Which kind of precipitation occurs when a front or boundary line is formed between two air masses of contrasting temperature?

• A. Convectional
• B. Cyclonic
• C. Orographic
• D. Frontal

Answer: (D)

Frontal precipitation occurs when a front or boundary line is formed between two air masses of contrasting temperature. Along the fronts, the warm air rises above the denser cold air. The mid-latitude regions experiencing the convergence of warm tropical and cold polar air masses are important areas receiving frontal precipitation.
