Fire whirls work in a manner somewhat similar to dust devils. The intense heat produced by a fire will always generate an updraft. As air flows into the fire it may gain some spin as it interacts with vegetation and topography. This spin can then be taken on by the updraft, producing a vortex of smoke and flames.
In some cases, yes. A fire tornado, more properly known as a firewhirl, may be steered by whatever winds are present.
It is loud because police and fire stations want everyone to be safe if a tornado warning in issued. It is basically a warning for people.
It is difficult to determine because, for understandable reasons, nobody has tried to measure them. Winds on a fire whirl can potentially exceed 100 miles per hour.
A tornado becomes a tornado when the circulation reaches the ground.
There is no definite starting point. Officially an EF0 tornado starts at 65 mph, but some have been rated with winds as low as 55 mph. However it is not wind speed alone that qualifies a tornado. Fire whirls, or whirlwinds spawned by fires, have had winds over 100 mph but don't count as tornadoes because they are not associated with thunderstorms and usually do not connect to cloud base. Dust devils, which form on hot, sunny days can, on rare occasions, have winds equivalent to an EF0 tornado, but for the same reason as fire whirls are not considered tornadoes.
a tornado in the form of fire
The "fire tornado" forms from the fire; it doesn't really matter how the fire starts. Also, a "fire tornado" is more properly called a fire whirl as it technically isn't a tornado.

A "fire tornado" is not a true tornado but a whirlwind spawned by an intense fire. If such a fire is approaching the area where you live you should evacuate immediately.
A "tornado" of fire is called a firewhirl, but these are not true tornadoes.
The fire tornado happened in Brazil august 25th of 2010
people will die if they touch the fire tornado. Alot of stuff will burn i saw it recently in russia,you know how distructive tornado is,imagine a fire tornado,he burn one 100 fields in very little time.
die
A normal tornado is a violently rotating column of air the descends from the rotating updraft of a thunderstorm. A fire tornado or firewhirl, which is technically not a tornado, is a vortex of smoke and/or flame that forms at ground level from the updraft of an intense fire. Firewhirls can potentially produce winds equivalent to an EF0 or EF1 tornado, but the main threat is their ability to spread a fire further.
A fire tornado's primary hazard is how fast it can spread fire. A fire tornado (more properly called a a firewhirl as it technically isn't a tornado) occurs when a massive fire, mostly a forest fire, slowly builds up heat. The warm air naturally goes upwards in a funnel shape, taking the flames with them. If you could imagine a fire tornado dancing above highly flammable treetops, you know the true dangers of them. They can spread a forest fire a lot quicker than normal.
When a tornado destroys a house it can rupture gas lines, which is a fire hazard. When a tornado takes down power lines it create sparks, another fire hazard.
In some cases, yes. A fire tornado, more properly known as a firewhirl, may be steered by whatever winds are present.
