How to create a tornado with known natural forces...
Take a 747 jumbo cargo plane to fly over a supercell thunderstorm, at 30,000 meters of altitude. Once in the middle of the supercell thunderstorm, drop one of those huge articulated passenger buses, being carried for this experiment, to pierce the cloud in its fall.
Predictions:
Subjected to gravity the free-falling object becomes a projectile accelerating at 9.8 m/sec per sec. with a trailing vacuum.
The atmospheric pressure, finds the path of least resistance towards the vacuum, creating a column of air that starts acting as a giant piston, pressing downwards. The air rushing top-to-bottom, is always the less dense air coming from above, as oppose to the denser humid air, inside the cloud.
The atmospheric pressure headed to reach 100,000 newtons per square meter combined with the coriolis force, start and maintain the rotation of the column of air at an increasing speed.
Once a strong vortex is established, it is the centrifugal force that maintains the vacuum that powers the system.
When the system reaches the bottom part of the supercell, it becomes visible in the form of a funnel. At touch-down, a tornado is formed. The tornado will continue for as long as the air rushing into the vortex continues to be of less density than the air in the surroundings, otherwise it dissipates.
