It is called a lower pressure front.
The region where a warm front and a cold front meet is called an occluded front. This occurs when a fast-moving cold front catches up to a slower-moving warm front, lifting the warm air mass off the ground. This creates a boundary where three air masses converge.
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.
Hurricane Sandy interacted with a cold 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.

lighting
Warm and cold air meet at a frontal boundary, such as a cold front or a warm front. When these air masses collide, it can lead to changes in weather patterns, including the development of storms and precipitation.
it when a cold front and a warm front meet
It is called a lower pressure front.
A stationary front occurs when a warm air mass and a cold air mass meet and do not advance due to similar air pressure. This can result in prolonged periods of clouds and precipitation along the front, creating unsettled weather conditions.
warm and cold air masses meet
The region where a warm front and a cold front meet is called an occluded front. This occurs when a fast-moving cold front catches up to a slower-moving warm front, lifting the warm air mass off the ground. This creates a boundary where three air masses converge.
as they collide the cold and warm front pushes the occluded front to become 3 air masses.
