Doppler radar can be used to make such predictions.
Doppler radar.
Doppler radar is used to track potentially tornadic storms.
Only to a limited degree. Doppler radar can detect a mesocyclone, which is a rotating updraft in a thunderstorm that can produce a tornado. Radar can also detect the much smaller signature of a possible tornado, though this can be difficult, especially for weak and short lived tornadoes. Even if radar detects such a signature, it cannot tell if it is on the ground of if it will touch down, but it is enough to prompt a tornado warning. By detecting where a mesocyclone or possible tornado is and knowing the direction of the storm, it is possible to see what areas might be in damager. Even with this technology some tornadoes strike without warning, and there are many false alarms.
To a limited degree. It is possible to detedct a tornado and its immediate precursors with Doppler radar, but this cannot tell when the tornado will touch down, how long it will last, or if it will change course. Beyond this, weather conditions can tell if a given areas is at risk from tornadoes on a given day, but cannot tell where indivitdual tornadoes will strike.
Only to a very limited degree. Scientists can determine when conditions are favorable for tornadoes to develop (in which case a tornado watch is issued), or even if a tornado may be developing (which would prompt a tornado warning), but cannot predict exactly where or when a tornado will touch down.
When you touch the touch screen little shiny dots might on the walls of the underground walk over to it and click "a".
A tornado that does not touch the ground is a funnel cloud.
Yes
A tornado is not a solid thing that you can touch, it is a vortex of very fast wind.
Yes
It depends what you call a tornado. Most tornado-like clouds do not touch the earth's surface. Some say that until it touches the ground it is not a tornado but a funnel cloud; however the definition of a tornado does not state that it must touch the ground. It all depends on what you're taught.
