No, a warm front is not created when two air masses meet and neither one moves.

Here's why:

* Warm fronts form when a warm air mass moves into and displaces a colder air mass. The warm air is less dense than the cold air, so it rises over the cold air, creating a sloping boundary called a frontal zone.

* The movement of the air masses is essential. If neither air mass moves, they would simply mix and create a new air mass with characteristics somewhere between the two original ones.

In summary, a warm front requires the movement of a warm air mass into a colder air mass for its formation.
