It is called a "cold front.
It is the leading edge of a cooler mass of air that is replacing a warmer mass of air at ground level.

If the cold air is advancing, that makes it a cold front.
No. The warm air mass always rises above the cold air mass. And if the cold air is advancing, that makes it a cold front.
The transition zone where a cold air mass is replacing a warmer air mass.
The boundary between a cold and warm air mass is called a front. One type of air will replace another as a front passes.
Fronts being the boundaries between two air masses - one warmer than the other - they are named for whichever air mass is advancing on the other. Cold air pushes in behind a cold front, and likewise a warm front has colder air retreating. If the boundary has stalled and neither air mass is pushing back the other, you have a stationary front.
a cold front.
Fronts in meteorology are the leading edges of air masses with different density.
If the cold air is advancing, that makes it a cold front.
No. The warm air mass always rises above the cold air mass. And if the cold air is advancing, that makes it a cold front.
A cold front is a zone where cold air mass is advancing to replace warmer air; usually moves west to east in North America. A warm front is a zone where warm air mass is advancing to replace cold air; usually moves more slowly then a cold air mass.
a cold front is a boundry of advancing mass of colled air a warm front is the oppposite its a mass of warm air
The transition zone where a cold air mass is replacing a warmer air mass.
Cold fronts are defined by cold air advancing, sliding under and displacing warmer air - they are steeper and move more quickly.Warm air cannot displace cold air easily because it is less dense. Therefore, it rides up and over it, producing stratus and nimbostratus clouds where light precipitation falls.the boundary of an advancing mass of warm air, in particular the leading edge of the warm sector of a low-pressure system.
The boundary between a cold and warm air mass is called a front. One type of air will replace another as a front passes.
The zone that separates two air masses when the denser and cooler mass is replacing the warmer mass as it advances describes the cold front. It is a boundary line that is between cold air and a warm air mass where the cold air pushes from under and behind as it advances.
When a cold air mass catches up to a warm air mass, it is called a cold front. At a cold front, the cold air replaces the warm air, creating a boundary between the two air masses. This can result in the formation of clouds, precipitation, and potentially severe weather.
Fronts being the boundaries between two air masses - one warmer than the other - they are named for whichever air mass is advancing on the other. Cold air pushes in behind a cold front, and likewise a warm front has colder air retreating. If the boundary has stalled and neither air mass is pushing back the other, you have a stationary front.
