Stationary front
Air masses that are cold and forms over polar regions is polar. A cold front occurs when a cold air mass meets and displaces a warm air mass. A front that forms when a warm air mass is trapped between cold air masses and forced to rise is called a occluded front.

Tornado
The cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together.
Stationary front
If you mean when a mass of cold air meets a mass of warm air, then a front is created.

When dense,cold air meets less dense,warmer air, the warm air is pushed up
The cold air pushes under the warm air.
When dense,cold air meets less dense,warmer air, the warm air is pushed up
A warm front forms.
A warm front forms.
What happens is similar to when a warm air mass meets a cold air mass: the Cold Air Mass is forced to Subside beneath the Warm Air Mass. Thusly the warm air is uplifted, it cools and Rain is formed. When a Warm Air Mass meets a Cold Air Mass, the warm air is [again] forced to Rise above the Cold Air Mass, it cools and Rain is formed.

The point where these two air masses meet is called a front.If cold air advances and pushes away the warm air, it forms a cold front.When warm air advances, it rides up over the denser, cold air mass to form a warm front.If neither air mass advances, it forms a stationary front.
