Hadley Cell Circulation

Answer the following questions:

Hadley Cell Circulation. Use Figures 1 and 2 above to explain how Hadley cells work. Your explanation should answer the following questions.
What is the intertropical convergence zone? What processes lead to the formation of the ITCZ? How does the intertropical convergence zone drive Hadley circulation?
How does Hadley circulation and Coriolis force work to create trade winds? In which direction do the trade winds blow for a given hemisphere?
How does this pattern of circulation correspond to the formation of rain forests near the equator and deserts near 30° latitude N/S?
Developing Critical Thinking. Climate models predict that the Hadley Cell may expand to higher latitudes as the earth warms. What do you think are some consequences of expanding Hadley cells terms of current ecosystems?
Midlatitude Highs and Lows.
What are the differences in weather associated between high and low pressure systems?
Why are there high pressure systems over the ocean in the summer hemisphere between 30° to 40° latitude N/S and low pressures observed over land?
Why do you think this pattern reverses in winter?
Developing Critical Thinking. What do you expect will happen as a consequence of the tremendous low pressure system over the Arabian Peninsula and India in the summer?
The Polar Climate.
Using the concept of high pressures and the observation of the low tropopause over the poles, explain why are polar regions dry?
Developing Critical Thinking. What can you say about ice sheet formation at the poles knowing that the region is typically dry? How long do you think ice accumulation takes?
