What are the characteristics of a warm front occlusion?

A warm front occlusion typically occurs when a warm front meets a cold front, and is characterized by the lifting of warm air as the colder air mass pushes underneath it. When evaluating the characteristics of a warm front occlusion, one of the key elements is that the warm air behind the occlusion is actually warmer than the air that is ahead of it.

In this situation, the warm air mass, when it rises, results in a gradual transition and can lead to the formation of clouds and precipitation. Understanding this characteristic is crucial for forecasting weather changes associated with warm front occlusions, as they can influence local weather patterns significantly.

The details associated with other options provide considerations for different atmospheric conditions, but they do not accurately describe the nature of a warm front occlusion itself. Focusing on the fact that the air behind the occlusion is warmer than what is ahead highlights the unique aspect of this weather phenomenon, further accentuating its role in meteorological patterns.
