From whipping winds that fan flames to swirling smoke that obscures visibility, fire weather is a complex phenomenon. In Episode 4 of "Afire," hear from three meteorologists at the intersection of the intricate relationships between fire weather, wind, and smoke.

Brian Potter explains how large-scale atmospheric patterns, like extended dry periods before a wildfire, may contribute to the development of extreme fire events. Natalie Wagenbrenner discusses WindNinja, a high-resolution wind model that simulates local winds in complex terrain. And Scott Goodrick investigates the turbulent dynamics of small‑scale surface fires, as well as superfog—dense smoke-enhanced fog that can severely reduce visibility.
