2qr. How does a continental arctic air mass differ from a continental polar air mass? Get solution
2qt. Explain how an autumn anticyclone can bring record low temperatures and continental polar air to the southeastern United States and, only a day or so later, bring record high temperatures and maritime tropical air to the same region. Get solution
3qr. Why is continental polar air not welcome to the Central Plains in winter and yet very welcome in summer? Get solution
3qt. During the winter, cold-front weather is typically more violent than warm-front weather. Why is this so? Explain why this is not necessarily true during the summer. Get solution
4qr. What are lake-effect snows and how do they form? On which side of a lake do they typically occur? Get solution

5qr. Explain why the central United States is not a good air-mass source region. Get solution
5qt. Why does the same cold front typically produce more rain over Kentucky than over western Kansas? Get solution
6qr. . List the temperature and moisture characteristics of each of the major air mass types. Get solution
6qt. Explain why the boundaries between neighboring air masses tend to be more distinct during the winter than during the summer? Get solution
7qr. Which air mass only forms in summer over the southwestern United States? Get solution
7qt. Sketch a Southern Hemisphere mid-latitude cyclonic storm, complete with isobars and at least two types of fronts. Compare and contrast this Southern Hemisphere cyclone with its Northern Hemisphere counterpart. Get solution
8qr. Why are maritime polar air masses along the east coast of the United States usually colder than those along the nation’s west coast? Why are they also less prevalent? Get solution
8qt. Why are mid-latitude cyclones described as waves? Get solution
9qr. Explain how the air flow aloft regulates the movement of air masses. Get solution
9qt. Explain how this can happen: At the same time a midlatitude cyclonic storm over the eastern United States is moving northeastward, a large surface high-pressure area over the northern plains is moving southeastward. Get solution
10qr. The boundaries between neighboring air masses tend to be more distinct during the winter than during the summer. Explain why. Get solution
10qt. Would a wave cyclone intensify or dissipate if the upper trough was located to the east of the surface low-pressure area? Explain your answer with the aid of a diagram. Get solution
11qr. What type of air mass would be responsible for the weather conditions listed below? (a) hot, muggy summer weather in the Midwest and the East; (b) refreshing, cool, dry breezes after a long summer hot spell on the Central Plains; (c) persistent cold, damp weather with drizzle along the East Coast; (d) drought with high temperatures over the Great Plains; (e) record-breaking low temperatures over a large portion of North America; (f) cool weather with showers over the Pacific Northwest; (g) daily afternoon thunderstorms along the Gulf Coast Get solution

15qr. Why do mid-latitude cyclones tend to develop along the polar front? Get solution
16qr. List four regions in North America where mid latitude cyclones tend to develop. Get solution
17qr. Why is it important that for a surface low to develop or intensify, its upper-level counterpart must be to the left (or west) of the surface storm? Get solution
18qr. If upper-level diverging air above a surface area of low pressure exceeds converging air around the surface low, will the surface low weaken or intensify? Explain. Get solution
