Vortices born from intense fire-generated weather processes / From Wikipedia, the free encyclopedia
A fire tornado, sometimes also called a fire-generated tornadic vortex (FGTV) or a pyrotornado, is a vortex generated by a fire that reaches the scale and strength of a traditional tornado. Fire tornadoes are one of many kinds of vortices that appear in fires, varying in size...

Few confirmed examples exist, all of them occurring in the 21st century. The mechanism that leads to their formation are not entirely understood, but research suggests they have roots in both fire and cloud processes, making them distinct from both fire whirls (common in wildfires) and traditional tornadoes, which typically form via the mesocyclone of a supercell thunderstorm.
Pyro-tornadogenesis was first scientifically identified following a destructive vortex that formed during a bushfire on the outskirts of Canberra, Australia, in 2003. The vortex was filmed by multiple bystanders at a distance but was not generally accepted as a genuine fire-generated tornado until 2012. Several other examples have been recognized since.
