In terms of weather a tornado is a very fast process.
Once formation starts, a tornado usually takes just a few minutes to a few seconds to touch down. A typical tornado will be into and out of a given spot after just a few seconds. A large or slow moving tornado may take a minute or more.
its when something is slowing down
The air in a tornado spirals upwards.
A tornado wrecks things and sometimes tears down houses.
In terms of weather a tornado is a very fast process.
A tornado follows a relatively narrow path that is usually fairly straight but can meander somewhat. Slow-moving tornadoes may have erratic, looping paths.

A satellite tornado is a tornado that touches down near and usually orbits a larger tornado within the same mesocyclone.
10 to 20 mph would be a slow moving tornado. A typical tornado travels at 30-35 mph.
I think you mean slow down and speed up. slow down =slow, speed up=fast
The process of a tornado forming is called tornado genesis. Usually a tornado is a funnel cloud before it touches down.
When a tornado first reaches the ground and becomes a tornado it is said to have touched down.
The air in a tornado spirals upwards.
A tornado wrecks things and sometimes tears down houses.
A slow-moving tornado tornado might travel at 10 mph, but a vortex with 10 mph winds would by no means be considered a tornado. The winds must be strong enough to produce damage.
