What Happens If Cold Air Meets Warm Air. when a warm air mass advances over a cold air mass, the warm air rises over, but at a gentler rate than a cold. as a cold front moves into an area, the heavier (more dense) cool air pushes under the lighter (less dense) warm air, causing it to rise up into the troposphere. when a warm air mass advances over a cold air mass, the warm air rises over, but at a gentler rate than a cold front. the presence of a cold front means that cold air is advancing and pushing underneath. in a warm front, a warm air mass moves into a cold air mass. The colder dense air forces warmer air higher into the atmosphere. Since the warm air does not rise as fast as a cold front, more stratus clouds form, and precipitation is not as heavy. cold fronts form when a cool air mass starts to displace warmer air in front of it. In a stationary front, neither air mass advances. the transition from cold air to warm air takes place over a long distance so the first signs of changing weather appear long before the front is actually over you. In a cold front, the opposite occurs.
