This activity is called elevation.
This phenomena takes place in the south east quadrant of The Low Pressure System and is known as and called The Warm Front.
Cold air masses subside underneath warm air masses in the south west quadrant of The Low Pressure System and this is known as and called The Cold Front.
When air rises it cools and moisture condenses into raindrops; this explains the Rain that is constant at both Fronts.
The front you are referring to is called a cold front. Cold air is denser than warm air, so when a mass of cold air moves underneath warm, moist air, it lifts the warm air rapidly, leading to the formation of clouds and potentially precipitation.
When a warm air mass moves into an area where a cold air mass is located, it is called a warm front. At a warm front, the warm air mass rises over the cold air mass, leading to gradual temperature increases and cloud formation.
It would be a cold-front
The contact zone is called a cold front.
