Fire whirls are a rare but potentially catastrophic form of fire. These buoyant fire plumes are columns of ascending air with rotational motion which carry aloft smoke, debris, and flames greatly increasing the rate of fire spread .Fire whirls range from a foot or two in diameter to small tornadoes in size and intensity
Once a fire whirl leaves the influence of the main fire it quickly loses intensity and becomes an ordinary whirlwind
In order for a fire whirl to exist, there must be an organized source of angular momentum, either from wind shear or from the fire's convection column, which in turn creates large swirl velocities as air is entrained into the fire plume
Fire whirls occur most frequently where heavy concentrations of fuels are burning and a large amount of heat is being generated in a small area.
Mechanical forces are often present which serve as triggering mechanisms to start the whirl
.A common area for fire whirls is the lee side of a ridge where the heated air from the fire is sheltered from general winds. Mechanical eddies produced as the wind blows across the ridge can serve as the triggering mechanism to initiate the fire whirl. On flat terrain they tend to occur on the lee side of the fire near the outside edges of the front.
Even in small fires that aren't exhibiting extreme fire behavior, fire whirls can be created by lighting patterns. A rotational motion can be generated when two lines of fire come together, particularly if they approach at right angles. If large fire whirls are created, fire control problems can result.

What is the main difference between fire and respiration?
Aerobic respiration occur in living cells but fire does not occur in a cell. A fire activity occur in an open environment and does not require a material medium but aerobic respiration require a closed system which is usually the living cells to occur.
How can fire occur in the orange?

What whirls around the nucleus so quickly that they make a cloud of particles?
electrons
Where do volcanoes occur the most?
The most volcanoes occur around the Pacific Ocean, in an area called the Ring of Fire.
What is a firenado?
A firenado sounds like something from science fiction, like the cheesy Sharknado movie, but these are a real thing. Firenandoes are more properly known as fire whirls. They are most likely to occur in large fires, like a wildfire. The fire creates a whirlwind made of ash and flames, which then combine with the high winds that are caused by the extreme heat. The combination of the two creates eddies that spin like a tornado. The core of a firenado can reach up to 2,000 °F, and have winds of over 100 mph. These eddies can last over an hour, cannot be put out, and will set fire to anything in their path.
Is a fire devil a fire tornado?
Fire devils or fire whirls are sometimes referred to as fire tornadoes, but they are generally not considered true tornadoes.
How much time does a fire tornado last?
Fire whirls will usually last a few seconds to a few minutes.
What are fire tornadoes also called?
They are also called fire whirls. This is the term preferred by scientists as they technically are not tornadoes.
What are conditions for a fire tornado to occur in?
Fire tornadoes, more properly called fire whirls, generally form during very intense fires. Eddies, or weak vortices in the wind, may be caught in the rising air current or updraft of the fire. This causes the eddies to stretch, tighten, and intensify into fairly strong vortices, which then pull in smoke and fire.
What are fire tornadoes?
Fire tornadoes, also called fire whirls or fire devils are vorticies of smoke or flame that can form during very intense fires. These vorticies are technically not tornadoes.
Are fire tornadoes real?
Sort of but, they are called fire whirls but technically aren't tornadoes. They form in a way more like dust devils than real tornadoes.
Is there such thing as a fire tornado and can blow anything up?
There are fire whirls which are sometimes called fire tornadoes even though they technically are not tornadoes. They are whirlwinds made of smoke and/or fire. If they do contain actual fire they could potentially cause an explosion if they came in contact with something explosive just as the case is with any fire.
What is a whirling arm?
a arm that whirls
What are arches loops and whirls mean in crime investigation?
They are referring to types of finger prints, generally you either have whirls or arches and loops
What is close to rhyming wth worlds?
whirls
How does fire tornado work?
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.
Why does the ring of fire occur where it does?
Because it wants to occur (:
