an occluded front?
It is called a lower pressure front.
front
It depends on which air mass replaces which in the area. If a cold air mass advances and pushes a warm air mass away, the result is a cold front. When a cold air mass retreats and is replaced by a warm air mass, the result is a warm front. When the two air masses meet and neither advances, the result is a stationary front.
A cold front is created because of density. When air warms up, the molecules that make up the air move faster, causing them to spread out further. This makes the air less dense than the cold air, whose molecules are closer together, making it more dense. Because of this, when the two walls of air meet, the cold air cuts underneath the warm air, forcing it upwards, making it cold on the ground.
A stationary front
They meet at a front.
An Occluded front.

an occluded front?
It is called a lower pressure front.
warm and cold air masses meet
as they collide the cold and warm front pushes the occluded front to become 3 air masses.
