When a mass of cold air collides with a mass of warm air, the warm air is lighter than the cold air, and it rises above it. This phenomenon is called convection, and it leads to the formation of clouds and precipitation. As the warm air rises, it cools down, and its water vapor condenses into droplets, which form clouds. If the clouds become large and dense enough, they can produce rain, snow, or hail. The boundary between the two air masses is called a front, and it can be stationary, moving slowly, or advancing rapidly. The type of front depends on the speed and direction of the air masses involved.
