when warm air meets cool air and either one don't move its called a stationary front
A front forms. The type of front depends on which air mass is advancing. If the cool air mass advances, it is a cold front. If a warm air mass advances, it is a warm front. If neither advances, it is a stationary front.

An air mass that forms over Canada is typically classified as a continental polar (cP) air mass. This type of air mass is characterized by cool, dry conditions due to its formation over land in the northern latitudes. It can bring chilly temperatures and clear skies to regions it moves into, especially during the winter months. If the air mass travels southward, it may influence weather patterns in the United States.

occluded
A stationary front occurs when a warm air mass and a cold air mass meet but remain in place, leading to prolonged periods of rain or other forms of precipitation.

Intrusive
When a warm air mass and a cold air mass meet without being able to displace each other, a stationary front forms. This results in stable weather conditions, with clouds and precipitation often extending over a large area.
