It depends. In the oversimplified scenario presented by the media, tornadoes form along a boundary between warm and cold air masses. However, tornadoes may also be caused by the boundary between masses of contrasting moisture content, rather than temperature. In other cases, they may form within a warm, moist air mass, away from any boundaries.

What kind of air masses are colliding over tornado alley?
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.
What type of air masses are involved with a typhoon?
Air masses are not involved in typhoons because these are tropical storms, as opposed to mid-latitude cyclones. The air in these storms is homogeneously tropical.
What type of front forms when a warm air mass is trapped by 2 cold air masses?
Stationary Front
How many air masses are involved in a stationary front?
Usually, a stationary front has two air masses. It becomes a stationary front when two different air masses are too weak to replace the other. A wide variety of weather can be found along a stationary front.
What are the origins of different tornado air masses?
Tornadoes in the United States are generally associated with collisions of air masses. In mmany cases there is a warm, moist air mass that originates over the Gulf of Mexico. This meets a cool air mass from Canada, a warm, dry air mass from the Rocky Mountains, or both.
What kind of air masses are colliding over tornado alley?
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.
When two air masses meet we normally refer to this as?
A Tornado A Front.
What type of air masses are involved with a typhoon?
Air masses are not involved in typhoons because these are tropical storms, as opposed to mid-latitude cyclones. The air in these storms is homogeneously tropical.
What do cool air masses do when they come in contact with warm air masses?
The cool air sinks, while the warm air rises. If it does so with enough force and torque, a tornado or hurricane will form.
Can a tornado form without a thunderstorm?
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.
What type of front forms when a warm air mass is trapped by 2 cold air masses?
Stationary Front
Why Does a tornado happen when air masses interact?
The tornado is not a direct result of the interacting air masses. When a warm and cold air mass collide the warm air, being less dense, is forced upward. If the warm air mass is unstable enough, this upward forcing triggers the formation of thunderstorms. If other conditions are right, these storms may go on to produce tornadoes.
How many air masses are involved in a front?
Usually two, but sometimes it can be three.
What is one reason so many tornadoes form in tornado alley?
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.
What kind of air masses bring tornadoes?
A tornado usually requires a warm, moist air mass, most often when it collides with a cool and/or dry air mass.
What weather would you get if a warm air mass runs into a cold one?
If the two air masses are moving together in different directions, you could get a tornado.
Air masses that form a tornado?
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.
