Large, high-intensity wildfires can generate their own extreme weather, including fire-generated thunderstorms (i.e., pyrocumulonimbus) and rare fire-tornados. My research aims to understand these phenomena using state-of-the-science radars and lidars, which can probe the internal dynamics of wildfire convective plumes. This talk will use these data to examine:
- Tornadic vortices generated during the Carr and Loyalton Fires
- Smaller, but still intense, vortices generated in both prescribed and wildland fire.
- The extreme updrafts occurring inside pyrocumulonimbus clouds.
Collectively these analyses help paint a clearer picture of how and when wildfires produce extreme weather, paving the way for nowcasting and warning for high-impact extreme fire behavior.
