What happens when a hot air mass pushes into a cold air mass?

When a hot air mass pushes into a cold air mass, the warmer, less dense air rises over the cooler, denser air. This process can lead to the formation of clouds and precipitation, as the rising warm air cools and condenses. Additionally, the interaction between the two air masses can create instability, resulting in weather phenomena such as storms or fronts. This scenario is a key driver of various weather patterns.
