The typical, oversimplified scenario is often described as a cold air mass colliding with a warm air mass. However, this is not the direct cause of tornadoes. Such a collision often produces thunderstorms. Under the right circumstances these storms can produce tornadoes. Additionally, the warm-cold air collision isn't entirely necessary for tornadoes. Tornadic thunderstorms can form in a variety of circumstances.

Not directly. When a cold air mass plows into a warm air mass it produces a cold front. Thunderstorms can form along cold fronts. Given a few other conditions these thunderstorms can produce tornadoes.
There are no fronts "in" a tornado, though tornadoes are often associated with them. The tornado outbreak that affected Massacusetts on June 1, 2011 was associated with a cold front, which occurs when a cooler air mass pushes into a warmer one.
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.
No. A cold front is a boundary between two large-scale air masses where a cold air mass pushes into and displaces a warmer air mass. Thunderstorms often form along cold fronts, and these storms occasionally produce tornadoes.
When a cold air mass reaches a warm air mass, the warm air is forced to rise over the cold air due to its higher density. This interaction can lead to the formation of clouds, precipitation, and potentially severe weather such as thunderstorms.
A warm, moist air mass and a cold, dry air mass are most likely to form a tornado when they meet. The warm air rises rapidly, creating instability, while the cold air creates a temperature difference that enhances the development of severe thunderstorms and tornadoes.
Tornadoes typically form in a warm air mass, as that is what provides the energy, though it is often near a boundary with a cooler or drier air mass. However, due tot he pressure drop the air in a tornado is cooler than its surroundings.
Stationary Front
Cold air is not a necessary ingredient in forming tornadoes, but it often plays a role. One of the most common places to find a tornado is ahead of a cold front. A cold front is a boundary where a cool air mass pushes into and replaces a warmer one. Since warm air is less dense than cold air, the warm air mass gets force upwards. If there is enough instability in this air mass, the lift can trigger thunderstorms ahead of the front. Given the right conditions these thunderstorms can start rotating and produce tornadoes.
I don't know, but usually it creates a disaster like a tornado or a hurricane, so watch out for cold and warm are meeting.
A tornado is typically associated with a cold front, which is the leading edge of a cooler air mass pushing under a warmer air mass. The clash of cold and warm air can create the conditions necessary for the development of tornadoes.
