Question

Quizplus · Accepted Answer

Occlusion occurs when a fast-moving cold front overtakes a slow-moving warm front in a midlatitude wave cyclone. This can cause the warm air to be lifted, creating a narrow strip of moderate to heavy precipitation along the occluded front. Therefore, choice B is the best answer as it describes the scenario where the cold front is moving faster than the warm front.
