It depends. Some sources list four stages while other's list five. The differences concerns the later stages.If four stages are listed they are typically "dust whirl stage" "organizing stage" "mature stage" and "rope out stage"
However, some sources divide the rope out stage into a shrinking stage and a rope stage.
Most tornadoes narrow as they lose power in what some call the rope stage. However, the five step model makes note that it is typically in the final parts of the narrowing that the true rope stage takes place as the structure of the tornado breaks down.
However, not all tornadoes go through these exact stages. Some never make it past the dust whirl stage, while others never rope out, but gradually widen until dissipating.
Tornadoes often go through a series of stages as they develop, strengthen, and dissipate, often with distinct appearances.The dust whirl stage: The ground-level circulation of the tornado is developingThe organizing stage: The tornado is on the ground and increasing in size and intensity.The mature stage: The tornado is at its largest and generally strongest point.The shrinking stage: The tornado begins to narrow and lose energy. Due to dynamic effects, some tornadoes intensify at this point.The rope-out stage: The tornado becomes very narrow and the funnel may bend and wind as the tornado weakens and eventually dissipates.
The steps of tornado formation are:Dust whirl stage: This is when the vortex has first made contact with the found and has started lifting dust, leaves, or similar material.Organizing stage: The tornado, having become established grows and intensifies.Mature stage: The tornado is at its largest point and is usually at peak intensity.Shrinking stage: The tornado begins to grow narrower and generally weaker, though some tornadoes briefly intensify at this point.Rope-out stage: The vortex is decaying rapidly and the funnel often takes on a winding rope-like appearance. It will dissipate fairly soon.
In the first stage of tornado prediction scientists look for general weather conditions. The conditions include wind shear and systems that can form strong thunderstorms such as a cold front, dry line, or low pressure system.If such general conditions are in place a tornado watchis issued.The second stage scientists look for conditions that may soon produce a tornado, or if a tornado is forming. These include using Doppler radar to look for strong rotation in thunderstorms or possibly even the signature of an actual tornado. Storm spotter are also sent out to report strong rotation, funnel clouds, and tornadoes. If strong enough rotation is detected or if an actual tornado or funnel cloud is spotted or detected a tornado warning is issued.
No, a haboob is not a tornado.
With a death toll of 158 the Joplin tornado of May 22, 2011 was the seventh deadliest tornado in US history, the deadliest in the US since 1947, and the first single tornado to kill more than 100 people since 1953.The damage cost of $2.8 billion marks it as the costliest tornado in U.S. history even with adjustment for inflation.It was the fifth of six tornadoes in 2011 to be rated EF5, tying the annual record set back in 1974.From its formation the Joplin tornado has multiple smaller vortices inside its funnel, which added to the destruction.The tornado formed only a mile outside of Joplin and intensified very rapidly, leaving little time to alert people that a tornado had formed.a number of odd phenomena were observed after the tornado, including a chair with its legs stuck in a wall, a hose stuck through a tree trunk, and a wooden been impaled through a concrete curb.
The five stages a tornado goes through are: The dust whirl stage, when the circulation first touches the ground The organizing stage, in which the tornado grows and intensifies The mature stage. when the tornado is at its largest and typically strongest The shrinking stage in which the tornado begins to lose strength The rope out stage in which the vortex decays and finally dissipates, often twisting and bending as it does so. Of these stages the mature stage is usually the most destructive.
The Fifth Stage was created on 2009-11-30.
The 4 stages are:The organizing stage where the tornado touches down and intensifies.The mature state when the tornado is at its largest and usually its strongest.The shrinking stage in which a tornado begins to lose energy.The rope stage where a tornado starts to break up.

There are five stages to which a tornado typically goes through through. Tornadoes are formed during the mature stage of a supercell under the right conditions. The first stage of a tornadoes life cycle is called the "Dust Whirl stage." This stage occurs when a wall cloud or any other type of rotation above, whips up dirt, dust, leaves, grass, etc. The second stage is called the "Organization stage." This stage is important to the tornado's life cycle because it is able to improve the structure, hence increasing wind speed and velocity, and volume. The third stage of a tornado's life cycle is called the "Mature stage." This stage is when the tornado has typically reached it's greatest, strength, size, wind speed, and maturity. The forth stage is called the "Disipating stage." During this stage, the tornado begins to weaken, shrink, and lose its structure. Though in some cases tornadoes may intensify as they shrink The Final stage of the tornado's life cycle is called the "Rope stage." The rope stage happens when the tornado literally has little TO NO STRUCTURE AT ALL. The tornado twists and turns, bends and winds, in all types of shapes and directions.However, this is concept is somewhat idealized. Not all tornadoes go through these five stages as described.
The Fifth Stage of Labor - 2013 was released on: USA: 15 July 2013
The steps of tornado formation are:Dust whirl stage: This is when the vortex has first made contact with the found and has started lifting dust, leaves, or similar material.Organizing stage: The tornado, having become established grows and intensifies.Mature stage: The tornado is at its largest point and is usually at peak intensity.Shrinking stage: The tornado begins to grow narrower and generally weaker, though some tornadoes briefly intensify at this point.Rope-out stage: The vortex is decaying rapidly and the funnel often takes on a winding rope-like appearance. It will dissipate fairly soon.

Depending on how many steps it is broken down into, the second stage may either be the growth stage or the mature stage.

Tornadoes cannot collapse in on themselves. In many cases a tornado will become much narrower as it enters its dissipating stage, and is said to be "roping out." During this stage the winds in the tornado may actually speed up as angular momentum is conserved. It is still considered a tornado until it dissipates completely.
