Short summary
Wildfires pose serious risks to natural environments and cities, making it essential to predict how smoke travels through the air. We studied how wind patterns affect computer models of fire spread. We simulated fires under both smooth and turbulent airflows. Our results show that while assuming smooth wind is acceptable for light breezes, it causes errors in moderate winds. Therefore, models must account for natural turbulence to accurately predict fire plume in realistic weather.
