In terms of movement, how does an occluded front behave?

An occluded front occurs when a fast-moving cold front catches up to and overtakes a warm front. This process typically happens in mid-latitude cyclones, where the dynamics of conflicting air masses—cold, warm, and sometimes cool—interact. As the cold front advances more rapidly, it rises over the warm air mass. The result of this interaction is the occlusion of the warm air mass, effectively lifting it off the ground as the cold air masses collide.

This behavior of occluded fronts is significant in meteorology because it signifies the later stages of a storm system's life cycle and can often lead to significant precipitation as the warm air is forced to rise, cool, and condense. By understanding this movement, meteorologists can predict weather changes associated with occluded fronts more effectively.

The other options do not accurately describe the dynamics of an occluded front. For instance, an occluded front does not simply stay stationary, nor does it only occur in winter storms, each of which would misrepresent the broader phenomenon present in various climates.
