Introduction to Atmospheric Sciences (ATOC-210) Assignment # 6, due April 6/09 1) Explain how and why the average surface pressure features shift from summer to winter? The position of the major features of the general circulation would change. In summer, the subtropical highs and ITCZ would be displaced farther north than now; in the winter, the subtropical highs and polar front would move farther south than they now do. (figure 10.3, page 260-261) 2) Explain why freezing rain more commonly occurs with warm fronts than with cold fronts. Freezing rain is more common with warm front because with a warm front, warm air rides up and over cold surface air. It is the warm rain falling into the cold, stable surface air that produces freezing rain. Often, behind a cold front the air becomes colder aloft. (pages 296-302) 3) Over the earth as a whole, would you expect the atmosphere to be mainly barotropic or baroclinic? Explain. Baroclinic conditions exist only in isolated regions of the atmosphere, such as above the
