There can be a few explanations for this. Most tornadoes start developing a few miles above the ground and descend from the clouds to make contact for the ground. This usually results in a visibly descending funnel cloud. However, if the air under the parent storm is dry, the funnel, which is formed from condensed moisture, may not form. In such a case, the developing tornado may be invisible until it reaches the ground and starts lifting dust, giving the ppearance that it is forming upwards.
Another potetial case of this is with landspouts. These are relatively weak tornadoes that develop without a larger mesocyclone. Landspouts form as low-level rotation in the atmosphere gets caught in the updraft of a thunderstorm and is stretched and intensified into a tornado.
Some data from Doppler radar suggests that some tornadoes in supercells form from the ground up rather than the clouds down as conventional thinking goes. Scientists are still unsure of how this happens.

What happens after a tornado picks up dirt?
After a tornado picks up dirt, the dirt particles are carried along with the tornado's swirling winds. As the tornado moves, it can deposit the dirt particles when its winds weaken or when it dissolves. The dirt can then settle back to the ground once the tornado dissipates.
What does a tornado do to make dust?
Tornadoes can pick up dust and debris from the ground as they travel, creating a dusty appearance. The strong winds within a tornado can lift dirt particles into the air, making them visible as swirling dust clouds.
What happens if a tornado strikes the ground?
When a tornado strikes the ground, it can cause significant damage by tearing apart structures, uprooting trees, and tossing debris at high speeds. Tornadoes can create a path of destruction that is several miles long and can be up to a mile wide. It is important to take shelter immediately in a sturdy building or underground if a tornado is approaching.
What are the five stages of tornado?
The five stages of a tornado are 1. the whirl stage--when the cumulonimbus clouds begins being hit by winds blowing in different altitudes, and start rotating horizontally. this causes a funnel of air to form, otherwise known as a vortex, both whirling around and up. 2. the organizing stage--once the funnel touches the ground, it forms a solid base, and the upward, whirling motion sucks up debris into the funnel. this causes the tornado to darken. 3. the mature stage--this is the most destructive stage, where things are destroyed, as it is the most powerful. 4. the shrinking stage--when the tornado is dissipating, and weakens to the point where it is no longer visible, and slowly begins to die down. 5. the decaying stage--the tornado is completely gone.
How does a tornado pick up objects?
Well, isn't that a fascinating question! You see, a tornado picks up objects by creating a swirling vortex of air that moves very quickly. As the tornado spins, it creates a low pressure area that can lift objects off the ground. It's like nature's own gentle dance, swirling and twirling with the world around it.
Does a tornado start from the ground or the sky?
Tornadoes typically start from the cloud base and extend downwards towards the ground. The rotating column of air becomes visible as it picks up debris and dust from the ground, giving the appearance of a funnel shape.
Does a tornado form on the ground first?
No. General scientific consensus is that most tornadoes start forming up inside a thunderstorm and extend downward. There is evidence that some tornadoes form from the ground up, however.
How wide can a tornado be at ground?
Scientists believe that in extreme cases a tornado can get up to about 2.5 miles wide
Do tornadoes start at the bottom?
No, Tornadoes start inside the clouds of their parent thunderstorms and descend towards the ground. Somtimes they can appear to form up from the ground because the vortex is just swirling air when it reaches thr ground and therefore cannot be seen until it starts picking up dust from the ground.
Does a tornado from bottom to top?
Air moves up in a tornado, but in the process of forming, most tornadoes start as a vortex high up in the clouds.
What happens after a tornado picks up dirt?
After a tornado picks up dirt, the dirt particles are carried along with the tornado's swirling winds. As the tornado moves, it can deposit the dirt particles when its winds weaken or when it dissolves. The dirt can then settle back to the ground once the tornado dissipates.
What does a tornado do to make dust?
Tornadoes can pick up dust and debris from the ground as they travel, creating a dusty appearance. The strong winds within a tornado can lift dirt particles into the air, making them visible as swirling dust clouds.
What is tornado made of?
A tornado is made up of rapidly rotating air that extends from a thunderstorm to the ground. The rotation is typically caused by wind shear within the storm system. Tornadoes can also contain debris and dust picked up from the ground as they move.
Which is the first thing that happens when a tornado forms?
When a tornado forms, violent rotating winds reach ground level, often kicking up a cloud of dust in the process.
Can a tornado cause damage without touching the ground?
Yes and no. The funnel of a tornado does not have to reach the ground for damaging winds to occur at ground level. However, if those winds reach the ground then the tornado has touched down even if the funnel hasn't.
What happens to the stuff a tornado picks up after it dies?
After a tornado weakens and dissipates, the debris it picked up can fall back to the ground or be carried away by the wind. Items may be dropped back relatively close to where they were originally picked up or scattered over a wider area depending on the strength of the tornado.
What happens if a tornado strikes the ground?
When a tornado strikes the ground, it can cause significant damage by tearing apart structures, uprooting trees, and tossing debris at high speeds. Tornadoes can create a path of destruction that is several miles long and can be up to a mile wide. It is important to take shelter immediately in a sturdy building or underground if a tornado is approaching.
