A video capturing a whirling vortex of smoke during the Park Fire in California has sparked curiosity among scientists who are investigating whether it was a rare fire tornado or an example of extreme fire behavior. The rotating column of smoke resembled a tornado, leading experts to consider the possibility of a fire tornado hidden within. The video shows two rotating vortices, indicative of strong updrafts found in fires that produce fire tornadoes. The Park Fire, fueled by record-breaking temperatures and dry vegetation, has rapidly spread to over 348,000 acres within days of ignition.
Fire tornadoes, also known as fire-generated tornadic vortexes or pyrotornadoes, are large vortexes with strong winds created when an intense wildfire’s plume of smoke interacts with the heat below and the surrounding environment. While fire whirls, smaller rotating tendrils of flames or smoke, are common along fire edges, fire tornadoes are more intense and rare. The increasing occurrence of these events is uncertain, but recent studies suggest fires are intensifying, potentially leading to more exotic phenomena like fire tornadoes.
Confirmation of a fire tornado typically involves surveying wind damage, although no reports have been received so far in the case of the Park Fire. Firefighters at the scene may have witnessed the event, but with their focus on battling the blaze, confirmation remains elusive. Regardless, the proliferation of live cameras, such as the one capturing the Park Fire, provides researchers with valuable insights into wildfire behavior and the occurrence of rare events like fire tornadoes.
