Describe the various ways in which an occluded front can form
What will be an ideal response?
Answer: Occluded fronts may form when a faster-moving cold front "catches up" to the warm front ahead. If the overtaking air mass is colder, it produces a cold-type occlusion. If the trailing air mass is warmer, the model suggests a warm-type occlusion will form. Occlusions also arise from deformations in the flow around a cyclone. For example, occlusions sometimes occur when the circular core of low pressure near the junction of the cold and warm fronts changes shape and stretches backward, away from its original position at the junction of the cold and warm fronts.
