What happens to the air masses at a stationary front?

At a stationary front, the air masses involved remain in place without significant horizontal movement. This occurs when a cold air mass and a warm air mass meet but neither is strong enough to push the other out of the way, leading to a stalemate. The result is that the characteristics of both air masses can persist for extended periods, leading to prolonged weather conditions that are typically stable.

While stationary fronts can lead to some gradual changes over time, such as the potential for cloud formation and precipitation, significant and rapid weather changes are not typical. This stability can lead to persistent cloudiness and light rain or drizzle. Therefore, the behavior of the air masses at a stationary front aligns with the idea that they remain separate and do not actively move against each other.
