TORNADO
1. Can create fire tornadoes?
A scale of fire in the movie is too small to create a fire tornado.
In the Movie
A fire tornado caused when a tornado sucked the flames into its vortex.
In facts
Fire tornadoes, also called fire whirls or fire devils, are rare. But they form in the same basic way as ordinary dust devils. If a small patch of hot air rises quickly enough through the cooler air above and around it, it can become a rotating column of air which picks up dust and small debris. In a fire tornado, the fire itself heats the rising air, and the vortex carries flaming material aloft. Those are typically caused by high winds during large forest fires, rather than a situation like the one in the film.
But, idea is not impossible. If a tornado gets rapidly rotating columns of air that can pull up the flames, you can see the fire tornado.
