Which type of rainfall occurs when two air masses of different temperatures and other physical properties meet?

The type of rainfall that occurs when two air masses of different temperatures and other physical properties meet is cyclonic rainfall. When a warm air mass and a cold air mass meet, the warm air mass rises above the cold air mass, creating a low-pressure zone. As the warm air rises, it cools and condenses, leading to the formation of clouds and precipitation. This type of rainfall is called cyclonic rainfall because it is associated with the movement of cyclones and other low-pressure systems. Cyclonic rainfall is common in areas where air masses of different temperatures meet, such as along fronts, which are boundaries between air masses.
