Most often a warm, moist air mass collides with a cool air mass, a cold air mass, or both. However, such a collision alone will only form thunderstorms. Other factors are needed for those storms to produce tornadoes.
There are three different types of air masses.
Tornadoes cannot form in space. A tornado is a vortex of air. There is no air in space.
It forms air masses...
No!
Most tornadoes form in thunderstorms. When the cT and cP air masses meet they create instability in the atmosphere. As the cT air mass start to go up the cP air mass (basically the air) within the updraft tilts the circulating air from horizontal to vertical. The area of the rotation can be 2-6 miles wide and can extend through out the storm.
No, a tornado cannot form without a thunderstorm. A tornado needs the crossing winds of two air masses to provide rotation in order for a tornado to form. Tornadoes do not form from convection thunderstorms, but only from air mass thunderstorms.
The cool air sinks, while the warm air rises. If it does so with enough force and torque, a tornado or hurricane will form.
There are three different types of air masses.
Two types of air masses are cold and warm air masses. When they meet each other, a front forms.
The colliding air masses in Tornado Alley are warm, moist air from the Gulf of Mexico, cool air from Canada, and dry air from the Rockies. This collision is just part of the recipe for tornadoes.
It separates hot air masses and cold air masses
Tornadoes are a product of severe thunderstorms usually found where a warm, moist air mass collides with either a cooler air mass or a dry air mass.
Continental air masses form in the United States

In Tornado Alley Warm moist air from the Gulf of Mexico meets with dry air masses from the Rockies and/or cool air masses from Canada. These collisions can produce violent thunderstorms that can sometimes produce tornadoes. See the related question below for more detail.
