Why doesn't a tornado happen when just cold air meets or hot air meets?

Because warm and cold air alone won't produce the rotation needed for a tornado. First, the warm air mass must be moist so that when the collision occurs thunderstorms form.
Second, the speed and/or direction of the wind must vary with altitude in what is called wind shear. This tilts thunderstorms, separating the updraft from the downdraft and thus allowing them to become stronger last last longer.
Second, the wind shear creates rolling air masses that can start the thunderstorms rotating.
Under the right conditions a tornado can develop from this rotation. How exactly this happens is not fully understood.

Where do tornadoes happen the most and why?
Tornadoes happen most in the United States in a place called 'Tornado Alley'. They mostly happen there because of the air. Tornado Alley is in the middle of the United States. So cold air from higher up in the world comes down and meets hot, humid air from down lower by the Equator. That hot air comes up and that's how the two airs meet. Then they form tornadoes.
Can snow occur during a tornado?
No. Tornadoes are often accompanied by rain or hail, but if it is cold enough for snow, it is too cold for a tornado.
What happens when a cool air mass meets and replaces a warm air mass?
Depending on how they collide, it can result in a tornado. But if it were to just simply replace the warm air mass, it would just be a cold front.
Are tornadoes usually formed in tornado ally?
Yes the majority of tornadoes happen in tornado alley. However it is not because tornado alley is generally flatter then the rest of the US. It has to do with the warm air from the Gulf of Mexico meeting the cold air from Canada in that region that causes tornadoes to mainly form there.
Where do Precipitation and storms occur in?
Does precipitation and storms occur in high pressure sytems Precipitation and storms occur when cold air meets hot air. This can also happen when a cold front moves into a warmer area.
What is it called when cold air meets warm air?
tornado
Warm moist air meets cold dry air over land?

Which of the following air results when warm moist meets cold dry air over land?

What happens when rapidly falling cold air meets rapidly rising hot air?
A tornado forms

What happen when cold air meets hot air?
well it usually makes a thunder Storm
Can a tornado happen in antarctica?
No. It is too cold in Antarctica for tornadoes.
What would happen when cold water from the Antarctic meets warm water from the equator?
A giant nuclear explosion would happen and we would all die.
When can a tornado happen?
A tornado can happen when the wind spins in a circle, wind spins around near and during a thunderstorm, and when hot and cold air meet. Most tornadoes happen May - August, summer for most people. But be aware, tornadoes can happen any time, anywhere, and in any thunderstorm or hurricane
What 2 fronts can cause a tornado?
cold and warm fronts can cause a tornado
