Answer 1

d. an occluded front

Step-by-step explanation:

In an occluded front, the trailing cold front overtakes the preceding warm front. This is conventionally described as the cold front “catching up” to the warm front. However, while it’s true that cold fronts tend to move faster than warm fronts, recent research suggests more underlying cyclonic processes cause the frontal mashup. Regardless, an occluded front involves the warm air behind the warm front behind forced aloft, the low-pressure center of the cyclone moving away from the frontal boundary, and the cold front coming into contact with the cold air mass originally downwind (so to speak) of the warm front.
