1- On a piece of paper, draw the different stages of a mid-latitude cyclonic storm as it goes through birth to decay according to the polar front (Norwegian) model?

2- Why do mid-latitude cyclones usually “die out” after they become occluded?

3- list four regions in North America where mid- latitude cyclones tend to develop or redevelop?

6- If upper- level diverging air above a surface area of low pressure exceeds converging air surface low- pressure around the surface low, will the surface low-pressure area weaken on intensify? explain

10- What are the necessary ingredients for a mid-latitude cyclonic storm to develop into a huge storm system?

11- Why do surface storms tend to dissipate “fill” when the upper-level low and the surface low and the surface low become vertically stacked?

12 How does the polar-front jet stream influence the for-mation of a mid-latitude cyclone?
