Which front occurs when a cold front overtakes a warm front?

• A. Cold Front
• B. Warm Front
• C. Occluded Front
• D. Stationary Front

Answer: (C)

An occluded front occurs when a cold front overtakes a warm front. This situation develops when the faster-moving cold air mass catches up to the slower-moving warm air mass, forcing the warm air to be lifted off the ground. The lifting of the warm air can lead to cloud formation and various types of precipitation, often causing complex weather patterns.

In an occluded front, the cold air effectively pushes the warm air aloft, and as a result, the characteristics of a cold front and a warm front merge in this zone. The merging of these air masses can lead to significant changes in weather, including the potential for storms and precipitation. Understanding this dynamic is crucial for predicting weather patterns that occur during such frontal interactions.
