UNR scientists find causes of firenado in deadly Carr Fire
A destructive fire-generated vortex – a massive stream of rising, spinning, smoke, ash and fire – that topped out at 17,000 feet above the earth, accelerated the Carr Fire that killed eight people and devastated a widespread area in the Redding, California region in July 2018. The vortex, a little-observed atmospheric phenomena, was spinning with the power of a class three tornado, which earned it the name of Firenado.
Atmospheric scientist in the University of Nevada, Reno Department of Physics Neil Lareau has authored a paper in the scientific journal Geophysical Research Letters documenting the rare firenado, finding a number of factors that combined at just the right time and place to catalyze the deadly fire. These observations may help forecasters and scientists identify – and potentially warn – for future destructive fire-generated vortices.
