out how to research that phenomenon as it has stuck with me for a long time. Do you know? Thank you for the informative videos 😊
